Whole-exome sequencing of genomic DNA extracted from patient-derived melanoma cell lines resistant to vemurafenib (PLX).

Project description:Whole-exome sequencing was performed on DNA sample extracted from one melanoma cell line resistant to vemurafenib (BRAF V600E inhibitor). The aim of the experiment was to search for genetic alterations responsible for phenotypic diversity of melanoma cell lines reported at the level of cell morphology, activity of signaling pathways essential for melanoma development and progression, and resistance to targeted therapeutics.

Whole-exome sequencing of genomic DNA extracted from patient-derived melanoma cell lines resistant to vemurafenib (PLX) or trametinib (TRA)

Project description:Whole-exome sequencing was performed on DNA samples extracted from seven melanoma cell lines resistant to either vemurafenib (BRAF V600E inhibitor) or trametinib (MEK1/2 inhibitor). The aim of the experiment was to search for genetic alterations responsible for phenotypic diversity of melanoma cell lines reported at the level of cell morphology, activity of signaling pathways essential for melanoma development and progression, and resistance to targeted therapeutics.

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.

Whole-exome sequencing of genomic DNA extracted from patient-derived melanoma cell lines grown in vitro.

Project description:Whole-exome sequencing was performed on DNA samples extracted from eight patient-derived melanoma cell lines grown in vitro in serum-free EGF/bFGF-containing medium. The aim of the experiment was to search for genetic alterations responsible for phenotypic diversity of melanoma cell lines reported at the level of cell morphology, activity of signaling pathways essential for melanoma development and progression, and response to drugs.

Indolium 1 Exerts Activity against Vemurafenib-Resistant Melanoma In Vivo

Project description:The development of targeted therapies (Braf/MEK inhibitors) and immunotherapy have had a major impact on the treatment of melanoma. However, the majority of patients with advanced melanomas succumb to their disease. The mechanisms of resistance to both targeted therapies and immunotherapies are numerous and have been well-described. These include the alternative acti-vation of Braf/MEK signaling, novel compensating mutations in additional oncogenes, and loss of neoantigens. There has been limited development of small molecules that target alternative path-ways in melanoma in the last two decades. We have previously identified triphenylmethanes as a class that shows activity against a wide variety of tumors. We have synthesized a novel triphenyl-methane, indolium 1, and demonstrated its efficacy against an aggressive vemurafenib-resistant melanoma in vivo. Indolium 1 has a novel mechanism of action against melanoma, in that it results in induction of the tumor-suppressor EphA3. We believe that pre-IND studies are warranted for this novel compound, given its mechanism of action and ability to inhibit the growth of vemurafenib resistant melanoma in vivo

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.

Time-series RNA-seq experiment performed on 10 melanoma cell lines treated with BRAF inhibitor vemurafenib.

Project description:BRAF targeted drug vemurafenib have shown very good clinical benefit in melanoma patient containing BRAF V600E mutation. However, resistance always occurs in patient. Early stage of the resistance development require the tumor cell adapted to the targeted drug. We are trying to study the kinetic of melanoma cell adaptation towards vemurafenib. 10 melanoma cell lines with BRAF mutation are treated with targeted therapy vemurafenib. RNA-seq samples are collected after drug treatment for different time (day3 and day21) to compare with DMSO-treated control samples for each cell line. Except innate resistant cell line M381, all other cell lines shows inhibition of proliferation. However, a small cluster of cell lines (M397, M229 and M263) shows some other unique transcriptomic change. For cell line M397, M229 and M263, we also collected the RNA-seq data for long-term (73day/90day) drug treatment condition where the cells developed resistance to vemurafenib treatment. Dedifferentiation is enriched in these unique transcriptomic change within these 3 cell lines. Similar cell state dedifferentiation phenomenon is also reported to cause resistance towards immunotherpay where the resistant de-differentiated melanoma cells are induced by TNF which is secreted by tumor-infiltrating T cells. We also treat our cultured melanoma cells with TNF and collected the treated sample for RNA-seq experiment.
