Background: Breast cancer is the leading cause of cancer-related mortality in women. Deregulation of miRNAs is frequently observed in breast cancer and affects tumor biology. A pre-miRNA, such as pre-miR-1307, gives rise to several mature miRNA molecules with distinct functions.

Ductular reaction (DR) is the hallmark of cholestatic diseases manifested in the proliferation of bile ductules lined by biliary epithelial cells (BECs). It is commonly associated with an increased risk of fibrosis and liver failure. The receptor for advanced glycation end products (RAGE) was identified as a critical mediator of DR during chronic injury.

Quality control procedures play a pivotal role in ensuring the reliability and consistency of data generated in mass spectrometry-based proteomics laboratories. However, the lack of standardized quality control practices across laboratories poses challenges for data comparability and reproducibility. In response, we conducted a harmonization study within proteomics laboratories of the Core for Life alliance with the aim of establishing a common quality control framework, which facilitates comprehensive quality assessment and identification of potential sources of performance drift.

Article Synopsis
  • BK polyomavirus-associated nephropathy (BKPyVAN) is a significant complication after kidney transplantation, usually managed by reducing immunosuppression when BK polyomavirus (BKPyV) is detected.
  • A study involving 1,076 kidney transplant recipients found a higher risk of developing de novo donor-specific antibodies (dnDSA) in patients with high BKPyV DNA loads compared to those without, suggesting that the required immunosuppression reduction can worsen immune responses.
  • While high BKPyV DNAemia increased dnDSA risk, there was no significant difference in the occurrence of biopsy-proven acute rejection (BPAR) between groups, indicating a need for better strategies to manage BKPyV infections in transplant patients.
