They suggest including anti-MCV (mutated citrullinated vimentin), anti-RA33 (heterogeneous nuclear ribonucleoprotein A2) and ACPA, the rationale being that the identification of a range of autoantibodies may improve prediction of outcome, as well as responses to chemotherapy/immunotherapy as these agents may have selective effects on autoantibody production.
RNAs in cells are associated with RBPs to form ribonucleoprotein (RNP) complexes.
It is an experimental fact, at any rate, that every cell contains a system of RNAs and ribonucleoproteins that makes proteins according to the rules of a code, and that system can be described therefore as a 'code-and-template-dependent-protein-maker', i.
Some are particular to lupus (eg, anti-Sm, anti-ribosomal P, anti-double stranded DNA), while others are also found in other rheumatologic conditions (eg, antinuclear antibodies [ANA], anti-single stranded DNA, rheumatoid factor, anti-phospholipid, anti- Ro (SS-A), anti-La (SS-B), and anti-nuclear ribonucleoprotein (anti-nRNP).
The mothers of children with neonatal lupus likely have anti-Ro, anti-La, or anti-U1 ribonucleoprotein antibodies, he noted, and the condition can be associated with congenital heart block.
1986 consider that the destine of the chromatoid body and annular lamellae is the spermatids neck region, which also contains ribonucleoprotein (Esponda, 1983; Czaker, 1985), suggesting that the chromatoid body and annular lamellae may be involved with the transport of these proteins to structures of the spermatids neck region.
Antifibrillarin/anti-U3 ribonucleoprotein (anti-U3 RNP) antibodies are seen in 10%, and anti-neutrophilic cytoplasmic antibodies (ANCA) are seen in about 4%, though mostly in patients with diffuse systemic sclerosis.
Finally, around the time patients become symptomatic, antinuclear ribonucleoprotein antibodies appear in blood.
Immuno-localization of NS3 protein in RHBV-infected rice tissues: Polyclonal NS3 antibodies were purified and the IgG fraction was labeled with colloidal gold (20 nm and 10 nm gold particles); healthy and RHBV-infected rice leaves were analyzed in combination with mouse anti-viral ribonucleoprotein (Nprotein) antibodies labeled with 5 nm colloidal gold.
Studies have shown that 85-95% of cancer cells over-express a ribonucleoprotein called telomerase.
