A study by the University of Texas M. D. Anderson Cancer Center found that women with high levels of Dicer and Drosha proteins had a median survival of 11 years, while those with low levels had only 2.66 years. Low levels of Dicer are also predictive of poor outcomes in lung and breast cancer patients.

The primary cilium is a vital cellular sensor that detects signals to guide cells toward wounds, promoting efficient healing. Defective cilia impede wound closure and lead to uncontrolled cell migration, potentially contributing to invasive cancers and fibrosis.
Research suggests that autism and schizophrenia may stem from similar physical abnormalities caused by disruptions in early organogenesis, typically between 20-40 days after fertilization. This developmental stage is critical in shaping the body's development, and errors during this period can lead to various mental health disorders.
