The values are presented as the means ± SEMs, n = 3. * P < 0.05, ** P < 0.01, ns means not significant. g Model that summarizes our findings on the role of NSD1 in regulating Sox9 directly and indirectly. On the one hand, NSD1 can directly promote Sox9 expression by regulating the levels of H3K36me1/2 in the Sox9 promoter region. On the other hand, NSD1 directly binds to the promoter region of Hif1α , activating Hif1α transcription and ultimately promoting Sox9 expression
