Background: Mechanisms driving cerebrovascular decline during Alzheimer's disease and related dementias (ADRD) are poorly understood. Methylenetetrahydrofolate reductase (MTHFR) is an enzyme in the folate/methionine pathway. Variants in MTHFR, notably 677C>T, are associated with ADRD.

Alzheimers Dement
December 2024
Department of Neurosurgery, Clinical Neuroscience Research Center, Tulane University School of Medicine, New Orleans, LA, USA.
Background: Increasing evidence suggests that SARS-CoV-2 infection may lead to early onset and aggravation of pre-existing vascular dementia and Alzheimer's disease. Methylene tetrahydrofolate reductase (Mthfr) is a critical enzyme in folate metabolism, also required for optimal brain function. Mthfr deficient mice display cognitive impairments and neurovascular deficits and polymorphisms in MTHFR increases dementia risk.

The tumorigenesis of colorectal cancer (CRC) often follows the normal-adenoma-carcinoma (N-A-C) sequence. However, the molecular mechanisms underlying colorectal adenoma carcinogenesis remain largely unknown. Here, we analyzed transcriptomic profile changes in normal, advanced adenoma, and carcinoma tissues from patients with CRC, revealing that glutamic-pyruvic transaminase 1 () in colorectal tissues was down-regulated during the N-A-C process and correlated with poor CRC prognosis.

Background/aim: Hallux valgus (HV) is the most common deformity of the forefoot. Although HV has been strongly associated with a family history, its genetic underpinnings remain unclear. Few studies have examined the relationship between folic acid metabolism, which is critical in normal bone development, and HV.

Introduction: Acute kidney injury (AKI) is linked to high rates of mortality and morbidity worldwide thereby posing a major public health problem. Evidences suggest that ferroptosis is the primary cause of AKI, while inhibition of monoamine oxidase A(MAOA) and 5-hydroxytryptamine were recognized as the defender of ferroptosis. Curcumin (Cur) is a natural polyphenol and the main bioactive compound of , which has been found nephroprotection in AKI.
