Phosphoproteomics guides low dose drug combination of cisplatin and silmitasertib against concurrent chemoradiation resistant cervical cancer

Project description:Cervical cancer is one of the leading causes of cancer related deaths among females. Due to proper screening programmes, most of the cervical cancer cases are presented in the locally advanced stage of the disease. Concurrent chemoradiotherapy (CCRT) is the standard treatment for locally advanced cervical cancer. However, resistance to CCRT limit the success of the treatment regimen. In this study, we investigated the altered phosphoproteome of CCRT resistant and sensitive cohort using Mass spectrometry-based proteomics. We carried out phosphoproteomic analysis of treatment naïve cervical cancer patients whose response to CCRT is recorded. The Phosphoproteomic analysis revealed kinases and the pathways associated with CCRT resistance in cervical cancer patients.

DNA copy number data from the CE01 clinical study

Project description:Patients with cervical cancer were treated with external beam radiotherapy (EBRT) at a dose of 45Gy in 25 fractions over five weeks, with weekly cisplatin. Biopsies were taken pre-, during and post-treatment and analysed for copy number changes. Cervical cancer patients were treated with chemoradiotherapy and disease response was followed by array CGH profiling.

Differential gene expression between skin and cervix induced by the E7 oncoprotein in a transgenic mouse model

Project description:HPV16 E7 oncoprotein expression in K14E7 transgenic mice induces cervical cancer after 6 months of treatment with the co-carcinogen 17M-NM-2-estradiol. In untreated mice, E7 also induces skin tumors late in life, albeit at low penetrance. These findings indicate that E7 alters cellular functions in cervix and skin so as to predispose these organs to tumorigenesis. Using microarrays, we determined the global genes expression profile in cervical and skin tissue of young adult K14E7 transgenic mice without estrogen treatment. In these tissues, the E7 oncoprotein altered the transcriptional pattern of genes involved in several biological processes, including immune response, intracellular signaling cascades, cell adhesion, cell migration, development, cell cycle, growth, response to wounding and regulation of apoptosis. Among the E7-dysregulated genes were ones not previously known to be involved in cervical neoplasia, including DMBT1, GLI1 and 17M-NM-2HSD2 in cervix and MMP2, 12, 14, 19 and 27 in skin. The experiment consists of a total of 24 samples to evaluate the mRNA expression profiles in 4 different groups: skin biopsy of transgenic mice K14E7, cervix biopsy of transgenic mice K14E7, skin biopsy of FVB/N control virgin mice and cervix biopsy of FVB/N control virgin mice. Each group has 6 samples that had been processed in 3 pools of two samples (biological replicates) for a total of 6 samples for each condition.

Interactome of activated BAX in Senescent Cells.

Project description:We aimed to identify the interactome of activated BAX in the mitochondria of senescent cells. Our goal was to understand which factors can directly mediate the formation of BAX pores in senescent cells.

Developmental vascular regression is regulated by a Wnt/b-catenin, MYC, P21 (CDKN1A) pathway that controls cell proliferation and cell death

Project description:Normal development requires tight regulation of cell proliferation and cell death. Here, we investigated these control mechanisms in the hyaloid vessels, a temporary vascular network in the mammalian eye that requires a Wnt/β-catenin response for scheduled regression. Transcriptome analysis of the postnatal day 5 mouse hyaloid showed expression of several Wnt pathway proteins. We investigated whether the hyaloid Wnt response was linked to the oncogene Myc, and the cyclin-dependent kinase inhibitor P21 (CDKN1A), both established regulators of cell cycle progression and cell death. Our analysis showed that the Wnt pathway coreceptors LRP5 and LRP6 have overlapping activities mediating the Wnt/β-catenin signaling in hyaloid vascular endothelial cells (VECs). We also showed that both Myc and Cdkn1a are downstream of the Wnt response and are required for hyaloid regression but for different reasons. Conditional deletion of Myc in VECs suppressed both proliferation and cell death. By contrast, conditional deletion of Cdkn1a resulted in VEC over-proliferation that countered the effects of cell death on regression. When combined with analysis of MYC, and P21 protein levels, this analysis suggests that a Wnt/β-catenin, MYC-P21 pathway regulates scheduled hyaloid vessel regression.

Gene expression changes in cervical motor neuron transcriptomes after loss of Hox5 transcription factors

Project description:The goal of this study was to identify potential Hox5 target genes in cervical motor neurons (C3-C6) using unbiased genomic screens (RNA-seq). We examined expression changes independently of motor neuron cell death by deleting the pro-apoptotic gene Bax in both control and experimental mice.

Prediction of sensitivity of rectal cancer cells in response to preoperative chemoradiotherapy by DNA microarray analysis of gene expression profiles.

Project description:Samples were prospectively collected during colonoscopic examination from 46 rectal cancer patients before starting preoperative chemoradiotherapy. The expression profiles were determined using Affymetrix Human Genome U133 Plus 2.0 arrays. Comparison between the sample groups allow to identify a set of discriminating genes that can be used for prediction of the response to radiotherapy in rectal cancer. Specimens from 46 rectal cancer patients who approved to receive preoperative chemoradiotherapy were studied. We prospectively collected biopsy specimens during colonoscopic examination from rectal cancer before starting preoperative chemoradiotherapy. Specimens from tumors were snap-frozen in liquid nitrogen and stored at -80 C until use. Paralleled tumor specimens were formalin fixed and paraffin embedded for histologic examination and other specimens were used for RNA extraction. RNA was extracted from tumor tissue using frozen samples. The patients provided written, informed consent to the collection of specimens, and the local Ethics Committee approved the study protocol. All patients received a total dose of 50.4 Gy of radiation, UFT(300-500mg/day) and LV (75mg/day) and underwent standardized curative resection, following an interval of 4 weeks after chemoradiotherapy.

Gene expression analysis of SCG sympathetic neurons with loss of Egr3

Project description:The transcription factor Egr3 has been shown to have a cell autonomous role in sympathetic nervous system (SNS) development. We utilized microarray analysis to identify potential downstream target genes deregulated with loss of Egr3. Both conditions were in the null Bax background to prevent apoptosis and therefore mitigate identification of apoptosis related genes. Our analysis identified genes involved in biological processes that were expected such as SNS development and axonogenesis as well as those that were unexpected such as dendritogenesis and axon guidance. This led us to investigate whether Egr3 is important in these unexpected biological processes within sympathetic neurons. Total RNA was obtained from superior cervical ganglion (SCG) dissected from P0 mice with the genotype of Egr3+/+; Bax-/- or Egr3-/-; Bax-/-. Each genotype had 3 samples each.
