Abstract
Fanconi Anemia (FA) is a rare inherited hematological disease, caused by mutations in genes involved in the DNA interstrand crosslink (ICL) repair. Up to date, 22 genes have been identified that encode a series of functionally associated proteins that recognize ICL lesion and mediate the activation of the downstream DNA repair pathway including nucleotide excision repair, translesion synthesis, and homologous recombination. The FA pathway is strictly regulated by complex mechanisms such as ubiquitination, phosphorylation, and degradation signals that are essential for the maintenance of genome stability. Here, we summarize the discovery history and recent advances of the FA genes, and further discuss the role of FA pathway in carcinogenesis and cancer therapies.

Introduction
Fanconi anemia (FA) is a rare hereditary disease featured by a series of clinical manifestations including bone marrow failure, microcephaly, and absence or hypoplasia of radius and/or thumb (Auerbach, 2009); and the cells from FA patients exhibit characteristic hypersensitivity to DNA cross-link agents (Schneider et al., 2015). The clinical syndrome is widely distributed across different countries and populations, and is estimated to be 1 in every 100,000 newborns in the West (Nalepa & Clapp, 2018).
Fanconi anemia was named after the Swiss pediatrician Guido Fanconi who firstly described a case of this syndrome in 1927 (Lobitz & Velleuer, 2006). During his training as a pediatric at the children’s hospital of the University of Zurich, Guido Fanconi encountered a family in which three brothers died of a disease resembling pernicious anemia with a variety of congenital abnormalities but without signs of typically increased hemolysis. Following several other case reports, speculations about the etiology and hereditary pattern of this disease rises. Nearly 40 years after Fanconi’s description of the disorder, the enthusiasm of exploring the chromosomal abnormalities drove researchers to discover that the cells of FA patients had an elevated rate of chromosomal aberrations (Swift & Hirschhorn, 1966), and the FA was proved to be an autosomal recessive hereditary disorder (except one subtype which is X-linked) (Nalepa & Clapp, 2018).
The first identified FA gene is FANCC which accounts for about 14% of Fanconi anemia cases (Dong et al., 2015) and its c.711 + 4A > T is a dominant mutation in Ashkenazi Jews patients (Kutler & Auerbach, 2004). FANCC gene was successfully identified and its cDNA was cloned nearly 65 years after Guido Fanconi’s first case report (Strathdee et al., 1992). Then after 4 years since the first FANCC gene was cloned, the FANCA gene was cloned and reported, which was the second identified FA gene (Lo Ten Foe et al., 1996). Mutations in FANCA is responsible for the largest percentage of Fanconi anemia cases (over 65%), more than 500 pathogenic variants of FANCA gene have been determined in the Fanconi Anemia Mutation Database (Dong et al., 2015). FANCE and FANCF were identified with complementation cloning method in 2000 (b; de Winter, Leveille, et al., 2000). They are together responsible for 8% of mutations in Fanconi anemia cases (Schneider et al., 2015). FANCG gene was found to be identical with previously discovered human XRCC9 (X-ray repair, complementing defective repair in Chinese hamster cells 9), which was derived from the MMC-sensitive Chinese hamster mutant UV40 and was thought to be functional in the process of DNA post-replication repair (Winter et al., 1998). The other identified FA genes account for a small fraction (about 5%) of Fanconi anemia cases (Dong et al., 2015). As the knowledge to FA pathway develops, more and more genes were included into the FA family, such as BRCA1/2, PALB2, RAD51 and others (Table 1). Up to now, 22 FA genes have been identified, as listed in Table 1; more FA genes would be identified in the future since the known mutations in the FA family still could not shed light on all the FA cases till now.
The function and working mechanism of FA pathway
FA pathway involves a bunch of FA proteins and other associated proteins, constituting a system serving for inter-strand cross-link (ICL) DNA repair in the S phase (Ceccaldi et al., 2016; Milletti et al., 2020), which coordinates each critical step by interacting with various DNA damage repair (DDR) proteins (Kottemann & Smogorzewska, 2013). ICL is a special type of DNA lesions that are a covalent linkage between opposite strands of double-stranded DNA (Fig. 1A). This kind of lesion prevents separation of DNA helix, making replication and transcription disturbed (Deans & West, 2011). In addition, ICL is also responsible for chromosomal aberrations and lethal DNA breaks (Vogel et al., 1998). Generally, in G1 phase, ICL lesions could be recognized and repaired by nucleotide excision repair (NER) machinery (Sarkar et al., 2006); while in S phase, ICL causes the stalling of DNA replication forks, which leads to the activation of FA pathway and the initiation of the DDR system (McHugh et al., 2001; Noll et al., 2006). During the process of DNA replication, the replication fork stops at the ICL lesion, inducing the replicative helicase complexes (CMG) to detach from the DNA strands upon the effect of the BRCA1 (Long et al., 2014) (Fig. 1A). Encounter with ICL lesion might lead to the shutdown of the replication fork, and this process would trigger downstream response about DNA repair and activation of ATR, which is essential for the subsequent activation of FA proteins. The FA pathway starts with ATP-dependent DNA translocase FANCM, and histone-like MHF complex (MHF1-MHF2-FAAP24), which recognizes and binds to the DNA damage portion and recruits other FA proteins (Collis & Boulton, 2010; Ling et al., 2016; Xue et al., 2008) (Fig. 1A). In this process, FANCM is activated by ATR, and is recruited to the ICL portion depending on its DNA-binding partners FAAP24, BLM complex, and the translocase activity of itself (Ling et al., 2016; Meetei et al., 2003).
FANCM further recruits the FA core complex, which is composed of a series of FA proteins as shown in Fig. 1B and Table 1. FA core complex and FANCM-BLM complex coordinate to unwind the DNA and promote the repair of replication fork (Deans & West, 2009; Meetei et al., 2003). FA core complex then catalyzes the mono-ubiquitination of FANCI and FANCD2, two members of ID2 complex, which is the critical step to activate ICL repair (Fig. 1B). Although perfect ubiquitination requires an integrated FA core complex, this process only necessarily needs an L-B-100 complex (FANCL-FANCB-FAAP100) (Rajendra et al., 2014), within which, the E3 ubiquitin ligase FANCL coordinates with UBE2T (another ubiquitin E2 ligase), playing the major role for the ubiquitination reaction. Additionally, UBL-5 and PCNA-ub are both required for the monoubiquitylation of FANCD2 (Howlett et al., 2009). Notably, the ubiquitination process of ID2 complex is reversible, catalyzed by the deubiquitinase USP1 and UAF1, which are responsible for the decruitment of ID2 complex after repair (Nijman et al., 2005).
The ubiquitinated ID2 complex further recruits structure-specific endonuclease to excise the stalled replication fork, such as XPF and FAN1. XPF-ERCC1 is an efficient incision endonuclease whose preferred substrate is the splayed arms DNA structure caused by ICL (Zhang & Walter, 2014), and it could be recruited to ICL lesions by ubiquitinated FAND2 (Klein Douwel et al., 2014). Similar to XPF, FAN1 could also be recruited by ubiquitinated FANCD2 via its UBZ4-type ubiquitin binding domain (Kratz et al., 2010), but this is not compelling in some cases (Zhang & Walter, 2014). Another essential scaffold protein mediating the endonuclease recruitment to ICL lesions is SLX4 (FANCP). SLX4 works together with SLX4IP, a constitutive factor in the SLX4 complex (Zhang et al., 2019), to recruit multiple nucleases such as XPF-ERCC1, MUS81-EME1 andSLX1to the ICL lesions for incisions (Klein Douwel et al., 2014; Sridharan et al., 2003); within which, the XPF–ERCC1–SLX4-SLX1 (XESS) complex is indispensable for the endonuclease activity in ICL repair (Zhang & Walter, 2014; Zhang et al., 2019) (Fig. 1C). Although some former studies reported ubiquitinated FAND2 was responsible for the recruitment of SLX4 (Yamamoto et al., 2011), the detailed molecular mechanism remains controversial since some other evidence showed the recruitment of SLX4 to ICL was independent on FANCD2 (Lachaud et al., 2014).
After incision, the cross-linked DNA would hang on the other strand, then the translesion synthesis (TLS) process would be launched. In the TLS process, PCNA-ub and the FA core complex recruit TLS polymerases such as REV7 (FANCV), polymerase ζ and REV1 to form a polymerase complex (Ceccaldi et al., 2016; Waters et al., 2009). Among those polymerases, the REV1-Polζ complex plays a leading role, recruited by FAAP20 in the core complex (Kim et al., 2012). Compared to the other DNA replication polymerases, the TLS polymerases have a larger binding pocket to adapt the ICL adduct (Ceccaldi et al., 2016); moreover, they could recognize PCNA-ub by the ub-binding domain which was not possessed by the other replication polymerases (Burschowsky et al., 2011) (Fig. 1D). While TLS produces a nice double strand, the incised portion remains a double-strand break (DSB) waiting for homologous recombination (HR) pathway to repair it. To launch HR repair, FANCD2 cooperates with BRCA1 and MRE11 to recruit CtIP, a key resection factor (Andres & Williams, 2017; Ceccaldi et al., 2016), to direct MRN complex (MRE11, RAD50 and NBS1) to cut the DSB portion and produce a 3’ single-strand (ss) DNA tail to invade into the homologous DNA strands (Liu & Huang, 2016) (Fig. 1E). During the DNA recombination, the recombinase RAD51 is responsible for forming the single-strand DNA nucleofilaments and strand invasion (Prakash et al., 2015) (Fig. 1F), which is recruited by BRCA2 (FANCD1)–PALB2 complex (Long et al., 2011; Shahid et al., 2014). Then a nascent DNA strand is synthesized by HR pathway to form an intact DNA duplex (Fig. 1F).
Like homologous recombination repair pathway, the FA pathway is also cell cycle dependent. During the process, double-strand break is accompanied by the ICL lesion excision, which is finally repaired by HR. Thus, a successful repair of ICL not only depends on normal FA genes, but also a intact HR pathway.
Association of FA genes with cancer
In clinic, a major cause for the death of FA patients is the cancer development in addition to bone marrow failure. A large population survey including 111 FA patients indicates a cancer frequency of 30%, with a median onset age before 20 (Steinberg-Shemer et al., 2020). Myeloid leukemias, liver tumors, head and neck carcinomas, and gynecologic malignancies are the most profound predisposing cancers among FA patients (Niraj et al., 2019). In clinical tumor tissues, either familial or sporadic cancer, the FA gene mutations are also common (Table 2), suggesting a intrinsic relationship between FA pahway and carcinogenesis. The reason behind is the critical function of FA pathway in maintaining genome stability. Deficient FA pathway causes genome instability resulting in accumulation of mutations, which gives additional survival advantages for the FA gene mutated cells, accerlerating the carcinogenesis process for some kinds of malignant tumors. For example, deletion and low expression of FANCA is common in acute myelocytic leukemia (AML), prostate cancer and oral cancer (Mantere et al., 2015; Tischkowitz et al., 2004; Tremblay et al., 2006). Similarly, heterozygous mutation of FANCD2 was confirmed to be associated with esophageal cancer, childhood T-cell acute lymphoblastic leukemia (ALL) and testicular seminoma (Akbari et al., 2011; Smetsers et al., 2012). Another well-known example is BRCA1 and BRCA2 (FANCS and FANCD1), whose germline mutations lead to familial breast and ovarian cancer (Antoniou et al., 2003; Chen & Parmigiani, 2007). The breast cancer appears more relevant to FA pathway: except BRCA1/2, germline mutation of RAD51C (FANCO) is also associated with an increased risk of breast cancer (Levy-Lahad, 2010; Loveday et al., 2012), and FANCM mutation increases the susceptibility of triple-negative breast cancer (Kiiski et al., 2014). The relationship between FA gene mutations and cancer predisposition is summarized in Table 2.
The epigenetic aberrance such as DNA methylation of FA genes is also common in cancers, and some of them have cancer-type specificity. For example, the hypermethylation of CpG islands in the promoter regions of FANCC and FANCL were found in AML and ALL (Hess et al., 2008), whereas the other FA genes were rarely methylated in the leukemia (Meyer et al., 2006). In solid tumors, hypermethylation of FANCF was found in multiple cancer types. In sporadic lung adenocarcinoma, FANCF hypermethylation is a predictor of poor survival compared to those with hypomethlylation (Marsit et al., 2004; Nakajima et al., 2009). In cervical cancer (CC), hypermethylation of BRCA1 and FANCF co-excist in patient samples, suggesting an attenuating function of FA pathway in CC (Narayan et al., 2004). In sporadic breast cancer, low expression of FANCD2 is commonly observed, which is associated with an improved long-term therapeutic outcome (Feng & Jin, 2019).
With regard to cancer therapy, the FA pathway is a ideal target. Early studies demonstrated that elevation of FA gene expression is frequently associated with chemo-resistance, whereas disruption of FA pathway sentitizes tumor cells to ICL agents (Chen et al., 2007; Taniguchi et al., 2003). For example, enhanced FA pathway activation has been shown to be relevant to resistance to melphalan in multiple myeloma and pancreatic cancers (Liu et al., 2020). An A549 derived cisplatin resistant lung cancer cell line A549/DR exhibits overexpression of multiple FA genes and elevated FANCD2 monoubiquitination level compared to its parental cell line (Liu et al., 2020). Knocking down of FA genes re-sensitizes A549/DR cells to cisplatin treatments. Similarly, another study revealed that knocking down of FANCF attenuates invasiveness of breast cancer, and improves the cellular sensitivity to the DSB agents doxorubicin (Zhao et al., 2014).
Since FA genes exert their critical function in maintaining genome stability by DNA damage repair, researchers have developed numerous therapies targeting the FA-deficient tumors. For example, a study revealed that the FA-deficient tumors present higher sensitivity to ATM inhibitors (Kennedy et al., 2007), since these tumors depend on the compensatory roles of ATM on DNA damage repair. Another successful example is the PARP inhibitor, which is highly effective in BRCA1 or BRCA2-deficient tumors based on their defect homologous recombination repair function (Bryant et al., 2005; Nalepa & Clapp, 2018). Since both chemotherapy re-sensitization and synthetic lethality will benefit from FA pathway inhibition, multiple approaches have been employed for the development of FA-specific inhibitors, but only a few of FA proteins including FANCL, FANCM, FANCR and FANCV have successful specific inhibitors (Brouwer et al., 2018; Hara et al., 2017; Lu et al., 2019). Some of the inhibitors exhibit excellent anti-cancer effect in preclinical study (Liu et al., 2020), while more FA inhibitors are still in demand. On the other hand, inhibiting FA proteins in cancer therapy is a double-edge sword. As the FA pathway mediates tumor suppression, targeting the FA pathway may further enhance genomic instability in tumor, which leads to increased genetic diversity and intratumoral heterogeneity, potentially promoting tumor progression and drug resistance after long-term treatment (Andor et al., 2017; Dagogo-Jack & Shaw, 2018). Another concern of FA inhibitors is it may bring other health issues, including anemia and a secondary tumor after long-term use, since genomic instability may promote carcinogenesis in healthy organs or tissues. Thus the clinical use of FA inhibitors needs cautious verification. Above all, although targeting FA pathway is a promising in cancer therapy, it remains a long way to transfer the lab findings into clinical practice.
Conclusion
As the rapid development of molecular biological research, people are increasingly understanding FA genes and their function. It is well established that the FA pathway plays a central role in ICL repair during which the FA proteins coordinate other DDR proteins to ensure the repair process and the genome stability. In the absence of FA genes, cells are predisposed to spontaneous DNA damage, leading to additional chromosomal aberrations which is closely associated with pernicious anemia and cancer. Understanding the molecular mechanism of FA pathway and other DNA repair pathways is greatly helpful for advancing cancer research. Moreover, novel treatment targeting FA pathway may play an important role for the development of personalized therapies to improve the clinical outcome of cancer patients.
