Small RNA linked to death in younger people with COVID-19

In patients under 55, higher levels of a gene-regulating RNA were associated with death, with a reported odds ratio of 6.00.In patients under 55, higher levels of a gene-regulating RNA were associated with death, with a reported odds ratio of 6.00.

Preprint: study of younger people with COVID-19Mechanisms

Limit: Absolute death risks are not reported, limiting interpretation of the relative odds

Progeria disrupts cells in the intestinal lining in mice

Mice carrying one copy of a progeria-linked mutation developed increased gut leakage from 30 weeks, reaching levels reported in naturally aged mice over 20 months old.Mice carrying one copy of a progeria-linked mutation developed increased gut leakage from 30 weeks, reaching levels reported in naturally aged mice over 20 months old.

Preprint: experiments in heterozygous progeria miceLMNA

Limit: The link between mitochondrial dysfunction and impaired cell maturation remains a proposed model
