This involves a protein called MAFA, which regulates expression of the insulin gene.

这涉及一种名为 MAFA 的蛋白质，它可以调节胰岛素基因的表达。

Suppressed levels of MAFA are a symptom of type-1 diabetes, so boosting its presence seemed a promising approach.

MAFA 水平受到抑制是 1 型糖尿病的症状，因此提高其存在似乎是一种有前途的方法。

So far, the researchers have shown that raising MAFA levels in beta cells derived from stem cells seems to increase the amount of insulin produced.

到目前为止，研究人员已经证明，提高源自干细胞的β细胞中的 MAFA 水平似乎会增加胰岛素的产生量。
