Depicts MTHFR variant activity For example, an individual who is heterozygous at both C677T (C/T) and A1298C (A/C), known as a compound heterozygote, is expected to exhibit a 55% decrease in MTHFR enzymatic activity (35% activity due to the presence of one T allele at C677T and 20% activity due to the presence of one C allele at A1298C = 55%)
Several technical reasons may explain our distinctive findings, including differences in the microbiome sampling site, the limited n per group, singly housing mice, or the use of highly similar lean, Western, and high-fat diets which systematically exchanged fat content with carbohydrate content

Further investigation showed that CPs first reduce the level of skin oxidation, inhibit the expression of the key transcription factor AP-1 (c-Jun and c-Fos), then activate the TGF-/Smad signaling pathway to promote collagen synthesis, inhibit the expression of MMP-1/3 to inhibit collagen degradation, and inhibit skin inflammation to alleviate skin aging in mice
