Article Abstract

Changes in lifestyle in developed countries have triggered the prevalence of obesity and type 2 diabetes mellitus (T2DM) in the latest years. Consequently, these metabolic diseases associated to insulin resistance, and the morbidity associated with them, accounts for enormous costs for the health systems. The best way to face this problem is to identify potential therapeutic targets and/or early biomarkers to help in the treatment and in the early detection. In the insulin receptor signaling cascade, the activities of protein tyrosine kinases and phosphatases are coordinated, thus, protein tyrosine kinases amplify the insulin signaling response, whereas phosphatases are required for the regulation of the rate and duration of that response. The focus of this review is to summarize the impact of transmembrane receptor protein tyrosine phosphatase (RPTPs) in the insulin signaling cascade and secretion, and their implication in metabolic diseases such as obesity and T2DM.

Anti-cancer effect of midazolam via downregulating YWHAH in papillary thyroid cancer cells.

Discov Oncol

January 2025

Department of Anesthesiology, The First Affiliated Hospital, Zhejiang University School of Medicine, No.1367 Wenyi West Road, Yuhang District, Hangzhou, 311100, People's Republic of China.

The work is aimed to investigate whether midazolam functions in thyroid cancer and reveal the potential mechanism of action. Cell viability was detected by CCK-8 method when treated by varying doses of midazolam to detect the cytotoxicity of midazolam on human thyroid follicular epithelial cell line and thyroid cancer cell lines. In thyroid cancer cells, EDU staining, wound healing and transwell assays were respectively used to detect cell proliferation, migration and invasion.

Chordoma is a rare malignant tumor with a higher incidence in males than in females. There is an increasing number of clinical studies related to tyrosine kinase inhibitors (TKIs), yet the efficacy and safety of different drugs vary. In this single-arm meta-analysis evaluating the efficacy and safety of TKIs for chordoma treatment, 12 studies involving 365 patients were analyzed.

Self-sufficient biocatalytic cascade for the continuous synthesis of danshensu in flow.

Appl Microbiol Biotechnol

January 2025

Department of Chemistry, Biochemistry and Pharmaceutical Sciences, University of Bern, Freiestrasse 3, 3012, Bern, Switzerland.

A new strategy has been developed to successfully produce the active component danshensu ex vivo. For this purpose, phenylalanine dehydrogenase from Bacillus sphaericus was combined with the novel hydroxyphenylpyruvate reductase from Mentha x piperita, thereby providing an in situ cofactor regeneration throughout the conversion process. The purified enzymes were co-immobilized and subsequently employed in batch biotransformation, resulting in 60% conversion of 10 mM L-dopa within 24 h, with a catalytic amount of NAD as cofactor.

Epidermal melanocytes form synaptic-like contacts with cutaneous nerve fibers, but the functional outcome of these connections remains elusive. In this pilot study we used our fully humanized re-innervated skin organ culture model to investigate melanocyte-nerve fiber interactions in UV-B-induced melanogenesis. UV-B-irradiation significantly enhanced melanin content and tyrosinase activity in re-innervated skin compared to non-innervated controls, indicating that neuronal presence is essential for exacerbating pigmentation upon UV-B irradiation in long-term culture.

Key Laboratory of Advanced Drug Preparation Technologies, Ministry of Education, School of Pharmaceutical Sciences, Zhengzhou University, Zhengzhou, Henan, China.

Targeted protein degradation (TPD) has emerged as a significant therapeutic approach for a variety of diseases, including cancer. Advances in TPD techniques, such as molecular glue (MG) and lysosome-dependent strategies, have shown substantial progress since the inception of the first PROTAC in 2001. The PROTAC methodology represents the forefront of TPD technology, with ongoing evaluation in more than 20 clinical trials for the treatment of diverse medical conditions.
