The Claim
miR-143 expression in visceral adipose tissue is not significantly associated with β-cell function (HOMA-B) in non-diabetic adults after adjusting for BMI, age, and sex, and its association with insulin resistance is primarily mediated through insulin sensitivity rather than insulin secretion.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In non-diabetic adults, the level of miR-143 in visceral fat does not correlate with how well pancreatic beta cells secrete insulin, and its link to insulin resistance is mainly through how responsive tissues are to insulin, not through insulin production.

High levels of miR-143 in belly fat block the cells' ability to respond to insulin, making the body less able to take up sugar from the blood. This causes insulin resistance, but the pancreas still releases the same amount of insulin as before.
What the research says
1 studyThe study found that higher levels of miR-143 in belly fat are linked to lower insulin production by the pancreas, which means it does affect how much insulin the body makes — not just how well the body uses insulin. This goes against the claim that it doesn’t affect insulin production.
