There is a lack of research on the combined effects of genetic variations (specifically CD36 SNPs-rs1761667 and rs1527483), dietary food habits (vegetarian or not), and the salivary environment on obesity and taste sensitivity, especially in the Indian population. The current study aims to better understand the relationship between impaired taste perception, fat consumption, higher BMI and obesity development by examining the combined association between CD36 SNPs, oleic acid (OA) detection threshold, and food habits among Indian participants. Furthermore, the relationship between oral fatty acid (FAs) sensitivity and taste physiology factors linked to inflammation and salivary proteins was considered.

Parkinson's disease (PD) is an advancing age-associated progressive brain disorder which has various diverse factors, among them mitochondrial dysfunction involves in dopaminergic (DA) degeneration. Aging causes a rise in mitochondrial abnormalities which leads to structural and functional modifications in neuronal activity and cell death in PD. This ends in deterioration of mitochondrial function, mitochondrial alterations, mitochondrial DNA copy number (mtDNA CN) and oxidative phosphorylation (OXPHOS) capacity.

Previously we have reported the isoliensinine (ISO) potentates the therapeutic potential of cisplatin in cisplatin resistant colorectal cancer stem cells. The present study evaluates the chemo-sensitizing potential of the combinatorial regimen of ISO and Paclitaxcel (PTX) on multidrug-resistant (MDR)-HCT-15 cells to reduce the dose requirement of both ISO and PTX. The results of the present study suggest that treatment with the combinatorial regimen of ISO and PTX enhanced the cytotoxic effect with resultant increase in apoptosis in MDR-HCT-15 cells as evident from the altered cellular morphology, G2/M cell cycle arrest, propidium iodide uptake, Annexin V, increased intracellular Ca accumulation, decreased mitochondrial membrane potential, diminished ATP production, PARP-1 cleavage, altered expression of ERK1/2, and apoptotic proteins.
