LINE-1 (long interspersed element 1) is the only currently known active autonomous transposon in humans, and its retrotransposition may cause deleterious effects on the structure and function of host cell genomes and result in sporadic genetic diseases. Host cells therefore developed defence strategies to restrict LINE-1 mobilization. In this study, we demonstrated that IFN-inducible Schlafen5 (SLFN5) potently inhibits LINE-1 retrotransposition.

Background: The clinicopathologic profile of gastric cancer (GC) harboring oncogenic NTRK alterations are still unknown. And as reported, NTRK fusion was enriched in dMMR-type colorectal cancer (CRC), whereas in gastric cancer there was no research to explore the relationship between NTRK alterations and the expression of DNA mismatch repair proteins.

Melanin-concentrating hormone (MCH) is an orexigenic neuropeptide that acts through its receptor (MCHR1) to promote positive energy balance by increasing food intake and decreasing energy expenditure. MCH has been shown to inhibit dopamine release from the mesocorticolimbic dopamine pathway originating in the ventral tegmental area (VTA), and a hyperdopaminergic state underlies hyperactivity observed in animals lacking MCH or MCHR1. However, it is not known if the inhibitory effect of MCH on dopaminergic tone could be due to direct regulation of dopaminergic VTA neurons.

Background and Objectives: Acetylsalicylic acid (ASA) is widely used for preventing cerebrovascular and cardiovascular diseases. Gastrointestinal (GI) tract injury is one of the major complications of aspirin use, potentially leading to severe GI bleeding. However, no drugs for preventing aspirin-induced small intestinal injury have been developed. The aim of this study was to establish a human experimental model for investigating aspirin-induced small intestinal mucosal injury.

Antibodies have been commonly used to study protein phosphorylation since the first phospho-specific antibody was described in 1981. Antibodies can be developed so that they specifically recognize phosphorylated areas of particular proteins. In situ hybridization (ISH) is the technique where specific RNA or DNA molecules can be detected in a single cell without the need for antibodies.

Detection of phosphorylated proteins in tissue sections using immunohistochemistry (IHC) is a challenging task. The absence of tissue staining may be caused by either a lack of protein expression or a lack of protein activation via its phosphorylation. To address this problem, we employed Integrated Co-detection Workflow (ICW) protocol to analyze lung cancer tissue sections by combining in situ hybridization (ISH) with IHC.

Cells take in, consume, and synthesize nutrients for numerous physiological functions. This includes not only energy production but also macromolecule biosynthesis, which will further influence cellular signaling, redox homeostasis, and cell fate commitment. Therefore, alteration in cellular nutrient metabolism is associated with pathological conditions. Intervertebral discs, particularly the nucleus pulposus (NP), are avascular and exhibit unique metabolic preferences.
