Most patients with advanced melanomas have a known primary site [melanoma of known primary (MKP)]. However, 2%-9% of patients are diagnosed with melanoma metastasis of unknown primary (MUP). As MUP and MKP have similar UV-induced mutations and molecular signatures, it is proposed that the primary tumor has regressed completely in patients with MUP.

Article Synopsis
  • The Hierarchical Taxonomy of Psychopathology (HiTOP) groups mental disorders based on their symptoms and underlying patterns, including a focus on personality functioning (PF) as a significant factor in mental health.
  • This study explored how PF fits into the HiTOP framework and its ability to predict broader issues related to mental health, such as affective well-being (AWB) and psychosocial impairment (PSI), using data from a mental health app with over 27,000 users.
  • Findings suggest that PF plays a crucial role in explaining transdiagnostic variance in mental health conditions and can be useful for clinicians in assessing and treating a variety of disorders by focusing on key aspects of personality functioning.

Article Synopsis
  • - Niemann-Pick disease Type C (NPC) is a neurodegenerative disorder caused by mutations in the NPC1 gene, resulting in cholesterol buildup in cells, particularly affecting microglial function.
  • - In neonatal Npc1 mutant mice, researchers observed reactive microglia with increased CD68 and phagocytic activity, indicating disrupted TREM2-mTOR signaling pathways.
  • - The study found that deleting the Trem2 gene in Npc1-deficient BV2 cells partially restored microglial function, suggesting that NPC1 loss alters microglial morphology and lysosomal function via TREM2-mTOR signaling.

Article Synopsis
  • The study investigates the use of osmotic gradient ektacytometry (Osmoscan) as a potential diagnostic tool to differentiate neuroacanthocytosis syndromes (NAS) from other neurodegenerative diseases.
  • Significant differences in red blood cell properties were found in NAS patients compared to healthy controls and patients with other conditions, particularly in specific osmolality measurements.
  • While some Osmoscan parameters showed promise, only two of them achieved 100% specificity for distinguishing NAS from other diseases, highlighting the need for further research with larger samples to solidify diagnostic criteria.

Combined inhibition of EZH2 and CDK4/6 perturbs endoplasmic reticulum-mitochondrial homeostasis and increases antitumor activity against glioblastoma.

NPJ Precis Oncol

July 2024

Department of Medicine, Clinic III -Hematology, Oncology, Palliative Medicine, Rostock University Medical Center, University of Rostock, Rostock, Germany.

He, we show that combined use of the EZH2 inhibitor GSK126 and the CDK4/6 inhibitor abemaciclib synergistically enhances antitumoral effects in preclinical GBM models. Dual blockade led to HIF1α upregulation and CalR translocation, accompanied by massive impairment of mitochondrial function. Basal oxygen consumption rate, ATP synthesis, and maximal mitochondrial respiration decreased, confirming disrupted endoplasmic reticulum-mitochondrial homeostasis.

Patterns of morphological evolution in the raptorial appendages of praying mantises.

Insect Sci

July 2024

Department of Cytology and Evolutionary Biology, Zoological Institute and Museum, University of Greifswald, Greifswald, Germany.

Mantodea (praying mantises) is a group of exclusively predatory insects, which, together with nonraptorial blattodeans (cockroaches and termites) and groups exclusively found in the fossil record, form the group Dictyoptera. A central characteristic of Mantodea is the specialization of their first pair of legs as raptorial grasping appendages, but the evolution from walking to raptorial legs is not yet fully understood. Here, we trace the evolution of the raptorial appendages in Dictyoptera through time using a morphometric (morphospaces) approach.

The animal product most used as a stimulatory additive for cell cultivation is still fetal bovine serum (FBS). Besides the ethical concerns regarding serum collection, the main problems of FBS are batch-to-batch variability and the resulting risk of lower reproducibility, the differences between species, the presence of undefined/unknown components, and the risk of contamination. In contrast, pig blood, which is a by-product of slaughter, is a sufficiently available and sustainable resource with a high degree of standardization in terms of donor age, weight, and genetics.
