Description

The uppermost part of the pathway includes part of the general NAM salvage pathway in the cytosol as it is relevant to senescence-induced changes to NAD metabolism. In this pathway, NAD levels are maintained through recycling back to NAD from nicotinamide (NAM) and nicotinamide mononucleotide (NMN) (Braidy et al., 2019). The conversion from NAM to NMN is catalyzed by nicotinamide phosphoribosyltransferase (NAMPT), while the conversion from NMN to NAD is catalyzed by nicotinamide mononucleotide adenylyl transferases (NMNATs). Other sources, such as nicotinic acid (NA) and nicotinamid riboside (NR), are not shown here as they are not affected by senescence, at least from current research. OIS-specific interactions are highlighted in orange, while MiDAS-specific interactions are highlighted in purple. General interactions for both (or other senescent types) remain a black color.

The OIS pathway, induced by Ras singalling in this case, results in the upregulation of HMGA1, and stimulation of the NAMPT enzyme (Nacarelli et al., 2019). Resulting increased levels of NMN (the direct metabolite of NAMPT) translate to increased NAD levels, and a high NAD-NADH ratio. This leads to decreased ADP-ATP levels, which causes a decreased phosphorylated AMPK expression (Nacarelli et al., 2019). This interaction causes increased p38 and p65 activation, and increased NF-κB activity. The NF-κB signalling pathway has been known to play a key role in the promotion of the proinflammatory SASP (Freund et al., 2011). Furthermore, this is correlated with increased expression of interleukins IL1B, IL6 and IL8, all key factors in the proinflammatory wave of the SASP. In addition, Nacarelli et al. (2019) found that the proinflammatory environment created as a result of the increased NAD-NADH ratio leads to acceleration of cancer progression. NAMPT upregulation through HMGA1 also resulted in the expression of senescence markers SA-ß-gal, p16 and p21. The resulting phenotype from this high NAD-NADH ratio is a high proinflammatory SASP.

Malate is another important metabolite in redox reactions and in many senescence types, including OIS and MiDAS. Of interest to NAD metabolism is the malate-aspartate shuttle, where NADH is transferred from the cytosol to the mitochondrial matrix through malate dehydrogenase 1 (MDH1) (Lee et al., 2012). In senescence, levels of MDH1 decrease. On the other hand, decreased activity of MDH1 can induce a senescence response. This reduction in MDH1 activity results in a decreased cytosolic NAD-NADH. Lastly, this inhibition may result in loss of cell proliferation due to the requirement of aspartate synthesis in response to inhibition of the electron transport chain (Birsoy et al., 2015).
