Identification of three genes that determine the stemness of gastric tissue stem cells
Tissue stem cells can self-renew and differentiate, supplying cells necessary for tissues at various developmental stages. However, detailed analysis in vivo is difficult, so the molecular mechanisms underlying the stemness of gastric tissue stem cells have remained a mystery. Here, by using organoids that mimic tissue structure and function in vivo and GeCKO screening to inactivate arbitrary genes, Alk, Bclaf3 and Prkra have been identified as genes regulating stemness.

Deepfake detectors can be defeated, computer scientists show for the first time
Systems designed to detect deepfakes --videos that manipulate real-life footage via artificial intelligence--can be deceived, computer scientists showed for the first time at the WACV 2021 conference which took place online Jan. 5 to 9, 2021. Researchers showed detectors can be defeated by inserting inputs called adversarial examples into every video frame. The adversarial examples are slightly manipulated inputs which cause artificial intelligence systems such as machine learning models to make a mistake. (2021-02-08)

Researchers at Karolinska Institutet and Danderyd Hospital in Sweden have studied the risk of additional myocardial infarctions and early death in severely obese patients who undergo metabolic surgery following a myocardial event. The registry study covering 1,018 individuals shows a lower risk of additional myocardial infarctions and improved survival that cannot be simply attributed to the loss of weight. The study is published in the journal Circulation. (2020-10-26)

Cutting cancer off at the head
Using a 2 ml blood sample from 100 gastric cancer patients, researchers succeeded in identifying cancer cells circulating in the bloodstream and trace them back to their origin tumor by detecting an overexpression of fibroblast growth factor receptor (FGFR2) in both the cancer cells and the tumor. This new diagnostic method may allow for real-time detection of the growth patterns of the cancer, leading to quicker and more accurate preventative action -- essentially cutting the cancer`s potential metastasizing off at the head.

Immune protein IL-17A responsible for lethal side effects of gastric cancer
The formation of scar tissue, or fibrosis, as gastric cancer disseminates throughout the peritoneum can be more lethal than the cancer itself and can interfere with chemotherapy. Researchers from Kanazawa University have now found that proinflammatory cytokine IL-17A from mast cells heavily influences the degree of fibrosis and causes structural changes in peritoneal cells. Preventing mast cells from releasing IL-17A may therefore be a promising treatment strategy for gastric cancer patients with peritoneal dissemination. (2020-08-26)

Tweaking the adenovirus spike protein induces a more robust immune reaction for a cancer vaccine against gastric, pancreatic, esophageal and colon malignancies in animal models. (2020-08-24)

Molecule secreted by cancer-associated fibroblasts promotes anticancer drug resistance
Joint research at Kumamoto University in Japan discovered a new mechanism for anticancer drug resistance in gastric cancer. Experiments clarified that the Annexin A6 molecule contained in extracellular vesicles (EVs) is secreted by cancer-associated fibroblasts (CAFs) and taken up by gastric cancer cells, resulting in resistance to anticancer drug treatment. New drug development that targets Annexin A6 and cancer-associated fibroblasts (CAFs) may be possible. (2020-08-21)

Major weight loss -- whether from surgery or diet -- has same metabolic benefits
A longstanding theory has suggested that gastric bypass surgery may have unique, weight loss-independent effects in treating type 2 diabetes. But new research from Washington University School of Medicine in St. Louis indicates that weight loss after surgery, rather than the surgery itself, drives metabolic improvements, such as the remission of diabetes. (2020-08-19)
