Gastric cancer is the fourth most common malignancy and the third leading cause of cancer-related deaths worldwide. This study aimed to investigate the expression patterns, biological roles, and underlying mechanisms of microRNA-147 (miR-147) in gastric cancer. The present study demonstrated that miR-147 was significantly upregulated in gastric cancer tissues and cell lines. Downregulation of miR-147 decreased cell proliferation and enhanced the chemosensitivity of gastric cancer cells to 5-fluorouracil (5-FU) through the cell apoptosis pathway. In addition, phosphatase and tensin homolog (PTEN) was mechanically identified as the direct target of miR-147 in gastric cancer. PTEN knockdown reversed the effects of miR-147 downregulation on the proliferation, chemosensitivity, and 5-FU-induced apoptosis of gastric cancer cells. Moreover, miR-147 regulated the PI3K/AKT signaling pathway in gastric cancer by targeting PTEN. In conclusion, miR-147 suppressed the proliferation and enhanced the chemosensitivity of gastric cancer cells to 5-FU by promoting cell apoptosis through directly targeting PTEN and regulating the PI3K/AKT signaling pathway. This study provides important insight into the molecular mechanism that underlies the chemoresistance of gastric cancer cells. The results of this study could aid the development of a novel therapeutic strategy for gastric cancer.

Background: Gastric cancer (GC) is a prevalent malignancy with a substantial health burden and high mortality rate, despite advances in prevention, early detection, and treatment. Compared with the global average, Asia, notably China, reports disproportionately high GC incidences. The disease often progresses asymptomatically in the early stages, leading to delayed diagnosis and compromised outcomes.

Background: Owing to the absence of specific symptoms in early-stage gastric cancer, most patients are diagnosed at intermediate or advanced stages. As a result, treatment often shifts from surgery to other therapies, with chemotherapy and targeted therapies being the primary options for advanced gastric cancer treatment.
Aim: To investigate both treatment efficacy and immune modulation.

Background: Efficacy of eradication regimens in (Hp) infection is commonly reported with proton pump inhibitors (PPIs). In patients with corpus atrophic gastritis, characterized by impaired acid secretion, PPI treatment is questionable.
Objectives: The current study aimed to assess in clinical practice the tolerability and eradication rate of modified eradication regimens without PPI as first-line treatment in patients with histologically Hp-positive corpus atrophic gastritis.
