Multiomics analysis reveals the involvement of NET1 in tumour immune regulation and malignant progression.

Sci Rep

January 2025

Department of General Surgery, The Second Xiangya Hospital, Central South University, No. 139 People's Road, Changsha, 410011, Hunan, People's Republic of China.

Neuroepithelial cell transforming gene 1 (NET1) is a member of the Ras homologue family member A (RhoA) subfamily of guanine nucleotide exchange factors and a key protein involved in the activation of Rho guanosine triphosphatases, which act as regulators of cell proliferation, cytoskeletal organization, and cell movement and are crucial for cancer spread. Research has shown that NET1 can regulate the malignant biological functions of tumour cells, such as growth, invasion, and metastasis, and it is closely related to the progression of pancreatic cancer, gastric cancer, and liver cancer. However, the comprehensive role and mechanistic function of NET1 in other types of cancer remain largely unexplored.

December 2024

General surgery department, China-Japan Friendship Hospital, 2 Yinghua East Street, Chaoyang District, Beijing, 100029, P.R. China. Electronic address:

Article Synopsis
  • Studies reveal that circular RNAs, particularly circPFKP, play a significant role in regulating gastric cancer cell behavior.
  • The research identified circPFKP as being down-regulated in gastric cancer tissues, and its overexpression inhibits cancer cell proliferation, migration, and invasion.
  • circPFKP operates by sponging miR-346, which influences CAMD3 expression, suggesting that targeting this axis may open new avenues for gastric cancer diagnosis and treatment.

Exosomal miR-552-5p Regulates the Role of NK Cells in EMT of Gastric Cancer via the PD-1/PD-L1 Axis.

J Cancer

January 2025

Department of Gastroenterology and Respiratory Internal Medicine & Endoscopy Center, Guangxi Medical University Cancer Hospital, Nanning, Guangxi 530021, P.R. China.

While previous studies have established the role of exosomal miR-552-5p in promoting gastric cancer (GC) progression, the exact mechanisms through which it modulates the PD-1/PD-L1 axis to affect NK cell function and subsequently influence GC epithelial-mesenchymal transition (EMT) remain to be elucidated. Western blot, transmission electron microscopy (TEM), and nanoparticle tracking analysis were used to characterize exosomes that were isolated from GC cell supernatants. Subcutaneous AGS cell injections expressing either Lv-miR-552-5p or Lv-NC were administered to nude BALB/C mice.

The management of gastrointestinal anastomotic leaks post surgery is a considerable challenge, characterized by elevated morbidity and mortality, particularly in cases of esophageal-jejunal anastomotic leaks. Diverse endoscopic intervention techniques have been utilized with enhanced success. We present a case where a 57-year-old patient with Siewert type II esophageal cardia cancer underwent endoscopic deployment of a fully covered stent into a fistula resulting from anastomotic leakage, following a laparoscopic proximal gastrectomy with Roux-en-Y and double tract reconstruction.

Article Synopsis
  • The report discusses two cases of colonic perforation that happened after an upper gastrointestinal series (UGIS) using barium, highlighting both its benefits for detecting gastric issues and its rare but serious risks.
  • It outlines the mechanisms behind perforation, identifies risk factors, and reviews imaging diagnosis challenges along with treatment options like Hartmann's procedure or colostomy, underscoring the importance of prompt diagnosis and surgical action.
  • The findings suggest that while UGIS is generally safe, awareness of its potential dangers is crucial, and advancements in endoscopic techniques may lead to a shift towards endoscopy as a preferred screening method in the future.
