Project description:eIF3 is the largest translation initiation factor in mammalian cells, consisting of 13 subunits. This translation initiation factor is involved in multiple processes of protein translation in cells, including translation initiation, termination, and ribosome recycling. Several studies have reported that multiple subunits of eIF3 exhibit abnormal expression in tumor cells and play an important role in the occurrence and development of tumors. In this study, it was found that changes in the expression level of EIF3G significantly affected the growth of non-small cell lung cancer. Knockdown of EIF3G inhibited the intracellular protein translation process of non-small cell lung cancer cells H1299. Through the study of translatome, it was found that knockdown of EIF3G significantly affected the cell cycle processes in H1299 cells. In vitro cell experiments also showed that changes in the expression level of EIF3G influences the cell cycle distribution of H1299 cells. This study is the first to explore the impact of knockdown of EIF3G on the translatome of H1299 cells.
Project description:we find METTL3 associates with polyribosomes and promotes translation. METTL3 depletion inhibits translation, and both wild-type and catalytically inactive METTL3 promote translation when tethered to the 3' untranslated region (UTR) of a reporter mRNA. Mechanistically, METTL3 enhances mRNA translation through an interaction with the translation initiation machinery. m6A seq in A549 and H1299 cells, RNA seq in METTL3 knockdown cells
Project description:Knockdown LRRK1-CAPT in NCI-H1299 lung cancer cell line by two independent siRNAs, to investigate the mechanism of LRRK1-CAPT in regulation of cell proliferation.
Project description:We used the NanoString Human nCounter miRNA expression platform to compare the miRNA expression profiles of QKI-5 knockdown H1299 cells and control cells We found that QKI-5 knockdown significantly changed miRNA expression pattern in lung cancer cells
Project description:CCT3 was knocked down in H1299 and A549 cell lines. TMT-MS was employed to detect the differences of intracellular proteins abundance.
Project description:We performed translatome and transcriptome sequencing of A549, H1299 and HBE cells and analyzed the translation ratio (TR) of all genes
Project description:We performed translatome and transcriptome sequencing of A549, H1299 and HBE cells and analyzed the translation ratio (TR) of all genes Total RNA and ribosome-bound RNA were extracted from A549, H1299 and HBE cells, and the polyA+ mRNA was sequenced using Illumina GAIIx and HiSeq-2000. The reads were mapped to RefSeq RNA reference sequences and the expression level were quantified by rpkM calculation.
Project description:This is a transcription profiling study on yeast undergoing glucose depletion. It reveals that glucose depletion inhibits translation initiation in a mechanism involving eIF4A loss and 48S pre-initiation complex accumulation, while the pentose phosphate pathway is co-ordinately up-regulated
Project description:This is a polysome/monosome profiling study on yeast undergoing glucose depletion. Polysomes and monosomes are extracted and the transcripts bound to each fraction are measured by microarray. The study reveals that glucose depletion inhibits translation initiation in a mechanism involving eIF4A loss and 48S pre-initiation complex accumulation, while the pentose phosphate pathway is co-ordinately up-regulated
