Liver fibrosis or scarring is the most common pathological feature caused by chronic liver injury, and is widely considered one of the primary causes of morbidity and mortality. Circular rnas may bind rnabinding proteins or even base pair with rnas, resulting in the formation of large rnaprotein complexes.

These socalled noncoding rnas vary in length, but like proteincoding rnas, appear to be linear molecules with 5. Expression of canril is correlated with risk for atherosclerosis, a disease in which the arteries become hard. Among the most interesting classes of noncoding rnas are the recently described circular rnas several groups have reported the existence of circular rna circrnas molecules generated by a process called backsplicing wherein downstream exons are spliced to upstream exons in reverse order wilusz and sharp, 20. It is primarily characterised by hepatic stellate cells hsc.
