 Context examples 

IRES-dependent initiation of protein synthesis occurs during apoptosis or some viral infection (e.g., picornavirus).

(Internal Ribosome Entry Pathway, NCI Thesaurus/BIOCARTA)

A compound with activity against human picornaviruses.

(Disoxaril, NCI Thesaurus)

A (+) strand single strand RNA virus of the picornavirus family.

(Enterovirus, NCI Thesaurus)

IRESs are usually about 450 nucleotides in length and were first identified in picornavirus RNAs.

(Internal Ribosome Entry Site, NCI Thesaurus)

Internal ribosome entry sites (IRES) were first discovered in picornavirus RNAs but it is now clear that IRESs are also present in the 5' untranslated region of many eukaryotic genes including those encoding growth factors (e.g., VEGF, FGF2 and PDGF), genes whose protein products are associated with apoptosis (e.g., Apaf-1, IXAP), transcription factors (e.g., c- myc), and the potassium channel Kv1.4.
