Can Fat Cells be Dangerous?

Fat cells, called adipocytes or adipose tissue primarily function to store fat. The presence of adipose tissue mostly seen under skin and inside the abdomen. The fat inside the abdomen is termed as visceral fat. These fat cells now draw the attention of researchers, regarding their role in diabetes II and cancer. Fat is used as fuel the body and is an essential part of any cell structure.
Now, it has been seen that fat helps cancer cells to grow faster. An enzyme called monoacylglycerol lipase (MAGL) that breaks down fat to fatty acids, found in abundance in the breast cancers, adipose tissue is a major constituent. Blocking the enzyme, in mouse models fed on normal diet slows growth of cancer cells.
Adipose tissue play a major role in diabetes II. The cells increasingly deliver inflammatory molecules to liver under influence of certain genes and resistance to insulin develop; so even in abidance of insulin in the body glucose metabolism is hampered.
Reduction in obesity helps in curtailing the risk of diabetes II and certain cancers.
