hybridization is one the most commonly used techniques for developmental and evolutionary biology and has extensively contributed to the identification of distinct cell types and cell states, as well dissecting several molecular mechanisms involved in physiological processes. Moreover, it has been used as a tool to compare distinct gene expression patterns and, therefore, genetic programs across animal species. Nowadays, the predominance of transcriptomics in science has imposed the need to establish a reliable, fast and easy whole mount hybridization protocol. Here we describe a fluorescent hybridization protocol that is rapid, accurate and applicable in a great variety of marine species.

Soft tissue sarcomas are a heterogeneous group of malignancies arising from mesenchymal cells. Recent advancements in genomic profiling have identified novel gene fusions in these tumors, offering new insights into their pathogenesis and potential therapeutic targets. Here, we describe a spindle cell sarcoma harboring a novel gene fusion.

The spindle cell variant of papillary thyroid carcinoma (PTC) is exceptionally rare and poses significant diagnostic challenges due to its morphological overlap with other spindle cell lesions of the thyroid. We report a novel case of spindle cell variant PTC in a 66-year-old woman presenting with a TI-RADS 4 thyroid nodule, initially classified as Bethesda III on fine-needle aspiration. Histopathological examination revealed a biphasic tumor composed predominantly of bland spindle cells arranged in solid sheets and fascicles, admixed with entrapped thyroid follicles.

Local pH variations play a pivotal role in numerous critical biological processes. However, achieving the tunability and selectivity of pH detection remains a challenge. Here, we present a DNA-based strategy that enables programmable and selective pH responses, which is termed shadow-strand hybridization-actuated displacement engineering (SHADE).

Transmembrane signaling is essential for cellular communication, yet reconstituting such mechanisms in synthetic systems remains challenging. Here, we report a simple and robust DNA-based mechanism for transmembrane signaling in synthetic cells using cholesterol-modified single-stranded DNA (Chol-ssDNA). We discovered that anchored Chol-ssDNA spontaneously flips across the membrane of giant unilamellar lipid vesicles (GUVs) in a nucleation-driven, defect-mediated process.

Conjugated polymer nanoparticles (CPNs), especially poly(-phenylene ethynylene) nanoparticles (PPE-NPs), are promising candidates for bio-imaging due to their high photostability, adjustable optical characteristics, and biocompatibility. Despite their potential, the fluorescence mechanisms of these nanoparticles are not yet fully understood. In this work, we modeled a spherical PPE-NP in a water environment using 30 PPE dimer chains.
