Epigenetic regulator MOF drives mitochondrial metabolism //www.koonmotors.com/releases/2023/10/231009191631.htm Researchers have unveiled a new mechanism for regulating mitochondrial function. The findings reveal the critical role played by the enzymatic activity of the lysine acetyltransferase MOF in maintaining mitochondrial integrity and function through acetylation of mitochondrial electron transport chain component COX17. Cells lacking MOF-mediated COX17 acetylation exhibit dramatic mitochondrial defects and impaired ability to produce energy. Underscoring the clinical relevance of these findings, the team also showed that cells from human patients with a developmental disorder caused by mutations in MOF also exhibited respiratory defects that could be ameliorated by interventions such as acetylation-mimetic COX17 or mitochondrially targeted MOF. Mon, 09 Oct 2023 19:16:31 EDT //www.koonmotors.com/releases/2023/10/231009191631.htm 研究了机制,注释的基因information passed from fathers to offspring //www.koonmotors.com/releases/2023/09/230906161820.htm Scientists have identified a key part of a mechanism that annotates genetic information before it is passed from fathers to their offspring. The findings shed new light on genomic imprinting, a fundamental, biological process in which a gene from one parent is switched off while the copy from the other parent remains active. Errors in imprinting are linked to a host of diseases, such as the rare disease Silver-Russell syndrome along with certain cancers and diabetes.

Tue, 28 Mar 2023 14:52:11 EDT //www.koonmotors.com/releases/2023/03/230328145211.htm Small differences in mom's behavior may show up in child's epigenome //www.koonmotors.com/releases/2023/03/230302073244.htm Adding evidence to the importance of early development, a new study links neutral maternal behavior toward infants with an epigenetic change in children related to stress response. Epigenetics are molecular processes independent of DNA that influence gene behavior. In this study, researchers found that neutral or awkward behavior of mothers with their babies at 12 months correlated with an epigenetic change called methylation, or the addition of methane and carbon molecules, on a gene called NR3C1 when the children were 7 years old. This gene has been associated with regulating the body's response to stress. Thu, 02 Mar 2023 07:32:44 EST //www.koonmotors.com/releases/2023/03/230302073244.htm New study unveils epigenetic 'traffic lights' controlling stop and go for gene activity //www.koonmotors.com/releases/2023/03/230301120825.htm A major new study reveals a 'traffic light' mechanism controlling genetic activity within cells -- a system which could potentially be targeted by cancer drugs already in development. The research describes how 'epigenetic' changes to the structure of DNA can act as a stop-go signal in determining whether a gene should be read. Unlike our genetic make-up, which is well understood, the world of epigenetics is still largely unexplored and referred to as the 'dark matter' of the genome. Wed, 01 Mar 2023 12:08:25 EST //www.koonmotors.com/releases/2023/03/230301120825.htm How sex differences influence lung injury in mice //www.koonmotors.com/releases/2023/01/230112113203.htm More than 2,500 genes exhibit significant sex differences in expression in mouse alveolar type II cells (AT2s), important for keeping the lungs functioning, potentially explaining sex biases in the prevalence and severity of lung diseases.

Thu, 22 Dec 2022 10:10:19 EST //www.koonmotors.com/releases/2022/12/221222101019.htm Twin study links exercise to beneficial epigenetic changes //www.koonmotors.com/releases/2022/12/221206083112.htm Consistent exercise can change not just waistlines but the very molecules in the human body that influence how genes behave, a new study of twins indicates. The study found that the more physically active siblings in identical twin pairs had lower signs of metabolic disease, measured by waist size and body mass index. This also correlated with differences in their epigenomes, the molecular processes that are around DNA and independent of DNA sequence, but influence gene expression. The more active twins had epigenetic marks linked to lowered metabolic syndrome, a condition that can lead to heart disease, stroke and type 2 diabetes. Since the identical twins have the same genetics, the study suggests that markers of metabolic disease are strongly influenced by how a person interacts with their environment as opposed to just their inherited genetics.
