Researchers have created a comprehensive map of the DNA sequences that control gene expression in human cells, identifying 2.37 million potential regulatory elements. This registry reveals previously unrecognized classes of elements and illuminates how noncoding genetic variation contributes to cell type-specific traits.
Researchers reprogrammed the epigenetic code to affect tumour growth and survival in multiple myeloma. This study presents a comprehensive map of epigenetic alterations in multiple myeloma, highlighting site-specific increases in DNA and protein methylation that control gene activity.
Researchers successfully modulate the activity of key immune system genes using CRISPR-Cas9 technology, revealing a new approach to treating inflammatory diseases. The study demonstrates precise control over gene expression and its impact on tumour growth and inflammation.
Researchers found that maternal iron deficiency can lead to male-to-female sex reversal in mouse embryos due to impaired Sry gene activation. Iron is necessary for KDM3A's enzymatic activity, which removes histone methylation allowing the Sry gene to become active.
As women age, more genes on their X chromosomes escape silencing, potentially influencing disease. This epigenetic change may explain sex-based differences in age-related diseases.
Exposure to multiple environmental stressors simultaneously impairs the ability of herring larvae to react at a molecular level, reducing their capacity for acclimatization. This can lead to increased protein damage and cell injury, potentially affecting growth and survival.
A recent study by Nara Institute of Science and Technology reveals a new mechanism for dynamic gene silencing and reactivation, highlighting the intricate roles of proteins like SDG7. The research team identified a competitive interaction between SDGs and PRC2 at PREs, allowing for efficient gene activation through H3K36 methylation.
A CHARMed collaboration has created a set of molecular tools called CHARMs that can turn off disease-causing genes, including those coding for the prion protein. The tools have shown promise in silencing the prion protein gene and improving or eliminating disease symptoms in animals.
Researchers at Kobe University discovered a new gene, FDFT1, responsible for porokeratosis by identifying epigenetic silencing. Patients with localized lesions didn't have inherited damaged copies, leading to a hypothesis that epigenetic changes are the first hit. The findings have implications for treatment and counseling.
A team of researchers at the University of Johannesburg has made a groundbreaking discovery about how tomato plants defend themselves against the devastating ToCSV virus. By studying the molecular genetics of infected tomato varieties, they found that viral DNA methylation plays a crucial role in resistance to ToCSV.
Researchers have identified the Xist gene as a critical regulator of fetal development in mice, leading to miscarriage and abnormal placentas when epigenetic instructions are missing. The study's findings suggest that failed Xist imprinting can be 'cured' by targeting specific genes involved in histone modifications.
Researchers have uncovered a collaboration between RNA decay and chromatin regulating complexes that work together to control the levels of transposable element RNAs, preventing genetic instability. The study reveals an unprecedented mechanism of transcriptional and post-transcriptional regulation.
Researchers at McGill University have discovered that plants can forget epigenetic silencing, a process crucial for breeding enhanced crops. This 'molecular amnesia' varies depending on genome position, offering new avenues for understanding gene regulation and developing cancer treatments.
