Abstract
Ovarian cancer (OC) is a heterogeneous disease with the highest mortality rate and the poorest prognosis among gynecological malignancies. Because of the absence of specific early symptoms, most OC patients are often diagnosed at late stages. Thus, improved biomarkers of OC for use in research and clinical practice are urgently needed. The last decade has seen increasingly rapid advances in sequencing and biotechnological methodologies. Consequently, multiple omics technologies, including genomic/transcriptomic sequencings and proteomic/metabolomic mass spectra, have been widely applied to analyze tissue- and liquid-derived samples from OC patients. The integration of multi-omics data has increased our knowledge of the disease and identified valuable OC biomarkers. In this review, we summarize the recent advances and perspectives in the use of multi-omics technologies in OC research and highlight potential applications of multi-omics for identifying novel biomarkers and improving clinical assessments.

Abstract
Cancer develops through diverse genetic, epigenetic and other changes, so-called 'multi-step carcinogenesis', and each cancer harbors different alterations and properties. Here in this article we review how poly(ADP-ribosyl)ation is involved in multi-step and diverse pathways of carcinogenesis. Involvement of poly- and mono-ADP-ribosylation in carcinogenesis has been studied at molecular and cellular levels, and further by animal models and human genetic approaches. PolyADP-ribosylation acts in DNA damage repair response and maintenance mechanisms of genomic stability. Several DNA repair pathways, including base-excision repair and double strand break repair pathways, involve PARP and PARG functions. These care-taker functions of poly(ADP-ribosyl)ation suggest that polyADP-ribosyation may mainly act in a tumor suppressive manner because genomic instability caused by defective DNA repair response could serve as a driving force for tumor progression, leading to invasion, metastasis and relapse of cancer. On the other hand, the new concept of 'synthetic lethality by PARP inhibition' suggests the significance of PARP activities for survival of cancer cells that harbor defects in DNA repair. Accumulating evidence has revealed that some PARP family molecules are involved in various signaling cascades other than DNA repair, including epigenetic and transcriptional regulations, inflammation/immune response and epithelial-mesenchymal transition, suggesting that poly(ADP-ribosyl)ation both promotes and suppresses carcinogenic processes depending on the conditions. Expanding understanding of poly(ADP-ribosyl)ation suggests that strategies to achieve cancer prevention targeting poly(ADP-ribosyl)ation for genome protection against life-long exposure to environmental carcinogens and endogenous carcinogenic stimuli.
