Cedrol, a sesquiterpene alcohol, isolated from has been reported to inhibit minichromosome maintenance (MCM) proteins as cancer biomarkers in human lung cancer in vitro. In the present study, we investigated the anti-cancer activity of cedrol in vitro and in vivo using human colorectal cancer HT29 cells and a human colorectal tumor xenograft model. Cedrol inhibited MCM protein expression and cell growth in HT29 cells, which are associated with G1 arrest and the induction of apoptosis.

Proteins related to DNA replication have been proposed as cancer biomarkers and targets for anticancer agents. Among them, minichromosome maintenance (MCM) proteins, often overexpressed in various cancer cells, are recognized both as notable biomarkers for cancer diagnosis and as targets for cancer treatment. Here, we investigated the activity of cedrol, a single compound isolated from , in reducing the expression of MCM proteins in human lung carcinoma A549 cells.

Article Synopsis
  • Researchers isolated and studied the α- and β- subunits of a chaperonin (ApCpnA and ApCpnB) from the microorganism Aeropyrum pernix K1, confirming their expression in E. coli through SDS-PAGE analysis.
  • The purified chaperonin subunits were found to hydrolyze ATP and other nucleotides (CTP, GTP, UTP) effectively at high temperatures, with their activities peaking at 80°C.
  • ApCpnA and ApCpnB also provided protection against heat-induced aggregation and inactivation of enzymes like citrate synthase and alcohol dehydrogenase, with their protective effects enhanced by the addition of ATP or CTP, and potassium ions

In the present study, we examined the gastroprotective effect of selenium against ethanol-induced gastric mucosal lesions in rats. The gastric mucosal lesions were produced by oral administration with various concentrations of ethanol for three days, and 80% ethanol treatment was determined to be the optimal condition for induction of gastric damage. To identify the protective effect of selenium on ethanol-induced gastric damage, various doses of selenium were given as pretreatment for three days, and then gastric damage was induced by 80% ethanol treatment.

Adipocyte differentiation is strongly associated with obesity, which causes metabolic disorders. In this study, we investigated the inhibitory effects of widdrol on 3T3- L1 preadipocyte growth and differentiation. Widdrol decreased lipid droplet accumulation and down-regulated adipogenic transcription factors such as C/EBPalpha, C/EBPbeta, and PPARgamma.
