Old paragraph: As red blood cells contain no nucleus, protein biosynthesis is currently assumed to be absent in these cells. Because of the lack of nuclei and organelles, mature red blood cells do not contain DNA and cannot synthesize RNA, and consequently cannot divide and have limited repair capabilities.

Request for new edit: Recent research contradicts the prior belief that mature human red blood cells lack DNA and RNA due to nucleus loss during differentiation. Instead, it reveals the presence of various microRNAs and mRNA transcripts in these cells. Analysis of erythrocyte microRNAs found a subgroup of HbSS with severe anemia, linked to elevated miR-144 expression and NRF2 repression. Furthermore, recent evidence suggests substantial amounts of large RNA species, including mRNA and non-coding RNA, exist in mature red blood cells. Kimmy3737 (talk) 21:03, 17 November 2023 (UTC)

Would like to add new information to the following sentence:

"As red blood cells contain no nucleus, protein biosynthesis is currently assumed to be absent in these cells"

New research from Kumar et. al has identified low levels of protein translation in red blood cells, specifically with regard to alpha and beta globin translation. Further, the researchers have also indicated the presence of polysomes through transmission electron microscopy. I think it could be informative to future readers to be familiar with this information as the current page indicates that RBCs are not capable of protein synthesis, which stands in contradiction to their long lifespans that seem to be unsustainable without protein synthesis. I have drafted a suggested change below:

"Because red blood cells contain no nucleus, protein biosynthesis was previously assumed to be absent in these cells; however, recent studies have revealed low levels of α-globin and β-globin mRNA transcript translation in addition to the presence of polysomes in red blood cells, providing evidence that supports their long life span" (Kumar et. al 2022).

Suggestion to change the title to "erythrocytes"

The scientific name for these cells is erythrocytes. They are known as red blood cells, not the other way around. Misplaced Pages is a scientific source, not a children's coloring book. Lajoswinkler (talk) 19:25, 16 January 2024 (UTC)

Misplaced Pages is an encyclopedia for the general reader - scientific info is detailed on pages - entry terms preferably use the generally known terms.--Iztwoz (talk) 11:44, 10 March 2024 (UTC)

That's why we have redirects. Misplaced Pages is not supposed to promote general ignorance, but keep at it. Lajoswinkler (talk) 19:46, 11 March 2024 (UTC)

I thought it might be nice to add the actual Greek to the etymology, e.g.

From Ancient Greek ἐρυθρός (erythrós, “red”), and from Neo-Latin cyta, from Ancient Greek κύτος (kútos, “vessel, jar”). — Preceding unsigned comment added by 185.152.1.145 (talk) 13:41, 10 August 2024 (UTC)
