Article Title: CPT1A mediates the succinylation of SP5 which activates transcription of PDPK1 to promote the viability and glycolysis of prostate cancer cells

doi: 10.1080/15384047.2024.2329372

Figure Lengend Snippet: CPT1A is highly expressed in PCa tissues and cell lines. (a) GEPIA was used to analyze the dysregulated expression of CPT1A in PCa. PRAD: prostate adenocarcinoma. T: tumor and N: normal. (b) The expression of CPT1A in PCa tissues and the normal tissues was detected by qPCR. (c) The expression of CPT1A in PCa cell lines and the prostate epithelial cell line (PNT2) was detected by qPCR. * p <.05 in (A). ** p < .01, *** p < .001 vs PNT2 group.

Article Snippet: HEK-293T cells, normal human epithelial prostate PNT2 cells and the PCa cell lines including DU145, LNCap, 22Rv1 and VCaP were purchased from ATCC (USA) and were maintained in Dulbecco’s modified eagle medium containing 10% fetal bovine serum and 1% penicillin/streptomycin (all from Thermo Fisher Scientific, USA).

Figure Lengend Snippet: Metastatic PCa cells promote OC activity and induce pathological phenotype. (a) Representative IVIS image showing PCa‐transplanted xenograft mice ( N = 3) on Day 35. Tumours in the hind limbs were evaluated based on the photon radiance of cancer cell bioluminescence. (b) Representative images of HE‐, osteoclastic and osteoblastic marker TRAP/ALP‐ and cancer‐specific marker LAT1 stained sections of bone metastatic sites in the xenografted mouse which was shown in (a). All images were obtained with an all‐in‐one fluorescence microscope using a 4x objective for low‐, 10x objective for middle‐, and 40x objective for high‐magnification. Black arrowheads indicate the tumour metastatic site, and white arrowheads indicate OCs. The metastatic tumour developed in the femur. Scale bar indicates 300 µm. (c) Schematic images of the transwell co‐culture system for obtaining cancer‐associated OCs (CAOCs) and normal osteoclasts (NOCs). OC precursor RAW 264.7 cells were grown into mature OCs in the lower compartment. Mature OCs with osteolytic PC3M cells (OCP cells) and mature OCs with osteoblastic C4‐2B cells (OCC cells) were used as CAOCs. Mature OCs with blank transwells (OC cells) and mature OCs with PNT2 (OCN cells) were prepared as control NOCs. (d) Schematic images of transwell co‐culture for observing CAOCs and NOCs. (e) Representative TRAP staining images of each OC. Bars represent 100 µm. ( f) Representative TRAP staining images of each OCs treated with denosumab at the concentration of 10 µg/mL. Bars represent 100 µm.

Article Snippet: PC3M, C4‐2B, and the immortalized normal human prostatic epithelial cell line PNT2 (DS Pharma Biomedical Co., Ltd, Osaka, Japan) were cultured in RPMI 1640 medium (Gibco, Thermo Fisher Scientific, Waltham, MA, USA) supplemented with 10%‐inactivated foetal bovine serum (FBS, Gibco, Thermo Fisher Scientific) and 1% antibiotic‐antimycotic (AA) solution (Gibco, Thermo Fisher Scientific) at 37 °C in atmosphere of 95% air and 5% CO 2 .

Figure Lengend Snippet: Inflammatory‐related signalling pathways are enhanced in CAOCs. (a) Schematic protocol of co‐culture and gene expression analysis of CAOCs. (b) Heat map showing differentially expressed genes (CAOC vs. OCN, change >2.0‐fold and p < 0.05) in RAW 264.7, co‐cultured with PCa cells ( n = 2) in the presence of RANKL. (c) The number of differentially expressed genes in mature OCs co‐cultured with PC3M cells (OCP cells) or C4‐2B cells (OCC cells) compared to that in OCN cells co‐cultured with PNT2 cells (OCN cells). (d) PCA of gene expression of each type of OCs. (e) Pathway analysis of selected genes that were significantly upregulated in CAOCs compared to OCN cells. (f) GSEA of CAOC versus NOC, highlighting pro‐inflammatory phenotypes. NES: normalized enrichment score. p value was calculated using GSEA. (g) Expression levels of Il‐1b , Casp1 , Il‐6 and Tnf in gene sets of inflammation‐related genes. OC co‐cultured with a blank insert (OC cells) or PNT2 (OCN cells), and OC co‐cultured with PC3M (OCP cells) or C4‐2B (OCC cells) are presented. The blue, green, yellow and red dots represent the OC, OCN, OCP and OCC cell data, respectively.
