A breadth of preclinical studies now support the rationale of pluripotent stem cell-derived cell replacement therapies to alleviate motor symptoms in Parkinsonian patients. Replacement of the primary dysfunctional cell population in the disease, i.e.

Article Synopsis
  • Hutchinson-Gilford progeria syndrome (HGPS) is a rare genetic disorder caused by a mutation in the LMNA gene, leading to accelerated aging and severe cardiovascular issues starting within the first year of life.
  • The study found that progerin expression in vascular smooth muscle cells (VSMCs) causes increased cell death, which is linked to elevated levels of poly(ADP-Ribosyl)ation and reduced nicotinamide adenine dinucleotide (NAD) levels.
  • A new compound, trifluridine, was discovered to increase NAD levels by reducing PARP-1 activity, and its treatment showed potential in reducing VSMCs loss and improving clinical signs of progeria in mice

The cochaperone BCL2-associated athanogene 3 (BAG3), in complex with the heat shock protein HSPB8, facilitates mitotic rounding, spindle orientation, and proper abscission of daughter cells. BAG3 and HSPB8 mitotic functions implicate the sequestosome p62/SQSTM1, suggesting a role for protein quality control. However, the interplay between this chaperone-assisted pathway and the mitotic machinery is not known.

What if the next generation of successful treatments was hidden in the current pharmacopoeia? Identifying new indications for existing drugs, also called the drug repurposing or drug rediscovery process, is a highly efficient and low-cost strategy. First reported almost a century ago, drug repurposing has emerged as a valuable therapeutic option for diseases that do not have specific treatments and rare diseases, in particular. This review focuses on Hutchinson-Gilford progeria syndrome (HGPS), a rare genetic disorder that induces accelerated and precocious aging, for which drug repurposing has led to the discovery of several potential treatments over the past decade.

Nonpuerperal uterine inversion is a very rare event. We reported on the first ever case of nonpuerperal uterine inversion due to adenomyosis. Magnetic resonance imaging is recommended in cases with an unusual vaginal mass, so that this possible uterine etiology can be taken into consideration.
