Introduction Pancreatic cancer (PC) is one of the most aggressive and lethal cancers (1). Previous studies have shown that aging, environmental and behavioral changes are more closely related to the dramatic increase in the incidence of PC worldwide than genetic factors (2–5). A position paper published by the European Federation…

Introduction Oocyte competence and quality depend on communication between the oocyte and the cumulus and theca cells. In the preantral phase, the members of the transforming growth factor β (TGF-β) superfamily are responsible for this communication and play an important role in folliculogenesis. Members of the TGF-β superfamily are related…

Purpose: Hepatitis B virus (HBV) plays a crucial role in the progression of hepatocellular carcinoma (HCC). It is known that HBV-encoded X protein (HBx) can induce genetic alterations in some oncogenes and that SMAD4 is relevant for the development of some cancers, especially HBV-related HCC. Previously, it has been reported…

For a study, the researchers sought to see if genomic risk groups discovered by colorectal liver metastasis (CRLM) somatic mutation testing may be used for “molecularly-guided” adjuvant systemic chemotherapy and hepatic artery infusion of FUDR (SYS+HAI-FUDR). A prospective institutional database was analyzed for consecutive patients with resected CRLM and available…

Introduction Hepatic fibrosis (HF) is a pathological phenomenon produced in the process of long-term damage and repair in the liver [1,2]. During the formation of HF, hepatocytes are damaged by various factors, such as chronic liver disease, and excessive intake of alcohol, and secrete a variety of cytokines [3]. Subsequently,…

ABSTRACT Colorectal carcinoma with noncohesive tumor cells has been described in tumors with signet ring cells (mucinous adenocarcinoma and signet ring cell adenocarcinoma) and rhabdoid feature (carcinoma with sarcomatoid component). Cases of carcinoma with…

Introduction Most cases of pancreatic adenocarcinoma (PDAC) are diagnosed in the metastatic or locally advanced stage. It is the fourth leading cause of cancer death in the United States,1,2 with a 5-year overall survival (OS) around 10% in this country2 despite years of research and therapeutic development. For those patients…

The micro ribonucleic acid (microRNA) [MiR-181a] is downregulated in the kidneys of rodents and patients suffering from high blood pressure (BP). The miR-181a is a posttranslational inhibitor of renin articulation in vitro, yet pleiotropic systems by which miR-181a may impact BP are unclear. Whether cancellation of miR-181a/b-1 in vivo changes…

Introduction Pancreatic ductal adenocarcinoma (PDAC) is a lethal gastrointestinal disease with increasing morbidity, which also has a growing impact on cancer-specific mortality worldwide.1 Nearly 40% of all PDAC cases are localized to the pancreas and characterized with the involvement of major vascular structures, leading to unresectable disease without metastases detected…

Possible biomarkers for prognosis and clinical outcomes were identified, through the use whole exome sequencing and RNA sequencing, as therapeutic targets for patients with pancreatic ductal adenocarcinoma (PDAC), according to a recent study. The study, published in Therapeutic Advances in Medical Oncology, also reconfirmed genomic landscapes, major driver mutations, and…
