N2 - Excessive apoptosis of intervertebral disc cells, namely nucleus pulposus (NP) cells, results in decreased cell density and extracellular matrix (ECM) catabolism, hence leading to intervertebral disc degeneration (IVDD). As a cell model in the present study, a commercially available human NP cell line was utilized. Long noncoding RNAs and microRNAs may regulate the proliferation or apoptosis of human NP cells, hence exerting a significant influence on the occurrence of IVDD. KLF3-AS1 was discovered to be abnormally downregulated in IVDD tissues. Overexpression of KLF3-AS1 enhanced NP cell viability, prevented cell apoptosis, boosted ECM synthesis, and lowered MMP-13 and ADAMTS4 levels. ZBTB20 and KLF3-AS1 were co-expressed in IVDD; ZBTB20 overexpression had similar effects on NP cells, ECM production, and MMP-13 and ADAMTS4 levels as KLF3-AS1 overexpression. miR-10a-3p may target KLF3-AS1 and ZBTB20 and inhibit the expression of ZBTB20. Inhibition of miR-10a-3p enhanced NP cell viability, reduced apoptosis, and enhanced ECM synthesis. KLF3-AS1 overexpression increased ZBTB20 expression, whereas miR-10a-3p overexpression decreased ZBTB20 expression; miR-10a-3p overexpression reduced the effects of KLF3-AS1 on ZBTB20. Overexpression of miR-10a-3p consistently decreased the effects of KLF3-AS1 overexpression on NP cell survival, apoptosis, and ECM synthesis. In conclusion, KLF3-AS1 overexpression may ameliorate degenerative NP cell alterations through the miR-10a-3p/ZBTB20 axis.
