M2 Macrophages, but Not M1 Macrophages, Support Megakaryopoiesis by Upregulating PI3K-AKT Pathway Activity

Aberrant bone marrow-M1/M2 MФ polarization, characterized by increased M1 MФs and decreased M2 MФs and accompanied by impaired megakaryopoiesis-supporting abilities, was found in patients with thrombocytopenia post-allotransplant.

Isorhapontigenin Ameliorates Cerebral Ischemia/Reperfusion Injury via Modulating Kinase Cε/Nrf2/HO-1 Signaling Pathway

Focal cerebral ischemia-reperfusion injury model and primary cortical neurons were established an oxygen-glucose deprivation injury model. Neuronal cell viability was determined by MTT assay. Western blot analysis was determined for protein expression.

Exosomal Linc-ROR Mediates Crosstalk between Cancer Cells and Adipocytes to Promote Tumor Growth in Pancreatic Cancer

The effects of conditioned medium collected from dedifferentiated adipocytes on pancreatic cancer cell proliferation, motility, metastasis and epithelial-mesenchymal transition (EMT) were evaluated by western blot analysis, colony forming, real-time cell analysis, 5-ethynyl-2’-deoxyuridine, immunofluorescence, Transwell and wound healing assays in vitro.

Apoptosis-Mediated Anticancer Activity in Prostate Cancer Cells of a Chestnut Honey (Castanea sativa L.) Quinoline–Pyrrolidine Gamma-Lactam Alkaloid

Scientists studied the in vitro inhibitory properties of the tryptophan-derived endogenous metabolite kynurenic acid and of the lactam form of 3–2′-pyrrilonidinyl-kynurenic acid, alkaloids usually present in combination in chestnut honey in two castration-resistant prostate cancer cell lines.
