The transcription factor c-Myc amplifies the transcription of many growth-related genes in cancer cells, but its role as an oncogene is not fully understood.

Substitutions in general translation initiation factor eIF1A found as recurring somatic mutations in uveal melanoma destabilize the closed conformation of the preinitiation complex at the start codon and increase discrimination against suboptimal initiation codons genome-wide.

Quantitative FRET UPR induction assay is used to measure IRE1 and BIP association and dissociation by a variety of ER misfolded proteins and by an important BiP substrate-binding domain mutant, significantly enhancing the evidence for the allosteric UPR induction model.

Cryo-EM reveals atomic details of two membrane half-channels for translocation of protons that drive rotary catalysis in ATP synthase.

A new post-translational regulatory mechanism of K-Ras is identified, which expands the function of reversible protein lysine fatty acylation and offers new possibility to target the K-Ras oncoprotein.

The survival and growth of solid tumor cells in hypoxia is dependent on fatty acid storage in triglyceride lipid droplets promoted by HIG2.

Competing DNA polymerases at the DNA sliding clamp are revealed by single-molecule co-localization studies.

Individual cells display heterogeneous fluctuations in metabolic activity, with amplitude and kinetics controlled by interlocking feedbacks between glycolysis and the Insulin/PI3K/Akt signaling pathway.

Live-cell nanometer-resolution RNA labeling method enables transcriptome-wide mapping of endogenous RNAs in nuclear, cytosol, ER, and mitochondrial subcompartments.

The diffusion coefficients of proteins in the cytoplasm depend on their net charge and the distribution of charge over the protein surface, with positive proteins moving up to 100-fold slower because they bind to ribosomes.
