Project description:WW-domain-containing oxidoreductase (WWOX) is the tumour suppressor gene from the common fragile site FRA16D, whose altered expression has been observed in tumours of various origins. Its suppressive role and influence on basic cellular processes such as proliferation and apoptosis have been confirmed in many in vitro and in vivo studies. Moreover, its protein is thought to take part in the regulation of tissue morphogenesis and cell differentiation. However, its role in colon cancer formation remains unclear. The aim of this study was to characterize the influence of WWOX on the process of colon cancerogenesis, the basic features of the cancer cell and its expression profiles. Multiple biological tests, microarray experiments and quantitative reverse transcriptase (RT)-PCR were performed on two colon cancer cell lines, HT29 and SW480, which differ in morphology, expression of differentiation markers, migratory characteristics and metastasis potential and which represent negative (HT29) and low (SW480) WWOX expression levels. The cell lines were subjected to retroviral transfection, inducting WWOX overexpression. WWOX was found to have diverse effects on proliferation, apoptosis and the adhesion potential of modified cell lines. Our observations suggest that in the HT29 colon cancer cell line, increased expression of WWOX may result in the transition of cancer cells into a more normal colon epithelium phenotype, while in SW480, WWOX demonstrated well-known tumour suppressor properties. Our results also suggest that WWOX does not behave as classical tumour suppressor gene, and its influence on cell functioning is more global and complicated.

Project description:The WWOX gene is a tumor suppressor probably involved in regulation of cell cycle and apoptosis and downregulated in variety of cancer types.However, its role in colon cancerogenesis is unknown. The aim of this study was to characterize how WWOX may be involved in colon cancerogenesis or cancer progression, how it influences the basic cancer cell features and modifies cell expression profile.Our observations suggest that in HT29 colon cancer cell line increased expression of WWOX may result in transition of cancer cells into more normal- like colon epithelium phenotype, on the other hand in SW480 WWOX revealed the well-known tumour suppressor properties. However, as the colon cancer is very heterogeneous disease, obtained discrepancies may reflect the known differences between cell lines and cancerogenesis pathway, which they undergone.

SW480 colon cancer cells were stably transfected with WWOX cDNA. SW480 cells transfected with an empty vector served as a control. Total mRNA was isolated to look for gene-expression differences induced by the WWOX overexpression.

Project description:Aerobic glycolysis is a pivotal hallmark of cancers, including colorectal cancer. Evidence shows glycolytic enzymes are regulated by post-translational modifications (PTMs), thereby affecting the Warburg effect and reprograming cancer metabolism. Lysine lactylation is a PTM reported in 2019 in histones. In this study, we identified protein lactylation in FHC cells and SW480 colon cancer cells through mass spectrometry. Totally, 637 lysine lactylation sites in 444 proteins were identified in FHC and SW480 cells. Lactylated proteins were enriched in the glycolysis pathway, and we identified lactylation sites in phosphofructokinase, platelet (PFKP) lysine 688 and aldolase A (ALDOA) lysine 147. We also showed that PFKP lactylation directly attenuated enzyme activity. Collectively, our study presented a resource to investigate proteome-wide lactylation in SW480 cells and found PFKP lactylation led to activity inhibition, indicating that lactic acid and lactylated PFKP may form a negative feedback pathway in glycolysis and lactic acid production.

Project description:The contributions of phosphorylation-mediated signaling networks to colon cancer metastasis are poorly defined. To interrogate constitutive signaling alterations in cancer progression, the global phosphoproteomes of patient-matched SW480 (primary colon tumor origin) and SW620 (lymph node metastasis) cell lines were compared with TiO2 and immobilized metal affinity chromatography phosphopeptide enrichment followed by liquid chromatography-tandem mass spectrometry. Network analysis of the significantly altered phosphosites revealed differential regulation in cellular adhesion, mitosis, and messenger RNA translational machinery. Messenger RNA biogenesis and splicing, transport through the nuclear pores, initiation of translation, and stability and degradation were also affected. Although alterations in these processes have been associated with oncogenic transformation, control of messenger RNA stability has typically not been associated with cancer progression. Notably, the single phosphosite with the greatest relative change in SW620 cells was Ser2 on eukaryotic translation initiation factor 2 subunit 2, suggesting that SW620 cells translate faster or with greater efficiency than SW480 cells. These broad changes in the regulation of translation also occur without overexpression of eukaryotic translation initiation factor 4E. The findings suggest that metastatic cells exhibit constitutive changes to the phosphoproteome, and that messenger RNA stability and translational efficiency may be important targets of deregulation during cancer progression.
