$Menin induces nuclear localization of YBX1 and activates HKDC1 transcription (A) Immunoblotting of cytoplasmic and nuclear fractions shows that Menin over-expression (Menin-OE) markedly increases nuclear YBX1 in PL45 and BxPC-3 cells compared with the negative control (NC); GAPDH and Histone H3 serve as cytoplasmic and nuclear loading controls, respectively. (B) Immunofluorescence imaging confirms the enhanced nuclear accumulation of YBX1 (red) following Menin-OE, with nuclei counter-stained by DAPI (blue); scale bars, 200 μm. (C) Cycloheximide (CHX) chase assays (0–8 h) reveal that Menin-OE does not affect YBX1 protein stability in either cell line (LaminB1 loading control). (D) FLAG immunoprecipitation of nuclear extracts demonstrates a physical association between Flag-tagged Menin and endogenous YBX1 in PL45 and BxPC-3 cells, with LaminB1 as the input control. (E) Schematic of HKDC1-promoter luciferase reporters containing a wild-type (WT) or mutated (Mut) YBX1-binding motif. (F) Dual-luciferase assays in HEK-293 cells show that YBX1 activates the WT reporter but not the Mut reporter. (G) In PL45 and BxPC-3 cells, Menin-OE and YBX1 co-expression synergistically enhance WT-reporter activity, whereas mutation of the YBX1 site abolishes this effect. (H) ChIP-qPCR confirms increased recruitment of YBX1 to the HKDC1 promoter upon Menin-OE. (I) YBX1 over-expression alone serves as a positive control. (J) Combined Menin-OE and YBX1-OE further augment YBX1 binding relative to vector or IgG controls. Quantitative data are presented as mean ± SD ( n = 3); ∗∗∗ p < 0.001 versus the indicated control.$

TWIST1 contributed to proliferation in PDAC cells. A . TWIST1, PKM2 and HK2 protein were significantly expressed in PL45, MIA-PACA-1, CFPAL-1 and PANC-1 cells. B . Knockdown of TWIST1 in TWISCFPAL-1 cell line. C . over-expression of TWIST1 in PANC-1 cell line. D . Red fluorescence represented EDU positive, which could be used as a representative of cell proliferation activity. Blue represented the nucleus. The magnification was 200 times. Cell proliferation was reduced by treatment with shRNA against TWIST1 and was promoted by over-expression of TWIST1. E . Clone formation number: knockdown TWIST1 inhibited cell cloning, while over-expression played a role in promoting cell cloning
