Abstract The rising incidence of colorectal cancer (CRC) poses significant healthcare challenges. This study explored the therapeutic potential combined curcumin (CUR) and metformin (MET) treatment in CRC models. Our findings indicate that combination (COMB) effectively downregulates expression divalent metal transporter‐1 (DMT‐1), leading to a reduction cell proliferation aligned with suppression pAKT/mTOR/Cyclin D1 signaling pathway. COMB increased reactive oxygen species (ROS) production, triggering activation NRF2/KEAP1 pathway elicits an antioxidant response manage oxidative stress lines.

To date, metformin remains the first-line oral glucose-lowering drug used for treatment of type 2 diabetes thanks to its well-established long-term safety and efficacy profile. Indeed, is most widely insulin-sensitizing agent, being prescribed more than 100 million people worldwide, including patients with prediabetes, insulin resistance, polycystic ovary syndrome. However, over last decades several observational studies meta-analyses have reported a significant association between therapy an increased prevalence vitamin B12 deficiency. Of note, evidence suggests that high-dose impairs status. Vitamin (also referred as cobalamin) water-soluble mainly obtained from animal-sourced foods.

Water-soluble B vitamins, mainly obtained through dietary intake of fruits, vegetables, grains, and dairy products, act as co-factors in various biochemical processes, including DNA synthesis, repair, methylation, energy metabolism. These vitamins include B1 (Thiamine), B2 (Riboflavin), B3 (Niacin), B5 (Pantothenic Acid), B6 (Pyridoxine), B7 (Biotin), B9 (Folate), B12 (Cobalamin). Recent studies have shown that besides their fundamental physiological roles, influence oncogenic metabolic pathways, glycolysis (Warburg effect), mitochondrial function, nucleotide biosynthesis.

Background. Studies have demonstrated that patients with diabetes mellitus who receive metformin a lower risk of developing Parkinson’s disease (PD). However, studies also suggested may increase the PD. In this study, we investigated whether use was associated PD in type 2 (T2DM). Methods. population-based cross-sectional T2DM diagnosed between 2001 and 2018 were enrolled. We categorized these as users or nonusers. Participants below 50 years old excluded. Two models employed to evaluate associations exposure intensity after 3 5 follow-up. Results. Patients received <300 cumulative defined daily doses (cDDD) those <10 DDD/month had respective odds ratios (ORs) for 0.88 (95% confidence interval [CI] = 0.83−0.94) 0.87 CI 0.81−0.93) 3-year 5-year follow-up, such ORs 0.94 0.90−0.98) 0.93 0.89−0.98). ≥300 cDDD used ≥10 experienced no neuroprotective effects years.
