The classical myeloproliferative neoplasms (MPN) are comparatively uncommon in children and display a degree of mutational naivety if considering the high frequency of known MPN driver events observed in the corresponding adult diseases. Whole exome sequencing has unravelled much of the underlying molecular complexity of MPN in adult patients yet less is known of the pathogenetic mechanisms when these diseases occur in childhood. It is proposed that such methodological approaches will contribute significant insights into the molecular landscape of childhood MPN that may in turn impact on understanding the pathophysiology of disease in their adult counterparts.

Spatial transcriptomics technologies have been extensively applied in biological research, enabling the study of transcriptome while preserving the spatial context of tissues. Paired with spatial transcriptomics data, platforms often provide histology and (or) chromatin images, which capture cellular morphology and chromatin organization. Additionally, single-cell RNA sequencing (scRNA-seq) data from matching tissues often accompany spatial data, offering a transcriptome-wide gene expression profile of individual cells.

These innovative drugs target multiple cellular or molecular pathways simultaneously, offering a more comprehensive anticancer approach and addressing some of the limitations inherent in traditional monotherapies. However, preclinical assessment of multispecific drugs remains challenging, as conventional tumor models often lack the necessary complexity to accurately reflect the interactions between various cell types and targets.

The advancement of disease-modifying treatments (DMTs) for Alzheimer's disease (AD), along with the approval of three amyloid-targeting therapies in the US and several other countries, represents a significant development in the treatment landscape, offering new hope for addressing this once untreatable chronic progressive disease. However, significant challenges persist that could impede the successful integration of this class of drugs into clinical practice. These challenges include determining patient eligibility, appropriate use of diagnostic tools and genetic testing in patient care pathways, effective detection and monitoring of side effects, and improving the healthcare system's readiness by engaging both primary care and dementia specialists.

Background: The efficacy of immune checkpoint inhibitors (ICIs) depends on the tumor immune microenvironment (TIME), with a preference for a T cell-inflamed TIME. However, challenges in tissue-based assessments via biopsies have triggered the exploration of non-invasive alternatives, such as radiomics, to comprehensively evaluate TIME across diverse cancers. To address these challenges, we develop an ICI response signature by integrating radiomics with T cell-inflamed gene-expression profiles.

Survival of brachyuran crabs is temperature-dependent and thermal stress promotes changes during molting. We aimed to decipher the impact of thermal stresses on the X-organ/sinus gland (XO/SG) complex, a temperature-sensitive neuroendocrine tissue involved in the molting regulation of Callinectes sapidus during the intermolt and premolt phases. We employed a proteogenomic approach using specimens subjected to control (24 °C), cold (19 °C), and heat (29 °C) temperatures.
