Asiaticoside promoted ferroptosis and suppressed immune escape in gastric cancer cells by downregulating the Wnt/β-catenin pathway.

Background: Our previous study has revealed that asiaticoside (AC) promotes endoplasmic reticulum stress and antagonizes proliferation and migration of gastric cancer (GC) via miR-635/HMGA1 axis. However, the effect and mechanism of AC on other progressions of GC, such as ferroptosis and immune escape, are still unknown.

Methods: AGS and HGC27 cells were incubated with 1, 2 and 4 μM of AC for 24 h.

A novel curcumin derivative CL-6 exerts antitumor effect in human gastric cancer cells by inducing apoptosis through Hippo-YAP signaling pathway.

Purpose: Gastric carcinoma is the second most frequently diagnosed cancer and leading cause of cancer death in China. As a new generation of cancer therapeutic drug, CL-6, a curcumin derivative, shows better bioavailability than curcumin, which has shown anticancer effects in gastric cancer (GC). However, whether CL-6 shows similar activities in GC has not been examined.

Nrf2-miR-129-3p-mTOR Axis Controls an miRNA Regulatory Network Involved in HDACi-Induced Autophagy.

Histone deacetylase inhibitors (HDACis) are the recommended treatment for many solid tumors; however, resistance is a major clinical obstacle for their efficacy. High levels of the transcription factor nuclear factor erythroid 2 like-2 (Nrf2) in cancer cells suggest a vital role in chemoresistance, and regulation of autophagy is one mechanism by which Nrf2 mediates chemoresistance. Although the molecular mechanisms underlying this activity are unclear, understanding them may ultimately improve therapeutic outcomes following HDACi treatment.

The characteristics and pivotal roles of triggering receptor expressed on myeloid cells-1 in autoimmune diseases.

Triggering receptor expressed on myeloid cells-1 (TREM-1) engagement can directly trigger inflammation or amplify an inflammatory response by synergizing with TLRs or NLRs. Autoimmune diseases are a family of chronic systemic inflammatory disorders. The pivotal role of TREM-1 in inflammation makes it important to explore its immunological effects in autoimmune diseases.

Inhibitory effect of isavuconazole, ketoconazole, and voriconazole on the pharmacokinetics of methadone in vivo and in vitro.

The aim of this study was to investigate the possible effect of orally administered isavuconazole, ketoconazole, or voriconazole on the pharmacokinetics of methadone in rats. Twenty Sprague-Dawley (SD) rats were divided randomly into four groups: Group A (control), group B (5 mg/kg isavuconazole), group C (5 mg/kg ketoconazole), and group D (5 mg/kg voriconazole). A single dose of methadone was administrated half an hour later.
