Opis:
Type 2 diabetes mellitus (T2DM) is a metabolic disease with a high risk of complications and mortality. Novel T2DM therapeutic interventions are needed to combat this disease. This study aimed to identify pathways involved in T2DM and investigate sesquiterpenoid compounds from Curcuma zanthorrhiza that could act as SIRT1 activators and NFκB inhibitors. Protein–protein interaction and bioactive compound analysis were conducted using the STRING and STITCH databases, respectively. Molecular docking was used to determine the compounds’ interactions with SIRT1 and NFκB, while toxicity prediction was performed using Protox II. The results showed that curcumin could act as a SIRT1 activator (4I5I, 4ZZJ, and 5BTR) and NFκB inhibitor on the p52 relB complex and p50–p65 heterodimer, while xanthorrhizol could function as an IκK inhibitor. The toxicity prediction indicated that the active compounds of C. zanthorrhiza were relatively nontoxic because beta-curcumene, curcumin, and xanthorrizol belong to toxicity classes 4 or 5. These findings suggest that the bioactive compounds of C. zanthorrhiza could be promising candidates for developing SIRT1 activators and NFκB inhibitors to combat T2DM.

Opis:
Calcyclin (S100A6) is believed to participate in cell cycle control. It was, however, unclear if its expression depends on p53, a key regulator of apoptosis and cell cycle. We therefore performed transcription regulation assays in HeLa cells and found that wild type p53 suppressed the S100A6 promoter up to 12-fold in a dose-dependent manner. In contrast, the well-characterized V143A, R175H, R249S, and L344A p53 mutants cloned from human cancers suppressed this promoter with a 6 to 9-fold lower efficiency. All the sites mediating the p53-dependent suppression were contained in the -167 to +134 fragment of the S100A6 promoter. Separate overexpression of either Sp1 or of NFκB only partially counteracted the p53 inhibitory effect on the S100A6 promoter, while simultaneous overexpression of both these transactivators resulted in a complete abolishment of the p53 inhibitory effect on this promoter. Sp1 and NFκB binding to the probes resembling their putative binding sites present in the S100A6 promoter was decreased in the presence of wild type p53. We propose that the suppression of S100A6 is yet another mechanism by which p53 inhibits proliferation. Insufficient suppression of this gene by p53 mutants could well be responsible for calcyclin overexpression and cell cycle deregulation observed in cancer tissues.
