«We have investigated how the genome
of white
adipocytes is reprogrammed during
browning using advanced genome sequencing technologies.
Recently,
browning of white
adipocytes * 7 has been shown, where the resultant «beige
adipocytes» possesses similar characteristics
of brown adipocytes.
Beige cells have recently attracted a lot
of attention, especially because adults have very low numbers
of active
brown adipocytes that burn energy.
But around the neck and shoulders, there is a second form
of fat made
of brown adipocytes.
Brown fat
adipocytes use fat and glucose as sources
of energy.
Simultaneously, Lsd1 promotes the expression
of genes containing information for
brown adipocytes.
The researchers selectively ablated Lsd1 and inactivated its catalytic activity in
brown adipocytes, which triggered a profound whitening
of brown adipose tissue: The colour
of the
brown fat cells became paler, their size increased and they started to store energy instead
of expending it.
In his study, Wang found that pups born to mother mice fed a triple dose
of Vitamin A were born with more fat - burning
brown fat cells, and had more small blood vessels in their adipose tissues, providing precursor cells for energy - burning beige
adipocytes
Complete loss
of mitochondrial CLPP protease protects mice from diet ‐ induced obesity and insulin ‐ resistance but impairs cold ‐ induced thermogenesis due to a decline in
brown adipocyte function.
They were crowded with mitochondria that were much smaller than those
of brown adipocytes.
These differences indicate SGBS cells may help to identify mechanisms leading to
browning, and inform our understanding for the use
of SGBS vis - à - vis primary human subcutaneous
adipocytes as a human white
adipocyte model, guiding the selection
of appropriate cell models in future metabolic research.
Uncoupling protein 1 (Ucp1) is the functional marker
of both
brown and beige
adipocytes.
The increase in mRNA levels
of many genes due to the consumption
of tea catechins may lead to improvements in fat metabolism and have a positive effect on BW via increased FO and
brown adipose tissue (BAT) development and a decrease in
adipocyte differentiation.
