Wiring of vascular and neural networks requires precise guidance of growing blood vessels and axons, respectively, to reach their targets during development. Both of the processes share common molecular signaling pathways. Transient receptor potential canonical (TRPC) channels are calcium-permeable cation channels and gated via receptor- or store-operated mechanisms. Recent studies have revealed the requirement of TRPC channels in mediating guidance cue-induced calcium influx and their essential roles in regulating axon navigation and angiogenesis. Dissecting TRPC functions in these physiological processes may provide therapeutic implications for suppressing pathological angiogenesis and improving nerve regeneration.

Background: The protective function of the tetrandrine (TET)-mediated transient receptor potential vanilloid 2 (TRPV2) channel in myocardial ischemia/reperfusion injury (MI/RI) has been established in numerous investigations. The objective of the current study was to explain how TRPV2 further modulates downstream factors to influence the progression of MI/RI.
Methods: To this end, an MI/RI model in rats and a hypoxia-reoxygenation (H/R) cell model in H9c2 cells were constructed.

Many neurological and psychiatric diseases are characterized by pathological neuronal activity. Current treatments involve drugs, surgeries, and implantable devices to modulate or remove the affected region. However, none of these methods can be simultaneously nonsurgical and possess site- and cell type specificity.

Translocon-associated protein subunit beta (TRAPβ), also known as signal sequence receptor 2 (SSR2) serves as an auxiliary protein facilitating co-translational translocation in the endoplasmic reticulum (ER); however, its role in colorectal cancer is unknown to date. The objectives of the current study are to examine if TRAPβ/SSR2 knockdown affects the cell proliferation and to elucidate mechanisms by which TRAPβ/SSR2 regulates proliferation of human colorectal cancer. We silenced TRAPβ/SSR2 transiently and stably in human colorectal cancer cell lines and analyzed cell proliferative properties.

The thermosensitive transient receptor potential (Thermo-TRP) channel proteins comprise TRPA1, TRPV1-V4, and TRPM8. TRP channels are mainly situated on cellular surfaces and react to a range of external factors, including heat, cold, acidity, osmotic pressure, chemical signals, and flavors, as well as intracellular signals such as Ca, Na, and cytokines. The thermo-TRP channels are associated with many physiological signal pathways, with their distinct molecular structure making them promising drug targets for respiratory diseases.

While affinity purification-mass spectrometry (AP-MS) has significantly advanced protein-protein interaction (PPI) studies, its limitations in detecting weak, transient, and membrane-associated interactions remain. To address these challenges, we introduced a proteomic method termed affinity purification coupled proximity labeling-mass spectrometry (APPLE-MS), which combines the high specificity of Twin-Strep tag enrichment with PafA-mediated proximity labeling. This method achieves improved sensitivity while maintaining high specificity (4.
