Isolation of signal transduction complexes using biotin and crosslinking methodologies. | LitMetric

AI Article Synopsis

Article Abstract

We have developed a strategy to preferentially label the N-terminal alpha-amino groups of intact proteins allowing the internal epsilon-amino groups to remain free to react with chemical crosslinking reagents. The convergence of these methodologies allows biotinylated ligands to bind to their receptors within the cell membrane followed by removal of the crosslinked complex from cell lysate. This technique allows for the isolation of protein complexes in an MS-compatible system, thus providing a tool for furthering our understanding of signal transduction.

The role of MAPK pathway in gastric cancer: unveiling molecular crosstalk and therapeutic prospects.

J Transl Med

December 2024

Department of General Surgery, The Lu'an Affiliated Hospital of Anhui Medical University, Lu'an People's Hospital, Lu'an, 237000, China.

Gastric cancer remains a significant health burden globally, especially prevalent in Asian and European regions. Despite a notable decline in incidence in the United States and Western Europe over recent decades, the disease's persistence underscores the urgency for advanced research in its pathogenesis and treatment strategies. Central to this pursuit is the exploration of the mitogen-activated protein kinase (MAPK) pathway, a pivotal cellular mechanism implicated in the complex processes of gastric cancer development, including cellular proliferation, invasion, migration, and metastasis.

Mechanical ventilation (MV) remains a cornerstone of critical care; however, its prolonged application can exacerbate lung injury, leading to ventilator-induced lung injury (VILI). Although previous studies have implicated ferroptosis in the pathogenesis of VILI, the underlying mechanisms remain unclear. This study investigated the roles of ferritinophagy in ferroptosis subsequent to VILI.

Background: Previous research on the lower gastrointestinal tract has proved that microbial dysbiosis can lead to intestinal barrier dysfunction and enhanced visceral sensitivity, thus triggering bowel symptoms. Whether esophageal microbial dysbiosis also contributes to the development of gastroesophageal reflux (GER) symptoms, which are known to be associated with impaired esophageal barrier integrity, remains to be explored.

Methods: Patients with GER symptoms (gastroesophageal reflux disease [GERD] and functional esophageal disorders [FED]), duodenal ulcer patients and healthy controls were prospectively included for esophageal microbial analysis.

Doublecortin regulates the mitochondrial-dependent apoptosis in glioma via Rho-A/Net-1/p38-MAPK signaling.

Mol Med

December 2024

Department of Neurobiology and Anatomy, Key Laboratory of Neurobiology, Xuzhou Medical University, 209, Tongshan Road, Xuzhou, 221004, China.

Doublecortin (DCX) is a microtubule-associated protein known to be a key regulator of neuronal migration and differentiation during brain development. However, the role of DCX, particularly in regulating the survival and growth of glioma cells, remains unclear. In this study, we utilized CRISPR/Cas9 technology to knock down DCX in the human glioma cell line (U251).

mFusion: a multiscale fusion method bridging neuroimages to genes through neurotransmissions in mental health disorders.

Commun Biol

December 2024

National Clinical Research Center for Aging and Medicine at Huashan Hospital, Institute of Science and Technology for Brain-Inspired Intelligence, Research Institute of Intelligent Complex Systems, Fudan University, Shanghai, China.

Mental health disorders emerge from complex interactions among neurobiological processes across multiple scales, which poses challenges in uncovering pathological pathways from molecular dysfunction to neuroimaging changes. Here, we proposed a multiscale fusion (mFusion) method to evaluate the relevance of each gene to the neuroimaging traits of mental health disorders. We combined gene-neuroimaging associations with gene-positron emission tomography (PET) and PET-neuroimaging associations using protein-protein interaction networks, where various genes traced by PET maps are involved in neurotransmission.
