Muscle-derived stem/progenitor cell dysfunction in Zmpste24-deficient progeroid mice limits muscle regeneration [PDF]
Introduction. Loss of adult stem cell function during aging contributes to impaired tissue regeneration. Here, we tested the aging-related decline in regeneration potential of adult stem cells residing in the skeletal muscle. Methods.

ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

Progeria in siblings: A rare case report
Progeria, also known as Hutchinson-Gilford syndrome, is an extremely rare, severe genetic condition wherein symptoms resembling aspects of aging are manifested at an early age. It is an autosomal dominant disorder.

Low and high expressing alleles of the LMNA gene: implications for laminopathy disease development. [PDF]
Today, there are at least a dozen different genetic disorders caused by mutations within the LMNA gene, and collectively, they are named laminopathies.

Proteostasis of organelles in aging and disease
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

Graphical Abstract This study explores whether a murine model of progeria has a delayed fracture healing phenotype that resembles chronological aging but with an accelerated timeline that could make it a valuable research tool. ABSTRACT An estimated 189 million bone fractures occurred in 2019 making it one of the most globally prevalent injuries ...

ABSTRACT CRISPR‐Cas9 systems revolutionized gene editing, but inherent drawbacks, namely DNA double‐strand breaks (DSBs) and the difficulty of achieving precise repairs (due to low HDR efficiency), led researchers to invent new, more accurate gene editing tools.

A 3-year-old girl with old face appearance: Case report
Hutchinson–Gilford Progeria Syndrome (HGPS) is a genetic disorder. Patients who suffer from this disorder show premature aging and a “plucked-bird” appearance on the face. This case reports a 3-year-old female, who manifested the symptoms of HGPS.

Mice with reduced expression of the telomere-associated protein Ft1 develop p53-sensitive progeroid traits [PDF]
Human AKTIP and mouse Ft1 are orthologous ubiquitin E2 variant proteins involved in telomere maintenance and DNA replication. AKTIP also interacts with A- and B-type lamins.

Hematopoietic (stem) cells—The elixir of life?
The aging of HSCs (hematopoietic stem cells) and the blood system leads to the decline of other organs. Rejuvenating aged HSCs improves the function of the blood system, slowing the aging of the heart, kidney, brain, and liver, and the occurrence of age‐related diseases.
