Project description:The Hippo Pathway is a critical signaling network that regulates organ size and cellular proliferation in metazoans. The transcriptional enhanced associate domain (TEAD) family of transcription factors serve as the receptors for the downstream effectors of the Hippo pathway, YAP and TAZ, to upregulate expression of multiple genes involved in proliferation, cell-fate determination, polarity, and survival1. Recent work revealed that TEAD proteins are palmitoylated at a conserved cysteine with the lipid tail extending into the hydrophobic core of the protein2. Mutagenic and covalent modulation of the palmitoylation site disrupts Hippo signaling2,3; however, an understanding of why TEAD proteins require this seemingly essential modification and the therapeutic implications of modulating TEAD palmitoylation has remained elusive. Here we report the identification and optimization of a potent pan-TEAD small molecule that binds the TEAD lipid pocket (LP), blocks palmitoylation, and dysregulates TEAD activity in multiple cancer cell lines. Cellular and biochemical data interrogating the mechanism of action for our compound reveal TEAD palmitoylation to function as a checkpoint that regulates TEAD homeostasis. We show that bypassing this checkpoint with a small molecule increases TEAD protein levels thereby decreasing the ability of YAP/TAZ to activate downstream target gene transcription in a dominant-negative manner. Our study demonstrates a new role for lipidation in protein signaling and establishes the TEAD LP as a bona fide therapeutic site for modulation of the Hippo Pathway.

Project description:A total of 432 genes were found to be differentially expressed in M1SF370 bacterial population internalized in Detroit 562 human pharyngeal cells when compared with the same strain incubated in the absence of Detroit 562 cells. While most of them (349/432 i.e. 80.8%) were up regulated, 83 genes were down regulated contributing to 19.2% of the total differentiated genes. The major contributor of the latter category was phage-related genes (35 genes). Almost ¼ of these genes (106) belonged to a category of Unknown or possible predicted function. Most notably, up-regulated genes belonged to amino acid transport , cell division, cell envelope biogenesis, DNA replication correlated well with up-regulated 67 genes belonged to translation and ribosomal structure. Further, up-regulation of 12/15 virulence-related genes indicated that human host cell internalized bacteria are highly virulent as compared to laboratory grown culture in test-tubes.

Further, up-regulation of 12/15 virulence-related genes indicated that human host cell internalized bacteria are highly virulent as compared to laboratory grown culture in test-tubes. S. pyogenes strain type M1 SF370 (wild-type) was procured from ATCC (ATCC 700294). Detroit 562 pharyngeal cells were obtained from ATCC and maintained in MEM with 10% FBS in humidified CO2-incubator. Purified cDNA preparations from the Detroit cells-internalized bacteria and that were cultured without Detroit cells, were labeled with either Alexafluor-555 or Alexafluor-647 depending on the experimental design ( i.e. dye swap experiment). Differentially labeled probes were then combined and purified. Using four independently isolated RNA preparations (biological replicates), a total of 8 experiments (incorporating 4 dye swaps) were performed. Accordingly eight hybridization measurements for this mutant were obtained. Exp-1 and -2 (GSM687276, GSM687310-dye swap) are the technical replicates of the biological sample-1, Exp-3 and -4 (GSM687311, GSM687312-dye swap) are technical replicates of biological sample-2, Exp-5 and -6, (GSM687313,GSM687319-dye swap,) are technical replicates of the biological sample-3, and finally Exp-7 and -8, (GSM687320,GSM687321-dye swap) are technical replicates of the biological sample-4. .

Project description:Single clones were isolated from the Detroit 562 cell line and implanted into NOD/SCID mice to determine whether clonal populations within one cell line had fuctionally distinct phenotypes, in the form of differing tumour initiating activity. From these data I found that different clonal populations had different tumour initiating activity, which lead to this investigation as to whether these functionally distinct populations were also genetically distinct.

Project description:We report changes in H3K27ac following LPS stimulation in Detroit 562 cells. We were able to identified LPS-increased H3K27ac regions which correlated with RELA binding as well as gene up-regulation. This data set is relevant for airborne bacterial sensing as Detroit 562 cells are nasopharyngeal epithelial cells and LPS is a gram negative bacterial endotoxin.
