Much of the current evidence is preclinical (cell and animal studies), and human data is still limited
Good sources of vitamin B12 include: meat salmon and cod milk and other dairy products eggs For vegans, some alternatives are: yeast extract (including Marmite) fortified breakfast cereals and soy products Diet is not usually the cause of vitamin B12 deficiency in the UK - the most common one is pernicious anaemia
5-Amino-1MQ Key Research Facts Chemical name: 5-Amino-1-Methylquinolinium (also abbreviated as 5A-1MQ or 5MQ) Target enzyme: Nicotinamide N-Methyltransferase (NNMT) Mechanism: Competitive inhibition of NNMT reduces 1-MNA production, preserves nicotinamide for NAD+ synthesis and SAM for epigenetic methylation Selectivity: High selectivity for NNMT does not inhibit related SAM-dependent methyltransferases or NAD+ salvage pathway enzymes Membrane permeability: High passive and active transport permeability confirmed in PAMPA and Caco-2 cell assays NNMT expression: Upregulated in obese adipose tissue, multiple cancer types, and aged skeletal muscle tissue contexts of primary research interest Downstream targets: NAD+ availability, SIRT1/SIRT3 activity, SAM-dependent epigenetic methylation, lipogenesis, energy expenditure Pre-clinical models: Diet-induced obese (DIO) mice, 3T3-L1 adipocyte cell models, aged mouse skeletal muscle models, HeLa cancer cell lines In vitro cell viability: No impact on cell viability at 10 M concentration in 3T3-L1 pre-adipocytes in published toxicity profiling What Does 5-Amino-1MQ Do in Research
From there, we will travel by bus for approximately 50 minutes north toward the city of Puno, enjoying the breathtaking landscapes of the Andean high plains
