We previously showed that a fungal protein, p15, induces neurite outgrowth and differentiation of rat pheochromocytoma PC12 cells. We report here the identification and characterization of a protein similar to p15, found in Streptomyces coelicolor A3(2). This hypothetical protein, tentatively named Scp15, has significant similarity with p15, including conserved positions of four cysteine residues involved in the formation of essential disulfide bonds in p15. Hexahistidine-tagged recombinant Scp15 proteins were produced in Escherichia coli, purified, and analyzed for their neurite-inducing activity. Although they were less active than p15, they dose-dependently induced neurites and the expression of neurofilament M. Neurite outgrowth by Scp15 was inhibited by nicardipine, suggesting that Scp15 induces neurites via activation of a calcium signaling pathway.

Background: Pancreatic cancer is a highly aggressive neoplasm characterized by poor diagnosis. Amino acids play a prominent role in the occurrence and progression of pancreatic cancer as essential building blocks for protein synthesis and key regulators of cellular metabolism. Understanding the interplay between pancreatic cancer and amino acid metabolism offers potential avenues for improving patient clinical outcomes.

Background: During the latter stages of their development, mammalian oocytes under dramatic chromatin reconfiguration, transitioning from a non-surrounded nucleolus (NSN) to a surrounded nucleolus (SN) stage, and concomitant transcriptional silencing. Although the NSN-SN transition is known to be essential for developmental competence of the oocyte, less is known about the accompanying molecular changes. Here we examine the changes in the transcriptome and DNA methylation during the NSN to SN transition in mouse oocytes.

Background: In-person interaction offers invaluable benefits to people. To guarantee safe in-person activities during a COVID-19 outbreak, effective identification of infectious individuals is essential. In this study, we aim to analyze the impact of screening with antigen tests in schools and workplaces on identifying COVID-19 infections.

The PSH-Assessment Measure (PSH-AM) consists of a Clinical Features Scale and a diagnosis likelihood tool (DLT) intended to quantify the severity of sympathetically mediated symptoms and the likelihood that they are due to PSH, respectively, on a daily basis. Here, we aim to identify and explore the value of dynamic trends in the evolution of sympathetic hyperactivity following acute TBI using elements of the PSH-AM.
