Expression data from BRAFV600E A375 melanoma cells treated with vehicle or vemurafenib

Project description:Vemurafenib is a BRAF inhibitor with specificity for the most common BRAF mutant encountered in melanomas (BRAFV600E). Vemurafenib suppresses the proliferation of BRAF mutant human melanoma cells by suppressing downstream activation of the MEK/ERK mitogen activated protein kinases. We used microarrays to examine the transcriptional response of a vemurafenib-sensitive BRAFV600E human melanoma cell line (A375) to vemurafenib in order to further delineate the mechanisms by which BRAFV600E drives cell proliferation and energy metabolism in human melanoma. BRAFV600E A375 human melanoma cells were treated with vehicle (0.1% DMSO) or 10 uM vemurafenib for 24 h after which total RNA was extracted. Cells were prepared and RNA was extracted in 3 separate batches (three different cell stocks on three separate days) providing three independent replicates (n=3). Paired replicates (prepared from the same stock of cells on the same day) are denoted by A, B and C.

Synergy from Gene Expression and Network Mining (SynGeNet) method predicts genotype-specific synergistic drug combinations in melanoma

Project description:Using our computational method SynGeNet to evaluate genomic and transcriptomic data characterizing four major genomic subtypes of melanoma, we selected the top ranked drug combination for BRAF-mutation melanoma for subsequent validaiton. Here we present drug-induced gene expression data from the BRAF-mutant A375 melanoma cell line in response to four treatment conditions: vehicle control (DMSO), vemurafenib alone, tretinoin (ATRA) alone and vemurafenib+tretinoin combination.

Vemurafenib induces a noncanonical senescence-associated secretory phenotype in melanoma cells which promotes vemurafenib resistance

Project description:To explore the characteristics of senescent melanoma cells induced by vemurafenib or cisplatin, melanoma A375 cells were treated with vemurafenib and cisplatin, respectively. The senescent phenotypes were verified by β-gal staining, EdU assay, cell morphology and the senescence-related pathways. RNA-seq was performed to explore the differentially expressed genes in the senescent cells induced by vemurafenib or cisplatin.

A four-arm study of A375 melanoma cell line-derived xenograft tumors in NSG mice treated with Vemurafenib and CB839

Project description:Melanoma is a rare but deadly form of skin cancer, which is often treated with BRAF inhibitors such as Vemurafenib (referred to as PLX4032). Whilst Vemurafenib prolongs the survival of patients, BRAF inhibitor resistance inevitably occurs in most cases. Previous studies demonstrated that metabolic rewiring occurs in BRAF inhibitor resistance and causes dependence on glutamine. To investigate whether this vulnerability could be exploited with clinically relevant drugs, we used the BRAF inhibitor, Vemurafenib, and the glutaminase imhibitor, CB839 to treat A375-derived melanoma xenografted tumors. We showed that whilst CB839 did not significantly affect the growth of A375-derived tumors compared to those given a vehicle, the addition of CB839 to Vemurafenib treatment had a significant anti-tumor effect. Tumors were taken at the endpoint (Max tumor length 15mm) from the 6 mice in each treatment group and cut into fragments and stored in RNAlater for RNAseq analysis. RNA extraction was performed on 1-3 fragments per tumor to make up 200-300mg of tissue.

Gene expression of the A375 melanoma cell line treated with RAF inhibitors Vemurafenib and time-course with EGF stimulation during Vemurafenib RAF inhibitor treatment alone or with the MEK inhibitor Cobimetinib

Project description:We treated for 24 hours the BRAF-V600E melanoma cell line A375 with 7 doses of the RAF inhibitor Vemurafenib and, in a second experimental desing, we treated for 24 hours the BRAF-V600E melanoma cell line A375 with Vemurafenib (1 uM) alone or in combination with the MEK inhibitor Cobimetinib (1 uM) and subsequently stimulated with EGF in a time-course of 7 time points for up to 8 hours (0, 0.5, 1, 2, 3, 4, 8 hours).
