Extracorporeal shock waves effectively suppress colorectal cancer proliferation and growth

ABSTRACT: Shock waves are widely used to treat various diseases and have numerous medical applications. In particular, extracorporeal shock waves (ESV) can substantially inhibit tumour growth. However, the therapeutic efficacy of ESV in colorectal cancer and its underlying mechanisms are not well understood. To address this gap in our knowledge, colorectal cancer cell lines HT29 and SW620 were used to generate xenograft mouse models and examined the therapeutic effects of a stepwise increase in ESV energy on tumour growth. In vivo, 60 mJ ESV significantly delayed xenograft growth compared with 120 and 240 mJ ESV, with no impact on body weight or hepatic and renal function. Transcriptome analysis revealed that 60 mJ ESV suppressed colorectal cancer cell proliferation and induced apoptosis and ferroptosis; these findings were further confirmed by immunohistochemical staining and western blotting. The in vitro study showed that ESV mechanistically suppressed cell proliferation and induced apoptosis and ferroptosis by activating the p53 signaling pathway. In conclusion, 60 mJ ESV substantially inhibited colorectal cancer growth by activating p53 pathway-related proliferation inhibition and cell death. These findings indicate that ESV therapy is a promising therapeutic strategy for colorectal cancer.

CAPG silencing promotes CRC cell apoptosis and ferroptosis via P53 pathway

Project description:Colorectal cancer (CRC) is the third most common cancer in the world and the second leading cause of cancer-related deaths. However, there are few effective therapeutic targets for colorectal cancer. Here, we report that Capping Actin Protein, Gelsolin Like (CAPG), a protein involved in actin related movement, is significantly overexpressed in human CRC tissues, and that expression levels are inversely correlated with overall survival. CAPG knockdown CRC cell lines inhibited cell proliferation, blocked cell cycle in G1 phase, increased apoptosis rate and promoted the occurrence of ferroptosis. RNA-seq data suggested that CAPG silencing promotes cell cycle arrest, apoptosis, and ferroptosis by activating the P53 pathway. Therefore, CAPG has potential to serve as a prognostic marker as well as a cancer therapy target in the future.

IGF2BP3 enhances ferroptosis resistance in colon cancer by stabilizing SLC7A11 mRNA and is regulated by miR-98-5p

Project description:Colorectal cancer (CRC) is one of the most prevalent malignancies worldwide, with increasing incidence and mortality rates. Resistance to cell death is a hallmark of cancer, and ferroptosis, a form of non-apoptotic cell death, has emerged as a critical factor in tumor suppression. The RNA-binding protein IGF2BP3, which plays a significant role in colon cancer progression, has been shown to modulate various oncogenic processes. However, its involvement in ferroptosis regulation in colon cancer remains largely unexplored. This study investigates the role of IGF2BP3 in ferroptosis regulation and its potential as a therapeutic target in colon cancer. Our data show that IGF2BP3 is upregulated in colon cancer tissues and correlates with poor prognosis. Knockdown of IGF2BP3 in colon cancer cell lines enhances sensitivity to ferroptosis induction, evidenced by increased reactive oxygen species (ROS) and malondialdehyde (MDA) levels, which are reversed by the ferroptosis inhibitor ferrostatin-1. Mechanistically, IGF2BP3 regulates ferroptosis by stabilizing SLC7A11 mRNA, a key ferroptosis regulator, through its interaction with the mRNA. Additionally, miR-98-5p directly targets IGF2BP3, enhancing ferroptosis sensitivity. In vivo studies confirm that IGF2BP3 knockdown suppresses tumor growth, highlighting its potential as a therapeutic target. Overall, our findings suggest that IGF2BP3 plays a pivotal role in regulating ferroptosis in colon cancer, offering new avenues for therapeutic strategies in colon cancer treatment.

TRIB3 inhibition by palbociclib sensitizes prostate cancer to ferroptosis via SOX2-mediated SLC7A11 downregulation

Project description:Palbociclib is a CDK4/6 inhibitor approved for the treatment of breast cancer by suppressing cell proliferation. However, monotherapy with palbociclib was discouraging in prostate cancer, calling for a mechanism-based effective therapy. In this study, we reported in prostate cancer that palbociclib is a potent sensitizer of ferroptosis, which is worked out by downregulating the expression of TRIB3, a gene highly expressed in prostate cancer. Specifically, TRIB3 knockdown augmented the response of prostate cancer cells to ferroptosis inducers, whereas, TRIB3 overexpression rescued prostate cancer cells from palbociclib-induced ferroptosis. Mechanistically, TRIB3 inhibition by palbociclib resulted in downregulation of SOX2, which subsequently led to compromised expression of SLC7A11, a cystine/glutamate antiporter that counteracts ferroptosis. Functionally, a combined treatment of palbociclib with ferroptosis inducer significantly suppressed prostate cancer growth in a xenograft tumor model. Together, these results uncover an essential role of TRIB3/SOX2/SLC7A11 axis in palbociclib-induced ferroptosis, suggesting palbociclib a promising targeted therapy in combine with ferroptosis induction for the treatment of prostate cancer.

Proteomic and phosphoproteomic analyses for HT-29

Project description:Metastatic BRAFV600E colorectal cancer (CRC) confers poor prognosis and run into a bottleneck in the current treatment strategies. To identify regulatory pathways independent of the MAPK pathway in BRAFV600E CRC, we performed CRISPR-Cas9 screening, and and find targeting glutathione peroxidase 4 (GPX4) remarkably overcome BRAF inhibitor (BRAFi) ± epidermal growth factor receptor (EGFR) inhibitor (EGFRi) resistance in BRAFV600E CRC. Specifically, BRAFi ± EGFRi induced GPX4 upregulated expression and antagonized ferroptosis. Moreover, polo-like kinase 1 (PLK1) substrate activation promoted PLK1 translocation to the nucleus, activating chromobox protein homolog 8 (CBX8) phosphorylation at Ser265, which induce GPX4 expression. Targeting PLK1 promoted BRAFi ± EGFRi inhibition and triggered ferroptosis in vitro, vivo, organoid, and patient-derived xenograft model. Collectively, we demonstrate a novel PLK1–CBX8–GPX4 signaling axis relaying the ferroptosis mechanism of therapeutic resistance operated independent of MAPK signaling and suggest a clinically actionable strategy to overcome BRAFi ± EGFRi resistance in BRAFV600E CRC.

Genome-wide RNAi Screening Identifies pseudouridine synthase DKC1 promotes CRC proliferation through regulating ribosomal proteins expression

Project description:Colorectal cancer (CRC) with high rate of mortality is one of the most commonly diagnosed cancers in worldwide. Advanced colorectal cancer is often accompanied by malignant proliferation of tumor cells. Further researches on colorectal cancer proliferation to find new targets and develop new therapeutic regimen are an important direction for colorectal cancer treatment. In this study, genome-wide RNAi screening was used to discover the essential genes associated with colorectal cancer cell proliferation. We found DKC1 (dyskerin pseudouridine synthase 1) promoted CRC proliferation through binding and modifying ribosomal proteins (RPL10A, RPL22L1, RPL34, RPS3) mRNA to increase the mRNAs stability and eventually increasing their expression. Besides, DKC1 is highly expressed in colorectal cancer and its aberrantly high expression is associated with poor prognosis of colorectal cancer patients. These results suggest that DKC1 could be a new therapeutic target for colorectal cancer.

Liver metastatic growth in colorectal cancer depends on PAD4 leading to modification of the extracellular matrix by citrullination

Project description:Colorectal cancer is one of the most frequently occurring malignancies and a major cause of cancer death. Distant metastases in this disease most commonly develop in the liver and are often untreatable. Here, we show that citrullination of the extracellular matrix (ECM) by cancer cell derived peptidylarginine deiminase 4 (PAD4) is essential for the growth of liver metastases. Citrullination of proteins, a post-translational conversion of arginine residues to citrulline, is well recognized in rheumatoid arthritis, but largely undocumented in cancer. PAD4, a key enzyme responsible for catalyzing citrullination, is produced by metastatic colorectal cancer cells and found at higher levels in human liver metastases than in normal liver. Functional significance for citrullination in metastatic growth was evident in murine models where inhibition of citrullination, either globally by pharmacologic inhibition of PADs or specifically in colorectal cancer cells by PAD4 knockdown substantially reduced liver metastatic burden. Additionally, citrullination of a key ECM component collagen type I led to greater adhesion and decreased migration of colorectal cancer cells along with increased expression of characteristic epithelial markers, suggesting a role for citrullination in promoting mesenchymal-to-epithelial transition (MET) and liver metastasis. Overall, our study revealed the potential for PAD4-dependant citrullination to drive the progression of liver metastasis. These data indicate that inhibition of citrullination could be exploited to prevent the development of liver metastases in colorectal cancer.

Mechanistic insights into anti-cancer properties of Curcumin and Andrographis in colorectal cancer

Project description:Colorectal cancer (CRC) remains the major leading cause of cancer-related deaths worldwide. The limitations of current chemotherapeutic drugs in CRC include their toxicity, side effects, and exorbitant costs. To assess these unmet needs in CRC treatment, several naturally occurring compounds, including Curcumin and Andrographis, have gained increasing attention due to their multi-targeted functionality and safety vs. conventional drugs. In the current study, we revealed that a combination of Curcumin and Andrographis exhibited superior anti-tumor effects by inhibiting cell proliferation, invasion, colony formation, and induction of apoptosis. Genomewide transcriptomic expression profiling analysis revealed that Curcumin and Andrographis activated the ferroptosis pathway.
