Natural disease course and genotype-phenotype correlations in Complex I deficiency caused by nuclear gene defects: what we learned from 130 cases

open access: yesJournal of Inherited Metabolic Disease, 2012
Mitochondrial complex I is the largest multi-protein enzyme complex of the oxidative phosphorylation system. Seven subunits of this complex are encoded by the mitochondrial and the remainder by the nuclear genome. We review the natural disease course and

Decoding the dual role of autophagy in cancer through transcriptional and epigenetic regulation

open access: yesFEBS Letters, EarlyView.
Transcriptional and epigenetic regulation controls autophagy, which exerts context‐dependent effects on cancer: Autophagy suppresses tumorigenesis by maintaining cellular homeostasis or promotes tumor progression by supporting survival under stress. In this “In a Nutshell” article, we explore the intricate mechanisms of the dual function of autophagy ...

Recent advances in the functional explorations of nuclear microRNAs

open access: yesFrontiers in Immunology, 2023
Approximately 22 nucleotide-long non-coding small RNAs (ncRNAs) play crucial roles in physiological and pathological activities, including microRNAs (miRNAs).

Coordination of plastid and nuclear gene expression [PDF]

open access: yesPhilosophical Transactions of the Royal Society of London. Series B: Biological Sciences, 2003
The coordinated expression of genes distributed between the nuclear and plastid genomes is essential for the assembly of functional chloroplasts. Although the nucleus has a pre–eminent role in controlling chloroplast biogenesis, there is considerable evidence that the expression of nuclear genes encoding photosynthesis–related proteins is ...

Environmental control of plant nuclear gene expression by chloroplast redox signals

open access: yesFrontiers in Plant Science, 2012
Plant photosynthesis takes place in specialized cell organelles, the chloroplasts, which perform all essential steps of this process. The proteins involved in photosynthesis are encoded by genes located on the plastid and nuclear genomes. Proper function

Autophagy in cancer and protein conformational disorders

open access: yesFEBS Letters, EarlyView.
Autophagy plays a crucial role in numerous biological processes, including protein and organelle quality control, development, immunity, and metabolism. Hence, dysregulation or mutations in autophagy‐related genes have been implicated in a wide range of human diseases.

A novel zinc finger transcriptional repressor, ZNF224, interacts with the negative regulatory element (AldA-NRE) and inhibits gene expression [PDF]

open access: yes, 2003
The interaction between the negative cis-element (AldA-NRE) and p97 repressor nuclear protein is a key step in modulating transcription of the human and mouse aldolase A (AldA) gene during the cell cycle and differentiation.

CTCF regulates positioning of the human cystic fibrosis gene in association with a histone deacetylase

open access: yesGenomics Data, 2014
The nuclear positioning of mammalian genes often correlates with their functional state. For instance, the human cystic fibrosis transmembrane conductance regulator (CFTR) gene associates with the nuclear periphery in its inactive state, but occupies ...

The Nuclear Lamina as a Gene-silencing Hub [PDF]

open access: yesCurrent Issues in Molecular Biology, 2012
There is accumulating evidence that the nuclear periphery is a transcriptionally repressive compartment. A surprisingly large fraction of the genome is either in transient or permanent contact with nuclear envelope, where the majority of genes are maintained in a silent state, waiting to be awakened during cell differentiation.
