Research Details:
AMP is a product of the resynthesis of ATP from ADP via adenylate kinase, and is the primary signal for activation of AMP-Activated Protein Kinase (AMPK) in response to depleted ATP stores (Hardie, 2004; Adams, Chen, Van Denderen, Morton, Parker, Witters, & Kemp, 2004). This makes AMP the cornerstone of increased ATP production, but its activation of AMPK goes beyond simply upregulating ATP levels, as it is critical in mitochondrial health and cellular response to exercise, and has even been described as an ‘exercise mimetic’ (Herzig, & Shaw, 2018; Chen, Stephens, Murthy, Canny, Hargreaves, Witters, & McConell, 2003; Narkar, Downes, Ruth, Embler, Wang, Banayo, & Kang, 2008). Interestingly, the average human at any one time contains 250g of ATP, but over the course of the day will produce over 60kg of ATP, as a result of the constant use and recycling of the same 250g (Pizzorno, 2014). This suggests that small changes to instantaneous AMP and ATP stores could significantly alter total daily energy availability.
AMPK is the primary cellular sensor for energy usage, and behaves as a detector for the AMP/ATP ratio, upregulating its activity in response to increased AMP or decreased ATP (Hardie, Ross, & Hawley, 2012). AMPK also takes cellular glucose concentration as an input, whereby insufficient glucose encourages formation of the active AXIN-AMPK-LKB1 complex (Zhang, Guo, Zhang, Lin, Yin, Peng, & Li, 2013).
AMPK activation exhibits a swathe of beneficial effects, including upregulation of the expression of genes controlling glucose uptake, fatty acid oxidation, and mitochondrial biogenesis. Many of these effects in skeletal muscle are the direct result of AMPK’s induction of PGC-1α, the master regulator for mitochondrial biogenesis and energy homeostasis. This in turn results in increased expression of genes such as GLUT1 and GLUT4, the glucose channels which enable cellular glucose uptake and metabolism (Barnes, Ingram, Porras, Barros, Hudson, Fryer, & Baldwin, 2002; Jäger, Handschin, Pierre, & Spiegelman, 2007). AMPK activation also increases cellular NAD+ levels, in turn upregulating SIRT1, which has been implicated in increased lifespan, lipolysis in fatty tissues, and insulin sensitivity (Cantó, Gerhart-Hines, Feige, Lagouge, Noriega, Milne, & Auwerx, 2009; Imai, & Guarente, 2014; Picard, Kurtev, Chung, Topark-Ngarm, Senawong, de Oliveira, & Guarente, 2004; Sun, Zhang, Ge, Yan, Chen, Shi, & Zhai, 2007).
AMPK is also strongly linked to cellular responses to hypoxic conditions, such as upregulation of glycolysis (Emerling, Weinberg, Snyder, Burgess, Mutlu, Viollet, & Chandel, 2009; Marsin, Bertrand, Rider, Deprez, Beauloye, Vincent, & Hue, 2000).
Other protective effects of the activation of AMPK by AMP-5 include protection against neurodegeneration (Li, Zeng, Viollet, Ronnett, & McCullough, 2007), against renal cysts (Takiar, Nishio, Seo-Mayer, King, Li, Zhang, & Caplan, 2011) and modulation of reactive oxygen species to protect against diabetes (Dugan, You, Ali, Diamond-Stanic, Miyamoto, DeCleves, & Nguyen, 2013; Hinchy, Gruszczyk, Willows, Navaratnam, Hall, Bates, & Murphy, 2018).
