Hypoxic Tumor-Derived Exosomal miR-199a-3p Promote Gastric Cancer Metastasis via MAP3K4.

Proximal gastrectomy is more frequently recommended for early upper gastric cancer and Siewert II gastroesophageal junction cancer less than 4 cm in length. After proximal gastrectomy, the anatomical structure of the gastroesophageal junction can be destroyed, and the anti-reflux effect of the cardia is lost. In recent years, as various anti-reflux reconstructions have been developed, some functions of the stomach are retained, and serious reflux esophagitis is avoided after proximal gastrectomy.

Thirdhand Smoke May Promote Lung Adenocarcinoma Development through HN1.

Thirdhand smoke (THS) refers to residual tobacco smoking pollutants that can be adsorbed to indoor surfaces and dust and persist for years after active smoking. THS-related chemicals such as N-nitrosonornicotine (NNN) and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) are tobacco-specific lung carcinogens that involved in lung cancer development and progression. In this study, we computed the differentially expressed genes (DEGs) between THS and paired control samples.
