The lactate-NAD axis activate cancer associated fibroblasts by downregulating p62 [Quantseq]

Project description:Reduced p62 levels are associated with the induction of the cancer-associated fibroblast (CAF) phenotype, which promotes tumorigenesis in vitro and in vivo through inflammation and metabolic reprogramming. However, how p62 is downregulated in the stroma fibroblasts by tumor cells to drive CAF activation is an unresolved central issue in the field. Here we show that tumor-secreted lactate downregulate p62 transcriptionally through a mechanism involving reduction of the NAD+/NADH ratio, which impaired poly(ADP-Ribose)-polymerase 1 (PARP1) activity. PARP1 inhibition blocked the poly(ADP-ribosyl)ation of the AP1 transcription factors, c-FOS and c-JUN, which is an obligate step for p62 downregulation. Importantly, restoring p62 levels in CAFs by NAD+ rendered CAFs less active. PARP inhibitors, such as Olaparib, mimicked lactate in the reduction of stromal p62 levels, as well as the subsequent stromal activation both in vitro and in vivo, which suggests that therapies utilizing Olaparib would benefit from strategies aimed at inhibiting CAF activity.

Identification of genes regulated by L-lactate and by DL-lactate in Lactobacillus plantarum

Project description:L. plantarum is known to possess an L-lactate inducible lactate racemase activity (Goffin et al. 2005. J. Bacteriol. 187:6750). In the present study, microarrays were used in order to identify all genes that are up-regulated by L-lactate, but not by a racemic mixture of D- and L-lactate. A mutant of L. plantarum NCIMB8826 deficient for NAD-dependent L-lactate activity (TF101; Ferain et al. 1994. 176:596), and thus producing no L-lactate, was grown in MRS medium at 28Â°C until mid-exponential phase (OD600nm 0.75). The culture was then divided into 3 sub-cultures. Optically pure sodium L-lactate (200 mM) was added to the first sub-culture (TF101 + L-lac 200 mM). An equimolar mixture of sodium D- and L-lactate (100 mM each) was added to the second sub-culture (TF101 + L/D-lac 200 mM). The third sub-culture was not treated (TF101; reference sample). The three sub-cultures were further incubated at 28Â°C for 1h30 (a time known to be sufficient for induction of lactate racemase activity by L-lactate). Cells were harvested by centrifugation. Microarray data were used ot identify genes that are specifically induced by L-lactate (comparison of TF101 with TF101 + L-lac 200 mM), but not by DL-lactate (comparison of TF101 with T101 + L/D-lac 200 mM). There are no biological replicates.
