Objective: The primary objective of this study was to identify novel genes that predispose people in the Japanese population to FPC.

Summary Of Background Data: Familial history of pancreatic cancer is an important risk factor but, to date, few genes predisposing individuals to increased risk of developing FPC have been identified.

Methods: We performed whole-exome sequencing of germline DNA from 81 Japanese FPC patients.

Article Synopsis
  • The study explored how both epigenomic and genomic changes contribute to the development of gastric cancer, using samples from normal, non-cancerous, and cancerous gastric tissues.
  • Analysis revealed that significant DNA methylation changes occurred even in non-cancerous tissues, suggesting these alterations are inherited by cancerous tissues.
  • Specific genetic changes were linked to different aggression levels of cancer clusters, with certain genes highlighted as crucial in signaling pathways that influence cancer progression and cell behavior.

Purpose: Usual interstitial pneumonia (UIP) is a risk factor for lung carcinogenesis. This study was performed to characterize mutagenesis and mutational target genes underlying lung carcinogenesis in patients with UIP.

Patients And Methods: A cohort of 691 Japanese patients with lung adenocarcinoma (LADC), of whom 54 had UIP and 637 did not, was studied for driver oncogene aberrations.

CpG-island methylator phenotype (CIMP)-positive clear cell renal cell carcinomas (RCCs) are characterized by accumulation of DNA hypermethylation of CpG islands, clinicopathological aggressiveness and poor patient outcome. The aim of this study was to clarify the molecular pathways participating in CIMP-positive renal carcinogenesis. Genome (whole-exome and copy number), transcriptome and proteome (two-dimensional image converted analysis of liquid chromatography-mass spectrometry) analyses were performed using tissue specimens of 87 CIMP-negative and 14 CIMP-positive clear cell RCCs and corresponding specimens of non-cancerous renal cortex.

This report delivers a comprehensive genetic alteration profile of lung adenocarcinomas (LADC) driven by ALK, RET, and ROS1 oncogene fusions. These tumors are difficult to study because of their rarity. Each drives only a low percentage of LADCs.
