The Claim
Normalizing total RNA to muscle wet weight in biopsy samples systematically underestimates ribosomal expansion during hypertrophy due to sarcoplasmic dilution, resulting in false-negative conclusions in the human literature regarding the role of ribosome biogenesis in muscle growth.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When scientists measure RNA in muscle tissue samples and adjust for muscle weight, they may miss increases in ribosomes because the fluid content of muscle cells expands during growth, making ribosome levels appear lower than they are.

Normalizing total RNA to muscle wet weight in biopsy samples systematically underestimates ribosomal expansion during hypertrophy due to sarcoplasmic dilution, leading to false-negative conclusions in the human literature about the role of ribosome biogenesis in muscle growth.
When muscle fibers grow, they fill with fluid and other non-ribosomal material, making each gram of muscle contain less RNA even though the total number of ribosomes increases. This makes it look like ribosome production is not increasing, when in fact it is expanding dramatically to support muscle growth.
What the research says
1 studyWhen muscles grow, they fill up with fluid and other stuff, so if you measure RNA per gram of muscle, it looks like less RNA is being made—even though the muscle is actually making way more ribosomes. This study says that’s a mistake in how scientists have been measuring things.
