The quick emerging of the several targeted therapies and the concept of personnalized medicine underlie the necessity to develop and to well organize a molecular biology (or molecular pathology) unit of high quality, dedicated to clinical care, in order to look for tissular and cellular theragnosis biomarkers. This new and sudden area of activity for a clinical pathologist is strongly linked to the knowledge of a new medical speciality in health care institutions. Thus, the molecular pathology (or molecular biology made from cellular or tissular samples) can nicely be implemented in a clinical pathology laboratory. This new mission for a pathologist has to be done in respect with a great quality assurance which should allow obtaining in a short-term an ISO 15189 accreditation to keep going to perform this activity. The present work aims to describe the main steps to be set up in the order to get an ISO 15189 accreditation in molecular pathology. The different chapters of this norm will not be described in their exhaustivity, but in their large lines. Finally, we will describe the potential difficulties and pitfalls to be avoided before getting this accreditation.

Background: Central nervous system tumors (CNSTs) represent a significant oncological challenge in pediatric populations, particularly in developing regions where access to diagnostic and therapeutic resources is limited.
Methods: This research investigates the epidemiology, histological classifications, and survival outcomes of CNST in a cohort of pediatric patients aged 0 to 19 years within a 25-year retrospective study at the Civil Hospital of Guadalajara, Mexico, from 1999 to 2024.
Results: Data was analyzed from 273 patients who met inclusion criteria, revealing a higher incidence in males (51.

Clear cell renal cell carcinoma (ccRCC) is a highly malignant tumor characterized by a significant propensity for recurrence and metastasis. DNA methylation has emerged as a critical epigenetic mechanism with substantial utility in cancer diagnosis. In this study, multi-omics data were utilized to investigate the target genes regulated by the transcription factor MYC-associated zinc finger protein (MAZ) in ccRCC, leading to the identification of thymidine phosphorylase (TYMP) as a gene with notably elevated expression in ccRCC.

Background: Chronic inflammation is well recognized as a key factor related to renal function deterioration in patients with diabetic kidney disease (DKD). Neutrophil extracellular traps (NETs) play an important role in amplifying inflammation. With respect to NET-related genes, the aim of this study was to explore the mechanism of DKD progression and therefore identify potential intervention targets.

The expansion of single-cell analytical techniques has empowered the exploration of diverse biological questions at the individual cells. Droplet-based single-cell RNA sequencing (scRNA-seq) methods have been particularly widely used due to their high-throughput capabilities and small reaction volumes. While commercial systems have contributed to the widespread adoption of droplet-based scRNA-seq, their relatively high cost limits the ability to profile large numbers of cells and samples.
