Project description:Cancer stemness represents a major source of development and progression of colorectal cancer (CRC). c-Met critically contributes to CRC stemness, but how c-Met is activated in CRC remains elusive. We previously identified the lipolytic factor ABHD5 as an important tumour suppressor gene in CRC. Here, we show that loss of ABHD5 promotes c-Met activation to sustain CRC stemness in a non-canonical manner. Mechanistically, we demonstrate that ABHD5 interacts in the cytoplasm with the core subunit of the SET1A methyltransferase complex, DPY30, thereby inhibiting the nuclear translocation of DPY30 and activity of SET1A. In the absence of ABHD5, DPY30 translocates to the nucleus and supports SET1A-mediated methylation of YAP and histone H3, which sequesters YAP in the nucleus and increases chromatin accessibility to synergistically promote YAP-induced transcription of c-Met, thus promoting the stemness of CRC cells. This study reveals a novel role of ABHD5 in regulating histone/non-histone methylation and CRC stemness. We used microarrays to detail the gene expression of HCT116 colon cancer cell and ABHD5 knockdown HCT116 cell.

Project description:Activation of the inflammatory circuits occurs frequently in cancer cells. However the molecular details linking inflammation to transformation and progression are still unknown. In this study we report for the first time, that activation of the ETS factor ESE1 is a key event connecting inflammatory signaling with prostate cancer progression. We report that ESE1 is induced upon IL-1 beta stimulation by NFKB and mediates key transcriptional changes involving cell adhesion, migration and invasion. ESE1 activation in turn induces NFKB transcriptional activation and intranuclear translocation and mediates the transforming phenotypes linked to the activation of IL-1B. Transcriptional signatures and immunohistochemistry revealed that this ESE1-NFKB regulatory circuit also operates in prostate tumors, particularly in those with significant elevation of ESE1. Thus, ESE1 promotes an inflammatory feed forward loop positively leading to prostate cancer progression. Pharmacological NFKB inhibition reverted the transformed status of ESE1 cell lines providing a rationale for context-dependent therapeutic strategies in ESE1 activated tumors. These studies find a previously unrecognized link between ETS and activation of the NFKB pathway and open new avenues for prostate cancer treatment. Gene expression analysis of a control cell line (22Rv1-pcDNA3.1) and a testing cell lines (22Rv1-ESE1), with two replicates, with dye swap, performed for each sample.

Project description:Serine Peptidase Inhibitor, Kazal type 1 (SPINK1) overexpression represents the second-largest prostate cancer (PCa) subtype associated with increased risk of biochemical recurrence and poor prognosis. To determine the pathways regulated by SPINK1 in 22RV1 prostate cancer cells, we performed shRNA mediated knockdown of SPINK1 using lentiviral constructs. Scrambled shRNA was used as a control. pGIPZ constructs against SPINK1 (shSPINK1-1, shSPINK1-2, shSPINK1-3) and control shScrambled construct were purchased from Dharmacon.

Project description:Purpose: Even in last stage of metastatic castration-resistant prostate cancer, androgen receptor (AR) signaling remains active.To derive high metastatic prostate cancer (PCa), we labeled AR-positive but castration-resistant 22Rv1 PCa cells with luciferase gene (22Rv1-Luc2) and these cells were orthotopically implanted in mouse prostate for spontaneous progression. Methods: 2 × 10^5 of luciferase-expressing 22Rv1 cells (22Rv1-Luc2) cells were implanted in the anterior prostate of nude mice. After 12-14 weeks, the host mice were necropsied and the metastases from lumbar lymph nodes and primary tumors were dissected under laminar flow. Tumor tissues were minced using sterile scalpels and further digested with Collagenase D for 1 h. The lymph node metastatic cancer cells, named 22Rv1-M1, were orthotopically reimplanted in nude mice. At 12 weeks, the secondary metastases were isolated in the lumbar lymph nodes and designated as 22Rv1-M2 cells. Suspension of 1 × 10^6 22Rv1-M2 cells in DPBS was injected into nude mice through the tail vein, and mice developed metastases (22Rv1-M3) after 6 week. This procedure was repeated once to attain the 22Rv1-M4. Results: 22Rv1-derived metastatic cell lines exhibit increased in vitro and in vivo invasion activity as the progression from 22Rv1 to M4. Transcriptomic analysis of genome-wide gene expression in the M4 tumors reveal the unique gene expression profile compared to 22Rv1 tumors. Conclusions: Transcriptomic data provide the gene network for decoding the mechanism of PCa metastasis.
