HDAC9 Gene Linked to Heart Disease and Diabetes
Last
month, cardiac researchers at the University of Cincinnati discovered a
unique gene associated with heart disease and diabetes. This gene, the
HDAC9, was shown to prevent the effects of obesity (e.g. high blood
sugar, cholesterol, and fatty liver disease) when deleted from mice
being fed high fat diets.
The HDAC9 gene codes for the enzyme Histone Deacetylase 9, which
belongs to a class of enzymes responsible for controlling DNA
expression. Removing this enzyme from the cellular atmosphere affects
the gene expression profile of the cell in a way that, according to Dr.
Chatterjee, “prevent[s] mice from developing obesity-related diseases
during chronic high-fat feeding.”
Typically, an increase in caloric intake is supposed to decrease the
expression of HDAC9 gene, which is supposed to prime fat cells for
efficient storage of fat content. However, chronic over-feeding leads to
an increase in the expression of HDAC9 in fat cells, leading to a host
of obesity-related symptoms and diseases (such as high blood sugar, high
blood pressure, fatty liver disease, and heart disease).
With the above knowledge, however, scientists can now look to create
drugs that target and decrease the expression of HDAC9, so that like the
mice in Dr. Chatterjee’s study, obesity-related symptoms and diseases
can be mitigated in humans who may be suffering from such conditions.

Nos dias de hoje, onde os hábitos sócio-culturais dos países desenvolvidos tornam a sua população cada vez mais predisposta a doenças cardiovasculares e diabetes, é necessário cada vez mais alternativas no diagnóstico, monitorização e tratamento dessas mesmas doenças.
ResponderEliminarCom a descoberta deste gene HDAC9, associado a essas patologias de cariz fatal, é dado mais um passo importante na prevenção e tratamento, permitindo melhores condições de vida a indivíduos que apresentam o problema.
