TranscriptomicsExpression Profiling of Tissues versus Primary Cultures from Colorectal Cancer Patients
The main aim of this study is to evaluate how comparable the established colorectal primary tumor cultures are to the original tumor tissues obtained directly from patients in terms of their genomic profile for which they can be eventually utilized to improve in vitro drug assessment and facilitate ...

TranscriptomicsRegulation of hTERT by BCR-ABL at multiple levels in K562 cells
To investigate the mechanism of telomerase regulation in BCR-ABL positive cells due to its clinical value, we studied the catalytic component of telomerase, TERT. Our results suggest that BCR-ABL plays an important role in regulating hTERT in K562 (BCR-ABL positive human leukemia) cells. When Gleeve...

TranscriptomicsInvestigation of extra-telomeric effects of hTERT in neoplastic transformation of IMR90 cells
The complexity and heterogeneity of cancer cells are under-represented by the current experimental models which revolve around primary tumor cells, cancer cell lines, and rodent models. We used the transformed cell model in our studies. IMR90 and BJ fibroblast cells were transformed by three oncogen...

TranscriptomicsMutated RNA component of the telomerase induces apoptosis via GADD45-? in hTERT-overexpressing primary fibroblasts
Mutant template human telomerase RNAs (MT-hTers) have been shown to induce apoptosis in various cancerous cells that have high telomerase activity. However, the exact mechanisms by which MT-hTers inhibit the growth of cancer cells and affect normal somatic cells remain largely unknown. To determine ...

ProteomicsLabel-free proteomic analysis of apoptotic, necrotic and necroptotic DAMPs from HNSCC cells
Necroptosis is a newly discovered form of programmed cell death (PCD) showing necrotic features, including membrane permeabilization and the release of damage-associated molecular patterns (DAMPs). Studies have revealed both its tumorigenic role and therapeutic potential in various cancers, yet its ...

ProteomicsA chemical screen identifies PRMT5 as a therapeutic vulnerability for paclitaxel-resistant triple-negative breast cancer
Through chemical probe screening, we uncovered a novel mechanism of RNA splicing in paclitaxel-resistant TNBC and identified PRMTs as therapeutic targets.

ProteomicsThe identification of VAMP8 interactive protein under normal and EBSS condition
VAMP8 was first identified as an endosomal SNARE that participates in diverse biological functions, including autophagy fusion. We investigated the protein interaction and modification of VAMP8 upon starvation condition compared with normal condition, we thus excised the GFP-VAMP8 band from the Coo...
