A new 1,2,3-triazole-indirubin hybrid suppresses tumor growth and pulmonary metastasis by mitigating the HGF/c-MET axis in hepatocellular carcinoma.

Introduction: Hepatocellular carcinoma (HCC) is a fatal cancer that is often diagnosed at the advanced stages which limits the available therapeutic options. The interaction of HGF with c-MET (a receptor tyrosine kinase) results in the activation of c-MET which subsequently triggers the PI3K/Akt/mTOR axis. Overexpression of c-MET in HCC tissues has been demonstrated to contribute to tumor progression and metastasis.

Oxazine drug-seed induces paraptosis and apoptosis through reactive oxygen species/JNK pathway in human breast cancer cells.

Small molecule-driven JNK activation has been found to induce apoptosis and paraptosis in cancer cells. Herein pharmacological effects of synthetic oxazine (4aS, 7aS)-3-((4-(4‑chloro-2-fluorophenyl)piperazin-1-yl)methyl)-4-phenyl-4, 4a, 5, 6, 7, 7a-hexahydrocyclopenta[e] [1,2]oxazine (FPPO; BSO-07) on JNK-driven apoptosis and paraptosis has been demonstrated in human breast cancer (BC) MDA-MB231 and MCF-7 cells respectively. BSO-07 imparted significant cytotoxicity in BC cells, induced activation of JNK, and increased intracellular reactive oxygen species (ROS) levels.

Efficacy of personalized repetitive transcranial magnetic stimulation based on functional reserve to enhance ambulatory function in patients with Parkinson's disease: study protocol for a randomized controlled trial.

Background: Repetitive transcranial magnetic stimulation (rTMS) is one of the non-invasive brain stimulations that modulate cortical excitability through magnetic pulses. However, the effects of rTMS on Parkinson's disease (PD) have yielded mixed results, influenced by factors including various rTMS stimulation parameters as well as the clinical characteristics of patients with PD. There is no clear evidence regarding which patients should be applied with which parameters of rTMS.
