Proof of Concept Study: Comparison of Semi-Automated RNA Isolation Methods from Archived Formalin-Fixed, Paraffin-Embedded Tissues with Clinical Routine RNA Isolation Methods.

High-quality RNA is crucial in clinical diagnostics and precision medicine. Formalin-fixed and paraffin-embedded (FFPE) tissues pose a challenge due to nucleic acid fragmentation and crosslinking. In this pilot study, various commercially available techniques for extracting RNA from small FFPE samples were compared.

Neoadjuvant Pembrolizumab in Stage I-III Deficient Mismatch Repair Colon Cancer: A Clinical Trial.

Objective: This clinical trial investigated the safety and efficacy of single-cycle pembrolizumab in patients with localized deficient mismatch repair (dMMR) colon cancer.

Background: Neoadjuvant immunotherapy has induced remarkable rates of pathological complete response in patients with dMMR colon cancer. However, the optimal length and type of treatment are yet to be determined.

How sensitive are protein hydration shells to electrolyte concentration and protein composition?

Proteins of obligate halophilic organisms have an unusually high number of acidic amino acids, thought to enable them to function in multimolar KCl environments. Clarifying the molecular scale mechanisms by which this occurs is relevant for biotechnology, to enable enzymatic synthesis of economically important small molecules in salty environments and other environments with low water activity. Previous studies have suggested that acidic amino acids are necessary at high salt concentration to keep the proteins hydrated by competing with the ions in solution for available water (the "solvent-only" model).

Rapid downregulation of DICER is a hallmark of adipose tissue upon high-fat diet feeding.

Adipose tissue regulates whole-body energy balance and is crucial for metabolic health. With energy surplus, adipose tissue expands, which may lead to local areas of hypoxia and inflammation, and consequently impair whole-body insulin sensitivity. We report that DICER, a key enzyme for miRNA maturation, is significantly lower in abdominal subcutaneous white adipose tissue of men with obesity compared with men with a lean phenotype.
