Article Title: Epigenetically silenced KAT2B suppresses de novo lipogenesis through destroying HDAC5/LSD1 complex assembly in renal cell carcinoma
doi: 10.1016/j.jare.2025.08.007
Figure Lengend Snippet: KAT2B suppressed lipogenesis through FASN (A) Key rate-limiting enzymes in de novo lipogenesis and their expression levels in ccRCC and pRCC using TCGA-KIRC and TCGA-KIRP databases. Red squares and blue squares represented genes whose expression were up-regulated or down-regulated in tumors. (B) Schematic diagram for screening key lipid synthesis factors downstream of KAT2B. (C) Statistical analysis of oil red O stainging in 786O cells following knockdown of 10 key lipogenesis factors (n = 3). (D-E) Representative IHC staining for FASN in RCC cohort and statistical analysis (n = 80, paired t‐test). (F-G) After KAT2B knockdown in 786O and ACHN cells, the mRNA and protein expression of FASN was observed. (H) The cell growth curves of A498 and Caki-1 cells with KAT2B and/or FASN overexpression were determined by CCK8 assays (n = 4, independent‐samples t‐test). (I) The relative TG levels in A498 and Caki-1 cells with KAT2B and/or FASN overexpression (n = 4, independent‐samples t‐test). (J) Representative images of oil red O staining of A498 and Caki-1 cells with KAT2B and/or FASN overexpression and statistical analysis (n = 3, independent‐samples t‐test). Data were analyzed by unpaired t test (G), paired t test (E), one-way ANOVA (H, I, J) or two-way ANOVA (C).
Article Snippet: The HK‐2, 293 T, A549, PC9, T47D, MCF7, A498, Caki-1, OSRC-2, 786O, 769P and ACHN cell lines were obtained from the American Type Culture Collection (ATCC, USA) and were cultivated under proper conditions according to the manufacturer’s protocols.
