Conversely, high oxidative stress can accelerate NAD+ degradation via the enzyme CD38, which consumes NAD+ as part of the inflammatory response

In addition, pathway analysis has shown that DNA replication pathway was significantly modified, and differential gene analysis revealed that colony stimulating factor 3 (CSF3), plasminogen activator, urokinase (PLAU), ubiquitin like with PHD and ring finger domains 1 (UHRF1), FOS like 1, AP-1 transcription factor subunit (FOSL1), IL1B, dual specificity phosphatase 6 (DUSP6), minichromosome maintenance complex component (MCM)2, cyclin D1 (CCND1), Wnt family member 7B (WNT7B), MCM5, MCL1 apoptosis regulator (MCL1), SH2B adaptor protein 3 (SH2B3), MCM3, heterogeneous nuclear ribonucleoprotein M (HNRNPM), and paralemmin 2 and A-kinase anchoring protein 2 fusion (PALM2AKAP2) were upregulated and activating transcription factor 4 (ATF4), farnesyl-diphosphate farnesyltransferase 1 (FDFT1), adenylate cyclase 8 (ADCY8), cytochrome P450 family 1 subfamily B member 1 (CYP1B1), epiregulin (EREG), family with sequence similarity 114 member A1 (FAM114A1), eukaryotic translation initiation factor 4A2 (EIF4A2), aldo-keto reductase family 1 member B (AKR1B1), mitogen-activated protein kinase 1 interacting protein 1 like (C14orf132), collagen type I alpha 2 chain (COL1A2), cyclin dependent kinase inhibitor 1 A (CDKN1A), aspartate beta-hydroxylase (ASPH), DEPP autophagy regulator 1 (DEPP1), aldo-keto reductase family 1 member C1 (AKR1C1), and DNA damage inducible transcript 4 (DDIT4) were downregulated in treated SPF mice when compared to the untreated mice [253]
