Expression Data from Ovarian Surface Kinome

ABSTRACT: The human kinome is incolved in multiple function in the life cycle of cells, and ther differntial expression in cacner suggests that protein kinases play an important role in tumor progression and proliferation. To delineate pathways that may be important for neoplastic change in women at high risk for ovarian cancer, we compared the expression signature of surface kinases in normal ovarian surface epithelium with ovarian epithelium from patients at high risk, and epithelial ovarian cancer using Affymetrix expresion array HG U133Plus2.

Expression Data from Ovarian Surface Kinome

To delineate pathways that may be important for neoplastic change in women at high risk for ovarian cancer, we compared the expression signature of surface kinases in normal ovarian surface epithelium with ovarian epithelium from patients at high risk, and epithelial ovarian cancer using Affymetrix expresion array HG U133Plus2. A total of 18 ovarian samples were collected. The number of samples and subjects for each group were: 5 cancer samples (5 subjects), 6 normal samples (4 patients) and 7 high-risk samples (5 subjects). After the initial inspection, one cancer sample (Sample 9) was excluded from the statistical analysis due to a poor RNA quality.

Adaptation of the Kinome Promotes Resistance to BET Bromodomain Inhibitors in Ovarian Cancer

Project description:Small molecule BET bromodomain inhibitors (BETi) are actively being pursued in clinical trials for the treatment of a variety of cancers, however, the mechanisms of resistance to targeted BET protein inhibitors remain poorly understood. Using a novel mass spectrometry approach that globally measures kinase signaling at the proteomic level, we evaluated the response of the kinome to targeted BET inhibitor treatment in a panel of BRD4-dependent ovarian carcinoma (OC) cell lines. Despite initial inhibitory effects of BETi, OC cells acquired resistance following sustained treatment with the BETi, JQ1. Through application of Multiplexed Inhibitor Beads (MIBs) and mass spectrometry, we demonstrate that BETi resistance is mediated by adaptive kinome reprogramming, where activation of compensatory pro-survival kinase networks overcomes BET protein inhibition. Furthermore, drug combinations blocking these kinases may prevent or delay the development of drug resistance and enhance the efficacy of BET inhibitor therapy. RNAseq was employed to identify changes in kinase RNA expression following short term (48h) or chronic (JQ1R) JQ1 treatment in three different ovarian cancer cell lines.

Intrinsic Resistance to MEK Inhibition Through BET Protein Mediated Kinome

Project description:Mutation or deletion of Neurofibromin (NF1), an inhibitor of RAS signaling, frequently occurs in epithelial ovarian cancer (EOC), supporting therapies that target downstream RAS effectors, such as the RAF-MEK-ERK pathway. However, no comprehensive studies have been carried out testing the efficacy of MEK inhibition in NF1-deficient EOC. Here, we performed a detailed characterization of MEK inhibition in NF1-deficient EOC cell lines using kinome profiling and RNA sequencing. Our studies showed MEK inhibitors were ineffective at providing durable growth inhibition in NF1-deficient cells due to kinome reprogramming. MEKi-mediated destabilization of FOSL1 resulted in induced expression of RTKs and their downstream RAF and PI3K signaling overcoming MEKi therapy. MEKi synthetic enhancement screens identified BRD2 and BRD4 as integral mediators of the MEKi-induced RTK signatures. Inhibition of BET proteins using BET bromodomain inhibitors (BETi) blocked MEKi-induced RTK reprogramming, indicating BRD2 and BRD4 represent promising therapeutic targets in combination with MEKi to block resistance due to kinome reprogramming in NF1-deficient EOC.

Kinome analysis of CD151 overexpressing Jurkat T cells

Project description:The effect of CD151 expression onto the kinome of Jurkat T cells was assessed using kinome analysis. CD151 was expressed in Jurkat T cells by retroviral transduction based on a pMSCV vector. Entrez Gene: 977 UniProtKB: P48509 Jurkat T cells were transduced with the MSCV-CD151 vector and successfully transduced cells were selected using puromycin. For the kinome array experiments 3 independent samples of Jurkat cells and three independent samples of J-CD151 cells were collected. To minimize unspecific background signals, lysates from Jurkat and J-CD151 T cells harvested at different growth stages, which were then pooled to provide one sample prior to loading on the Kinexus antibody microarrays.

Pecan kinome: classification and expression analysis of all protein kinases in Carya illinoinensis

Project description:Protein kinases (PKs) are involved in plant growth and stress responses, and constitute one of the largest superfamilies due to numerous gene duplications. However, limited PKs have been functionally described in pecan, an economically important nut tree. Here, the comprehensive identification, annotation and classification of the entire pecan kinome was reported. A total of 967 PK genes were identified from pecan genome, and further classified into 20 different groups and 121 subfamilies using the kinase domain sequences, which were verified by the phylogenetic analysis. The receptor-like kinase (RLK) group contained 565 members, which constituted the largest group. Gene duplication contributed to the expansion of pecan kinome, 169 duplication events including 285 PK genes were found, and Ka/Ks ratio revealed they experienced strong negative selection. GO functional analysis indicated majority PKs involved in molecular functions and biological processes. The RNA-Seq data of PK genes in pecan were further analyzed at subfamily level, and different PK subfamilies performed various expression patterns across different conditions or treatments, suggesting PK genes in pecan involved in multiple biological functions and stress responses. Taken together, this study provided insight into the expansion, evolution and function of pecan PKs. Our findings regarding expansion, expression and co-expression analyses could lay a good foundation for future research to understand the roles of pecan PKs, and find the key candidate genes more efficiently.
