Helicobacter pylori promotes gastric cancer progression by activating the TGF-β/Smad2/EMT pathway through HKDC1.

Helicobacter pylori (H. pylori) infection is widely acknowledged as the primary risk factor for gastric cancer, facilitating its progression via the Correa cascade. Concurrently, Hexokinase Domain Containing 1 (HKDC1) has been implicated in the mediation of aerobic glycolysis, contributing to tumorigenesis across various cancers.

CircRAPGEF5 acts as a modulator of RAS/RAF/MEK/ERK signaling during colorectal carcinogenesis.

Mutations in oncogenes such as , and promote the growth and survival of tumors, while excessive RAS/RAF/MEK/ERK activation inhibits tumor growth. In this study we examined the precise regulatory machinery that maintains a moderate RAS/RAF/MEK/ERK pathway activation during CRC. Here, using bioinformatic analysis, transcriptomic profiling, gene silencing and cellular assays we discovered that a circular RNA, circRAPGEF5, is significantly upregulated in KRAS mutant colorectal cancer (CRC) cells.

Targeting high circDNA2v levels in colorectal cancer induces cellular senescence and elicits an anti-tumor secretome.

The efficacy of immunotherapy against colorectal cancer (CRC) is impaired by insufficient immune cell recruitment into the tumor microenvironment. Our study shows that targeting circDNA2v, a circular RNA commonly overexpressed in CRC, can be exploited to elicit cytotoxic T cell recruitment. circDNA2v functions through binding to IGF2BP3, preventing its ubiquitination, and prolonging the IGF2BP3 half-life, which in turn sustains mRNA levels of the protooncogene c-Myc.

Long-term oncological outcomes of robotic versus laparoscopic gastrectomy for gastric cancer: multicentre cohort study.

Background: The aim of this multicentre cohort study was to compare the long-term oncological outcomes of robotic gastrectomy (RG) and laparoscopic gastrectomy (LG) for patients with gastric cancer.

Methods: Patients with gastric cancer who underwent radical gastrectomy by robotic or laparoscopic approaches from 1 March 2010 to 31 December 2018 at 10 high-volume centres in China were selected from institutional databases. Patients receiving RG were matched 1 : 1 by propensity score with patients undergoing LG.

Genetic correlation, shared loci, but no causality between bipolar disorder and inflammatory bowel disease: A genome-wide pleiotropic analysis.

Background And Aims: The comorbidity between bipolar disorder (BD) and inflammatory bowel disease (IBD) has been widely reported in observational studies. However, unclear whether this comorbidity reflects a shared genetic architecture.

Methods: Leveraging large-scale genome-wide association study (GWAS) summary statistics of BD, IBD and its subtypes, ulcerative colitis (UC) and Crohn's disease (CD), we performed a genome-wide pleiotropic analysis to estimate heritability and genetic correlation, identify pleiotropy loci/genes, and explore the shared biological pathway.

Targeting TLK2 inhibits the progression of gastric cancer by reprogramming amino acid metabolism through the mTOR/ASNS axis.

Several recent studies have suggested that TLKs are related to tumor progression. However, the function and mechanism of action of TLK2 in gastric cancer (GC) remain elusive. In this study, TLK2 was found to be significantly upregulated in patients with GC and was identified as an independent prognostic factor for GC.

FIT links c-Myc and P53 acetylation by recruiting RBBP7 during colorectal carcinogenesis.

Colorectal cancer (CRC) poses one of the most serious threats to human health worldwide, and abnormally expressed c-Myc and p53 are deemed the pivotal driving forces of CRC progression. In this study, we discovered that the lncRNA FIT, which was downregulated in CRC clinical samples, was transcriptionally suppressed by c-Myc in vitro and promoted CRC cell apoptosis by inducing FAS expression. FAS is a p53 target gene, and we found that FIT formed a trimer with RBBP7 and p53 that facilitated p53 acetylation and p53-mediated FAS gene transcription.

Hypoxia Inducible Factor-1alpha (HIF-1A) plays different roles in Gallbladder Cancer and Normal Gallbladder Tissues.

Hypoxia-inducible factor-1alpha (HIF-1A) is a transcription factor that plays an "angiogenic switch" role especially under hypoxia microenvironment in solid tumor. However, the functions and clinical significance of HIF-1A in gallbladder cancer (GBC) are still controversial, and it has not been studied in normal gallbladder tissues. In this study, we sought to clarify the role of sub-cellular localization of HIF-1A expression in GBC and normal gallbladder tissues.

A new method of robot-assisted laparoscopic repair of perineal hernia after abdominoperineal resection: a case report.

Introduction: Perineal hernia is a protrusion of the pelvic floor which contains intra-abdominal viscera. The occurrence of perineal hernia after abdominoperineal resection (APR) is rare, but it has been reported in recent years that the incidence of perineal hernia after rectal cancer surgery has increased. This has been attributed to a shift towards extralevator abdominoperineal resection, together with more frequent and long-term use of neoadjuvant therapy.

The correlation between NEDD4L and HIF-1α levels as a gastric cancer prognostic marker.

NEDD4L (neural precursor cell expressed developmentally down-regulated 4-like) protein is a member of ubiquitin ligases Nedd4 family. Although studies have shown that Nedd4L may act as a tumor suppressor in various cancers, including gastric cancer (GC), its clinical significance and the diagnostic value in GC is not well defined. HIF-1α (hypoxia inducible factor family of transcription factors) is actively involved in the metabolism of many tumors, although the relationship between its expression levels and clinical significance in GC still need to be established.

Low expression of RBMS3 and SFRP1 are associated with poor prognosis in patients with gastric cancer.

RNA binding motif, single stranded interacting protein 3 (RBMS3) has been reported as a tumor suppressor gene (TSG) in some squamous carcinoma. However, its expression levels and clinical significance in gastric cancer (GC) remains unclear. Secreted frizzled-related protein 1 (SFRP1) plays a role of tumor suppressor in many cancers by inhibiting Wnt/β-catenin pathway.
