Transcriptional analysis of human IL-23R mediated apoptosis in human cervical cancer cells in vitro

Project description:We found that IL-23R mediated HeLa cell apoptosis by characterizing the functional domains responsible for this event. For exploring apoptotic pathways activated by IL-23R, the altered transcriptomic profiles in responding to IL-23R over-expression was also revealed by RNAseq analysis.

Molecular Targeting of 15-Lipoxygenase-1 (15-LOX-1) for Apoptosis Induction in Human Colorectal Cancers

Project description:Primary Objective: * To determine whether celecoxib downregulates GATA-6 expression to upregulate 15-LOX-1 expression and induce apoptosis in human rectal tumors, researchers will measure GATA-6 and 15-LOX-1 expression, 13-S-HODE levels, and apoptosis rates in normal and colorectal polyp epithelial tissues before and after 6 months of celecoxib treatment of patients with familial adenomatous polyposis (FAP).

Antitumor Activity of Galaxamide Involved in Cell Apoptosis and Stemness by Inhibiting Wnt/β-catenin Pathway in Cervical Cancer.

Project description:Background and Purpose: Our previous work reported that galaxamide, a cyclopeptide extracted from the seaweed Galaxaura filamentosa, showed antiproliferative activity against HeLa cells by MTT assay. However, the therapeutic effects in vivo and potential mechanisms to eliminate cervical cancer cells remain unknown. Experimental Approach: HeLa cells were obtained as a cervical carcinoma in vitro model. The growth-inhibitory effects of galaxamide in HeLa cells and xenograft mouse models were investigated. RNA-seq was employed to analyse the main target of galaxamide in HeLa cells. Immunostaining, qRT‒PCR and Western blotting were applied to test the pharmacological effects in vitro and in vivo. Key Results: Galaxamide significantly inhibited cell growth, colony formation, migration, and invasion and induced cell apoptosis by inhibiting the Wnt signalling pathway in HeLa cells. RNA sequencing revealed that galaxamide regulated stemness via the Wnt6 signalling pathway in HeLa cells. By analysing The Cancer Genome Atlas database (TCGA), Wnt6 was found to be negatively/positively correlated with stemness- and apoptosis-related genes in human cervical cancer. Cancer stem-like cells (CSCs) isolated and enriched from HeLa cells demonstrated elevated Wnt6 and β-catenin genes compared with nonstem HeLa cells. After galaxamide treatment, CSCs showed abrogation of sphere-forming ability, along with inhibition of stemness-related and Wnt pathway genes. Galaxamide treatment was accompanied by the induction of apoptosis in HeLa cells, which was consistent with the results in BALB/c nude mice. Conclusion and Implications: Our results provide preclinical evidence that suppression of stemness by downregulating the Wnt signalling pathway is the molecular mechanism by which galaxamide effectively inhibits cell growth and induces apoptosis in cervical cancer cells.

Host-defence peptides caerin 1.1 and 1.9 stimulate TNF-alpha-dependent apoptosis in human cervical cancer HeLa cells

Project description:TNFα pathway has been recognised as one of the most important signalling pathways characterising molecules with anti-cancer activity, due to it closely relates to cell survival as well as apoptosis. Isolated from the glandular secretion of Australian tree frogs, the genus Litoria, host-defence caerin peptides have been previously shown to have multiple biological activities, including anti-proliferation of several cancer cell lines, though the mechanism remains unclear. In this study, we used multiple immunoassays, confocal microscopy in conjunction with TMT-labelling quantitative proteomics to investigate the anti-proliferative activities of caerin 1.1 and 1.9 against cervical cancer HeLa cells. The proteins of cells and cell growth environment post the treatments were comparatively analysed, respectively. We found that both caerin 1.1 and 1.9 highly inhibited HeLa cell proliferation with a significant additive effect. The PPI analysis confirmed that the interactions among the significantly regulated proteins were highly intensive. Besides translation, folding and localisation of proteins and RNA processing, apoptosis process was significantly enriched post the treatments. The apoptosis process was resulted by TNFα signalling, confirmed by the elevated levels of CASP3 and CASP9. Moreover, EGFR1 and androgen receptor pathways appeared inhibited. The activation of TCR pathway derived from the quantitation results further implies the likelihood of recruiting more T cells to the cell growth environment post the treatment and more sensitive to T cell mediated killing of Hela cells.

Proteomics of Human Cervical Mucus Plugs

Project description:Preterm birth is a leading cause of neonatal mortality and lacks an effective therapy. Ascending microbial infections from the lower genital tract lead to infection of the placenta, amniotic fluid and fetus causing preterm birth or stillbirth. Directly in the path of an ascending infection is the cervical mucus plug (CMP), a dense mucoid structure in the cervical canal with potential antimicrobial properties. In this study, we aimed to define the components of CMP responsible for antimicrobial activity against a common lower genital tract organism associated with preterm birth and stillbirths, namely Group B Streptococcus (GBS). Using a quantitative proteomic approach, we identified antimicrobial factors in CMPs that were collected from healthy human pregnancies. This study aims to provide new insight into how the human CMP may limit ascending bacterial infection.

Whole transcriptome sequencing in human cervical adenocarcinoma and normal cervical tissues

Project description:mRNA, lncRNA, and miRNA signatures were identified to discriminate cervical adenocarcinoma from normal cervix by whole transcriptome sequencing. We confirmed the RNA-seq data in another cohort of clinical cervical tissue samples by qRT-PCR.We demonstrated that miR-192-5p/HNF1A-AS1/VIL1 panel could accurately discriminates adenocarcinoma from normal cervix. Moreover,we also identified the circRNA expression profiles in cervical adenocarcinoma tissues and explored the function roles and mechanisms of circular RNA circEYA1 and circSPIDR in cervical adenocarcinoma cells.
