Pheno-RNA, a method to identify genes linked to a specific phenotype: application to cellular transformation

Project description:Cellular transformation is associated with dramatic changes in gene expression, but it is difficult to determine which regulated genes are oncogenically relevant. Here, we describe Pheno-RNA, a general approach to identify candidate genes associated with a specific phenotype. Specifically, we generate a “phenotypic series” by treating a non-transformed breast cell line with a wide variety of molecules that induce cellular transformation to various extents. By performing transcriptional profiling across this phenotypic series, the expression profile of every gene can be correlated with the transformed phenotype. We identify ~200 genes whose expression profiles are very highly correlated with the transformation phenotype, strongly suggesting their importance in transformation. Within biological categories linked to cancer, some genes show high correlations with the transformed phenotype, but others do not. Many genes whose expression profiles are highly correlated with transformation have never been linked to cancer, suggesting the involvement of heretofore unknown genes in cancer .

Mechanism of TP53 and RB1 inactivation-induced neuroendocrine phenotype transformation in TKI-resistant lung adenocarcinoma

Project description:In order to study the mechanism of co-inactivation of RB1 and TP53 in the transformation of lung adenocarcinoma to small cell lung cancer, we established the NCI-H1975 cell line with RB1 knockdown.NCI-H1975 cells were cultured and infected with lentivirus expressing RB1-shRNA (n=3) or pLKO.1-shRNA (n=3), We then performed transcriptome sequencing (RNA-seq) on the above cells.

Agrobacterium-mediated cassava transformation for the Asian-elite variety KU50

Project description:Agrobacterium-mediated cassava transformation via friable embryogenic callus (FEC) has allowed the robust production of transgenic cassava. So far, the transformation has been performed mostly for 60444 (the model cassava variety for transformation) and African varieties due to the high ability of callus induction and good regeneration capacity from embryogenic tissues. It is important to develop the transformation methods for elite cassava varieties in Asian area which is one of main cassava production area in the world, however, the suitable transformation method for Asian elite variety via FEC has not been reported. Here, we developed the transformation method in Kasetsart 50 (KU50) which has the highest planting area in Thailand and Vietnam. In cassava transformation, the preparation of FEC is considered as a key step. The ability of FEC induction from KU50 was improved efficiently by the use of media with reduced nutrients and excess vitamin B1, even if the FEC-inducible efficiency was 5 times lower compared with cv. 60444. The optimal concentration of NAA for regeneration from FEC to cotyledon was 1.0 mg/L and the optimal concentration of BAP for shoot formation from cotyledon was 0.4 mg/L. The transformation efficiency was estimated as 45% for 60444 and 22% for KU50. Transcriptome analysis indicated that KU50 FEC is out of balance between cell wall production and assembly, because the expression of the genes related to loosing cell wall was upregulated in the FEC from KU50 compared with 60444. We hope that the developed technology will contribute to molecular breeding of useful cassava plants in Asia by the simultaneous use of genome-editing technology.

S100A8/S100A9 cytokine functions as transcriptional coactivator during breast cellular transformation

Project description:In an inducible model of human breast cellular transformation, we map genome-wide chromatin binding of S100A8, S100A9 and Pol II. We show that the calcium-dependent cytokines S100A8 and S100A9 are recruited to numerous promoters and enhancers. This recruitment is associated with multiple DNA sequence motifs recognized by DNA-binding transcription factors that are linked to transcriptional activation and are important for transformation. Nuclear-specific expression of S100A8/A9 promotes oncogenic transcription and leads to enhanced breast transformation phenotype. These results suggest that, in addition to its classical cytokine function, S100A8/A9 can act as a transcriptional co-activator.
