Project description:This project aimed to explore novel anticancer therapeutics from products of parasite since several data related to benefits from the T. spiralis infection have been documented. We validated antitumor activity of T. spiralis infective larval extract and extricate the parasite-derived-antitumor peptide. We found that larval extract exerted antitumor activity to three types of carcinoma cells including hepatocellular carcinoma HepG2, ovarian cancer SK-OV-3, and lung adenocarcinoma A549. Interestingly, it displayed the most antitumor effect to HepG2 cells. Using proteomic and bioinformatic approaches, three putative anticancer peptides were identified from T. spiralis infective larval extract. One of these peptides showed a dose-dependent-anti-HepG2 effect by inducing ROS accumulation, leading to inhibition of the cell proliferation. Our data indicate potential application of the larval extract-derived antitumor peptide as a complementary agent for human hepatoma treatment and highlight a positive aspect of parasite apart from its deleterious effect.

Project description:Reactive oxygen species (ROS) are by-products of metabolism of oxygen and they play an important role in normal homeostasis and cell signaling, as well as in the initiation of diseases including cancer when their production is upregulated. Thus, it is imperative to understand the cellular and molecular basis by which ROS impact on various biological and pathological processes. Here, we identified 2-oxindole, a tryptophan derivative, was a major catabolic product in hydrogen peroxide-treated cell culture medium. We used 2-oxindole to study its role in regulating AhR signaling and tryptophan metabolic pathways. We found that 2-oxindole significantly increased the activity of AhR, leading to enhanced expression of its downstream targets including cytochrome P450 genes.

Project description:Verteporfin (VP) inhibts colon cancer growth in vivo and in cell lines by inducing high molecular weight oligomerization of proteins. The antitumor effect of VP is independent of its YAP inhibitor activity. Tumor hypoxia contributes partly to antitumor effect of VP by impairing clearance of VP-induced high molecular weight aggregates.

Project description:Colorectal cancer remains a significant health threat, with its incidence continuously rising, underscoring the urgent need for the development of new therapeutic agents. In our previous research, we identified 7A, a derivative of Neratinib, as having pronounced antitumor activity. However, its specific effects and mechanisms in colorectal cancer have not been thoroughly investigated. Therefore, this study employed in vivo and in vitro experiments, utilizing techniques such as RNA sequencing, Western blotting, and PCR, to provide a comprehensive analysis of 7A's mechanism of action in colorectal cancer. The results indicate that 7A induces DNA damage and activates the P53 pathway, thereby promoting apoptosis in colorectal cancer cells. Additionally, 7A treatment significantly reduced angiogenesis and tumor weight. Our findings suggest that 7A, a Neratinib derivative, holds promise as a novel candidate for colorectal cancer therapy.

Project description:As pyrazole and its derivatives have a wide range of biological activities, including anticancer activity, the design of novel pyrazole derivatives has emerged as an important research field. This study describes a novel pyrazole derivative that exerts antitumor and radiosensitizing activities in breast cancer both in vitro and in vivo. We synthesized a novel pyrazole compound N,N-dimethyl-N'-(3-(1-(4-(trifluoromethyl)phenyl)-1H-pyrazol-4-yl)phenyl)azanesulfonamide (PCW-1001) and showed that it inhibited several oncogenic properties of breast cancer both in vitro and in vivo. PCW-1001 induced apoptosis in several breast cancer cell lines. Transcriptome analysis of PCW-1001-treated cells showed that it regulated the DNA damage response, suggesting its potential use in radiotherapy. Indeed, PCW-1001 enhanced the radiation sensitivity of breast cancer cells by modulating the expression of DNA damage response genes. Therefore, our data describe a novel pyrazole compound, PCW-1001, with antitumor and radiosensitizer activities in breast cancer.

Project description:Cancer therapy resistance, whether pre-existing or arising upon acquisition of de novo mutations and via non-genetic adaptation, is still a clinical challenge. Multiple anticancer drugs are thought to cause cell death via increasing mitochondrial ROS which are a bioproduct of oxidative phosphorylation. However, when properly titrated, ROS can also promote cancer cell adaptation. In keeping with this, upregulation of mitochondrial respiration coupled with high ROS-scavenging capacity is a characteristic shared by drug-tolerant cells in several cancers. Translational fidelity in the mitochondria and in the cytosol is essential for cell fitness and thus oxidative damage to the ribosomes should be prevented at all costs. While mechanisms for recognizing and repairing such damage exist in the cytoplasm, the status within mitochondria remains unclear. By performing Ascorbate PEroXidase (APEX)-proximity ligation assay directed to the mitochondrial matrix followed by isolation and sequencing of RNA associated to mitochondrial proteins, we identified the nuclear-encoded lncRNA ROSALIND as an interacting partner of ribosomes. ROSALIND is upregulated in recurrent tumours and its expression can discriminate between responders and non-responders to immune checkpoint blockade in a melanoma cohort of patients. Featuring an unusually high G content, ROSALIND serves as a substrate for oxidation. Consequently, inhibiting ROSALIND leads to an increase in ROS and protein oxidation, resulting in severe mitochondrial respiration defects. This, in turn, impairs melanoma cell viability and increases immunogenicity both in vitro and ex vivo in preclinical humanized cancer models. These findings underscore the role of ROSALIND as a novel ROS buffering system, safeguarding mitochondrial translation from oxidative stress, and shed light on potential therapeutic strategies for overcoming cancer therapy resistance.
