PGD2/PTGDR2 Signaling Affects the Stemness of Gastric Cancer Stem Cells by Regulating Autophagy.
Comb Chem High Throughput Screen
January 2025
Department of Clinical Laboratory, The First Affiliated Hospital of Bengbu Medical University, Bengbu, China.
Background: Prostaglandin D2 (PGD2) can inhibit the development of gastric cancer (GC); however, its role in the autophagic death of GC stem cells (GCSCs) remains elusive. Therefore, this study aims to evaluate the mechanisms by which PGD2 regulates the stemness in GCSCs.
Methods: In this study, HGC27-derived GCSCs were employed to knock down PGD2 receptor 2 (PTGDR2).
Pharmacological modulation of Sigma-1 receptor ameliorates pathological neuroinflammation in rats with diabetic neuropathic pain via the AKT/GSK-3β/NF-κB pathway.

Diabetic neuropathic pain (DNP) is a common complication of diabetes mellitus (DM) and is characterized by spontaneous pain and neuroinflammation. The Sigma-1 receptor (Sig-1R) has been proposed as a target for analgesic development. It is an important receptor with anti-inflammatory properties and has been found to regulate DNP.

Scotland's Rural College Animal and Veterinary Sciences Research Group, Edinburgh, United Kingdom.
Approximately one in every 800 children is born with the severe aneuploid condition of Down Syndrome, a trisomy of chromosome 21. Low blood pressure (hypotension) is a common condition associated with DS and can have a significant impact on exercise tolerance and quality of life. Little is known about the factors driving this hypotensive phenotype and therefore therapeutic interventions are limited.

The Gynecology Department, Shanghai Key Laboratory of Maternal Fetal Medicine, Shanghai Institute of Maternal-Fetal Medicine and Gynecologic Oncology, Shanghai First Maternity and Infant Hospital, School of Medicine, Tongji University, Shanghai 200092, China. Electronic address:
Research Question: To investigate the underlying mechanisms driving the opposing effects of transforming growth factor-beta 1 (TGFβ1) on the proliferation of control (CESCs) and ectopic (EESCs) endometrial stromal cells.
Design: Cell proliferation assays (CCK-8 and colony formation) were employed to assess the effects of TGFβ1 on CESC and EESC proliferation. An immortalized human endometrial stromal cell line (HESC) was used to elucidate the mechanisms behind cytostatic effect of TGFβ1 and the potential role of cyclooxygenase (COX)-2 in mediating the modulation of TGFβ1 signaling.
Beta-sitosterol regulates PTGS1 to inhibit gastric cancer cell proliferation and angiogenesis.

January 2025
Department of Gastrointestinal Surgery, Shaoxing People's Hospital, Shaoxing, 312000, China. Electronic address:
Background: Gastric cancer (GC) is the third leading culprit of cancer-related deaths around the world. Beta-sitosterol (BS) is an important phytosterol that has been proven to have anti-proliferative effects on GC and other tumors. However, mechanisms and targets of BS in cancer are rarely explored.
