Type: miRNAs
Let-7 is a family of microRNAs (miRNAs) that play a crucial role in regulating gene expression.
Let-7 miRNAs are known to target genes involved in cell proliferation, differentiation, and survival, and have been shown to act as tumor suppressors.

In cancer, let-7 miRNAs are often downregulated, leading to the upregulation of their target genes, which can contribute to cancer development and progression.
