Purpose: The purpose of this study was to detect the distribution of different lectin receptors in primary cancer cells as well as in the case of metastasis, as these biomolecules can potentially predict cancer development in certain tissues and systems.

Methods: To detect lectin receptors in tumors, the authors used conjugates of lectins purified by affinity chromatography with peroxidase, and studied their localization in paraffin sections of 12 cases of primary cancer and 33 of its metastases.

Result: In primary cancers and their metastases, there is a distinct mosaicity in the histotopography of individual lectins, especially peanut and soybean lectin.

Target class-focused drug discovery has a strong track record in pharmaceutical research, yet public domain data indicate that many members of protein families remain unliganded. Here we present a systematic approach to scale up the discovery and characterization of small molecule ligands for the WD40 repeat (WDR) protein family. We developed a comprehensive suite of protocols for protein production, crystallography, and biophysical, biochemical, and cellular assays.

Hydrogen-deuterium eXchange mass spectrometry (HDX-MS) is increasingly used in drug development to locate binding sites and to identify allosteric effects in drug/target interactions. However, the potential of this technique to quantitatively analyze drug candidate libraries remains largely unexplored. Here, a collection of 13 WDR5-targeting small molecules with surface plasmon resonance (SPR) dissociation coefficients () ranging from 20 nM to ∼116 μM were characterized using differential HDX-MS (ΔHDX-MS).

Background: This article presents a case study of two white male siblings of 24 and 31 years of age of self-reported Ukrainian ethnicity diagnosed with adrenomyeloneuropathy (AMN) associated with a novel splice site mutation in the ABCD1 gene. AMN represents a form of X-linked adrenoleukodystrophy (X-ALD) characterized by demyelination of the spinal cord and peripheral nerves. The case also presents the first adult haematopoietic stem cell transplant (HSCT) for adrenomyeloneuropathy in Ukraine.
