Article Synopsis
- Podocyte dysfunction and loss significantly contribute to proteinuria and FSGS, a common cause of this condition, yet the mechanisms behind podocyte injury and protection are not well understood.
- The study found that podocytes can create tunneling nanotubes (TNTs) dependent on the protein M-Sec, which is involved in cell communication and protection against injury.
- Results showed that M-Sec is overexpressed in FSGS, and its deletion led to podocyte damage and mitochondrial issues; restoring M-Sec improved podocyte function, suggesting it could be a potential therapeutic target for FSGS.
Background: A current, albeit unproven, hypothesis is that an acceleration of cellular senescence is involved in impaired renal repair and progression of glomerular diseases. Focal segmental glomerulosclerosis (FSGS) is a glomerular disease with a substantial risk for progression to ESRD. However, if and to what extent cell senescence predicts a negative outcome in FSGS is still unknown.

In addition to classical progression factors, other atherosclerosis-related factors, including hyperuricemia (HU), have been associated to the renal progression of IgAN. Increased serum uric acid (SUA) levels are well known to be concomitant of cardiovascular and kidney diseases, and have been proposed to be implicated in the development of arteriolar damage (AD).

In this study we observed upregulation of MSTN mRNA (~8 to 10-fold increase) both in the glomeruli and tubulointerstitium in diabetic nephropathy (DN). In DN, immunoreactive MSTN was mainly localized in the tubuli and interstitium (∼4-8 fold increase), where it colocalized in CD45 cells.

With the aim of better understanding the relationship between BP behavior and progression, we looked at time-averaged SBP and time-averaged proteinuria and renal outcome in a single-center cohort of IgAN patients.
Methods: Among 248 consecutive patients referred to the Clinic of Nephrology of San Martino Hospital from 1996 to 2018 for native renal biopsy with a diagnosis of IgAN, we retrospectively analyzed 145 with available data at baseline and during follow-up.
