Example Sentences

"We already knew that certain mutations in these subunits are linked to the eye disease retinitis pigmentosa," says Dr. Cristian Prieto-Garcia from the Institute of Biochemistry II, the first author of the study.

From Science Daily

"We suspect it may also explain why retinal cells in retinitis pigmentosa patients die. Defective splicing variants might also play a role in the development of neurodegenerative diseases like Alzheimer's or Parkinson's. On the other hand, this mechanism may be targeted by new therapeutic approaches for types of cancer that are highly dependent on the correct function of the spliceosome."
