Hepatocellular carcinoma, cholangiocarcinoma and gallbladder cancer have different biological characters, histopathological traits, and treatment strategies, but have similar clinical features such as silent early symptom and extremely poor prognosis. The diagnostic, predictive or prognostic tumor biomarkers of hepatobiliary cancers are in unmet need. In contrast to the poor outcome, the treatment options to hepatobiliary cancers are very limited. It is still controversial about the effects of chemotherapy and radiotherapy of hepatobiliary cancer. FDA-approved targeted drugs are only Sorafenib and Lenvatinib for hepatocellular carcinoma, and Pemigatinib for cholangiocarcinoma. Unfortunately, these drugs are only effective for 5%-30% patients. Therefore, more attention should be called upon on investigating effective biomarkers and drug targets, stratifying high-risk patients, guiding precise treatments, and developing therapeutic strategies for hepatobiliary cancers. This Research Topic aims at discussing the current knowledge and proceedings of diagnostic, predictive and prognostic tumor biomarkers in hepatobiliary cancer, and presenting the recent advances on new drug targets and potential targeted therapies of hepatobiliary cancer. We welcome submissions of Review, Mini-Review, Clinical Trial and Original Research articles covering, but not limited to, the following topics: 1. new diagnostic/prognostic factors, biomarkers and/or risk factors in hepatobiliary tumors 2. new drug targets, and oncogenic or tumor suppressive molecular mechanism of the novel targets 3. new intervention or targeted therapy in hepatobiliary tumors 4. new findings of bioinformatics or high-throughput methods such as mass spectrometry and genome-wide association studies or which may help screen the potential biomarkers of hepatobiliary tumors 5. clinical studies such as cohort study or RCT to identify new risks or treatment therapies in hepatobiliary tumors 6. basic, pharmacological, preclinical or clinical study of potential drugs targeting hepatobiliary tumors Please note: manuscripts consisting solely of bioinformatics or computational analysis of public genomic or transcriptomic databases which are not accompanied by validation (independent cohort or biological validation in vitro or in vivo) are out of scope for this section and will not be accepted as part of this Research Topic.

Naturally occurring RNA always contains numerous biochemically altered nucleotides. They are formed by enzymatic modification of the primary transcripts during the complex RNA maturation process designated RNA modification. A large number of enzymes catalyzing the formation of these modified nucleosides or converting one canonical base into another at the posttranscriptional level have been studied for many years, but only recently have systematic and comparative studies begun. The functions of individual enzymes and/or the modified/edited nucleosides in RNA, however, have remained largely ignored. This book provides advance information on RNA modification, including the associated editing machinery, while offering the reader some perspective on the significance of such modifications in fine-tuning the structure and functions of mature RNA molecules and hence the ability to influence the efficiency and accuracy of genetic expression. Outstanding scientists who are actively working on RNA modification/editing processes have provided up-to-date information on these intriguing cellular processes that have been generated over the course of millions of years in all living organisms. Each review has been written and illustrated for a large audience of readers, not only specialists in the field, but also for advanced students or researchers who want to learn more about recent progress in RNA modification and editing.

In an era of promising advances in cancer research, there are considerable and even alarming gaps in the fundamental knowledge and understanding of ovarian cancer. Researchers now know that ovarian cancer is not a single disease-several distinct subtypes exist with different origins, risk factors, genetic mutations, biological behaviors, and prognoses. However, persistent questions have impeded progress toward improving the prevention, early detection, treatment, and management of ovarian cancers. Failure to significantly improve morbidity and mortality during the past several decades is likely due to several factors, including the lack of research being performed by specific disease subtype, lack of definitive knowledge of the cell of origin and disease progression, and incomplete understanding of genetic and non-genetic risk factors. Ovarian Cancers examines the state of the science in ovarian cancer research, identifies key gaps in the evidence base and the challenges to addressing those gaps, considers opportunities for advancing ovarian cancer research, and examines avenues for translation and dissemination of new findings and communication of new information to patients and others. This study makes recommendations for public- and private-sector efforts that could facilitate progress in reducing the incidence of morbidity and mortality from ovarian cancers.

Translational medicine was first mentioned in 1992 by Choi D. W and has since become a rapidly expanding area within biomedical research. It is based on the ‘bench to bedside’ approach, which describes it’s relationship between basic science and clinical practice. In 2008, Drs Conway and Dougherty provided a 3 step process to translational medicine and how it should be implemented to transform healthcare systems. The first step is the translation of basic science into clinical research (T1). The second step (T2) focuses on making healthcare more patient specific, basing itself on providing ‘the right treatment for the right patient in the right way at the right time’. T2 also looks for this science to be translated into practice guidelines for clinicians, policy makers and the patients themselves. The final step (T3) addresses the ‘how’ of implementing these ideas, so that high quality healthcare can be delivered reliably to all patients in all settings of care. T3 activities would include policy changes that could serve to bring about meaningful change towards this goal. Cancer is a major public health problem worldwide. Clarifying the etiology and pathogenesis of cancer is of great significance to the prevention, diagnosis, and treatment of the disease. The bench to bedside pattern can be a useful method for cancer-related studies. This Research Topic aims to highlight the emerging role of oncogenetics in cancer, and discuss potential challenges of diagnosis and treatment, from the bench to the bedside.

Colorectal cancer has for more than two decades served as the paradigm for the multi-step concept of cancer initiation and progression. Perhaps more than any other organ site, cancer of the colon is extensively characterized at the molecular level. We are now entering a time when molecular classification, rather than histologic classification, of cancer subtypes is driving the development of clinical trials with emerging targeted therapies. The book will focus on the progression from the identification of mutations that drive colorectal cancer initiation and progression to the search for novel therapies to treat the disease.
