What is new in hypertrophic cardiomyopathy?

Image
Hypertrophic cardiomyopathy is a complaint in which the heart muscle becomes thickened (hypertrophied). The thickened heart muscle can make it harder for the heart to pump blood. It frequently goes undiagnosed. Utmost people with the condition have no symptoms and experience no significant problems. For some, it can beget briefness of breath, casket pain or abnormal heart measures (arrhythmias). Treatment may include surgery, an implantable device or drug to decelerate or regulate the heart rate. Symptoms •                      Breathlessness with exertion or indeed at rest •                      Lump of the legs, ankles and bases •                      Bloating of the tummy due to fluid buildup •                      Cough while lying down HCM is autosomal dominant condition, meaning that individualities have a 50 chance of inheriting or passing on, the predilection to this complaint to their children. Hypertrophic cardiomyopathy is most frequently caused by abnormal gene

Do we have Maternal Effect Genes in Humans?

  Maternal genes are those genes whose products, RNA or protein, are produced or deposited in the oocyte or are present in the fertilized egg or embryo before expression of zygotic genes is initiated One well- characterized classic illustration of motherly effect is gravid diabetes. In humans, the first MEG was linked in 2006, in women who had endured a range of adverse reproductive issues, including hydatidiform intelligencers, robotic revocations, and bearings. Over 80 mammalian MEGs have latterly been linked, including several that have been associated with phenotypes in humans. Motherly effect genes (MEGs) render factors (e.g., RNA) that are present in the oocyte and needed for early embryonic development. Hence, while these genes and gene products are of motherly origin, their phenotypic consequences affect from goods on the embryo. Physical features similar as hair colour, hair texture, hairline, skin, and swollen modes are inherited from your mama. Genetically, you actually

What role does chromatin play in gene expression?

Image
Chromatin is a highly structured complex in which DNA is stored. Epigenetic processes regulate gene expression by altering the structure of chromatin. Actively transcribed genes are found in chromatin regions that are accessible, whereas transcriptionally silent genes are found in inaccessible chromatin regions. Whether it is a blessing or a curse, chromatin adds an extra layer of control over gene expression. This control is exercised via a slew of chemical modifications to histones and DNA known as epigenetic marks, which alter chromatin structure and provide specific recognition sites for regulatory factors. In response to environmental stimuli, the epigenome undergoes biochemical changes, which result in chromatin structure remodeling. The term "chromatin remodeling" primarily refers to the ATP-dependent process of genomic transformation by nucleosome-shifting enzymes such as the SWI/SNF complex. Epigenetics heavily relies on chromatin remodeling. Epigenetic modifi
