MetabolomicsMitochondrial glutamine import sustains mitochondrial translation independent of glutaminolysis in cancer_GlnFlux_untargeted metabolites

Oxidative phosphorylation (OXPHOS) fulfills energy metabolism and biosynthesis through tricarboxylic acid (TCA) cycle and an intact electron transport chain (ETC). Mitochondrial glutamine import (MGI) replenishes TCA cycle through glutaminolysis, but its broader roles in cancer remains unclear. H...

TranscriptomicstRNA Over-Expression in Breast Cancer
Increased proliferation and elevated levels of protein synthesis are characteristic of transformed and tumor cells. Though components of the translation machinery are often misregulated in cancers, how tRNA plays a role in cancer cells has not been explored. We compare genome-wide tRNA expression in...

TranscriptomicsThe human mitochondrial transcriptome
The human mitochondrial genome comprises a distinct genetic system transcribed as precursor polycistronic transcripts that are subsequently cleaved to generate individual mRNAs, tRNAs and rRNAs. Here we provide a comprehensive analysis of the human mitochondrial transcriptome across multiple cell li...

MetabolomicsArginine starvation kills tumor cells through aspartate exhaustion and mitochondrial dysfunction
Defective arginine synthesis, due to the silencing of argininosuccinate synthase 1 (ASS1), is a common metabolic vulnerability in cancer, known as arginine auxotrophy. Understanding how arginine depletion kills arginine-auxotrophic cancer cells will facilitate the development of anti-cancer therapeu...

GenomicsGenome-wide distribution of RNA-DNA hybrids identifies RNase H targets in tRNA genes, retrotransposons and mitochondria
During transcription the nascent RNA can invade the DNA template, forming extended RNA-DNA duplexes (R-loops). Here we employ ChIP-seq in strains expressing or lacking RNase H to map targets of RNase H activity throughout budding yeast genome. In wild-type strains, R-loops were readily detected over...

TranscriptomicsRetrotransposon Ty1 integration targets specifically positioned asymmetric nucleosomal DNA segments in tRNA hotspots
Using a TIP-seq protocol (specifically isolating transposon insertion junctions) we determined that the Ty1 retrotransposon targets tRNA genes and, in particular, we determined that the transposon inserts into nucleosomal DNA in an asymmetric pattern. TIP-seq recovery of transposon insertion junctio...

ProteomicsFragmentation of mitochondrial mt-tRNA-LeuTAA provides a regulator of metabolic physiology
In this study, we discovered cytosolic and mitochondrial fragments resulting from tRNA and mt-tRNA cleavage, which may act as new regulators of cellular and metabolic functions. We selected the mt-tRF-LeuTAA fragment derived from a tRNA encoded by the mitochondrial genome for further investigation, ...
