Selenium Nanoparticles Selectively Target KRAS G13D to Inhibit Colorectal Cancer
Advanced Science, EarlyView.The mechanisms of SeNPs therapy in cancer treatment, encompass three parallel actions: (1) seleno‐amino acids, key metabolites, upregulate GPX2 expression, thereby inhibiting tumor metastasis via the GPX2‐HIF1α‐VEGF signaling pathway; (2) selenite (SeO32−), an inorganic metabolite, forms hydrogen bonds with amino acid residues 13–17 of the KRAS G13D ...

Clinical outcomes of endoscopic mucosal resection for rectal neuroendocrine tumor
BMC Gastroenterology, 2018 BackgroundThe incidence of rectal neuroendocrine tumors (NETs) is rapidly increasing because of the frequent use of endoscopic screening for colorectal cancers. However, the clinical outcomes of endoscopic resection for rectal NETs are still unclear. The

Advanced Science, EarlyView.This study identifies MZF1 as a core regulator of colon cancer via SnoN‐mediated TGF‐β suppression, proposes 10Panx Acetate as a targeted inhibitor, and validates MZF1/SnoN as prognostic markers for aggressive disease. ABSTRACT Colon cancer progression is associated with transcriptional and signaling abnormalities.

Are Small Rectal Neuroendocrine Tumors Safe? [PDF]
Intestinal Research, 2015 Neuroendocrine tumors (NETs) are slow-growing tumors with different biological and clinical characteristics. The incidence of NETs varies depending on the organ; however, the rectum is the most prevalent tumor site in the gastrointestinal system, accounting for 60-89% of all gastrointestinal NETs.1 These tumors are often found incidentally during ...
