The present study successfully developed a method based on dual-functional probe for detecting breast cancer cells MCF-7 by recognizing the MUC1 protein cell surface. This integrated inductively coupled plasma mass spectrometry (ICP-MS) and fluorescence imaging technology, enhancing sensitivity, specificity, accuracy of detection. Additionally, through two-sample Mendelian randomization (MR) analysis, we verified potential correlation between (PIVW<0.05), while also proving no liver...

Calcitonin gene-related peptide (CGRP), the predominant neurotransmitter in capsaicin-sensitive sensory nerves, is a potent vasodilator and inhibits proliferation of vascular smooth muscle cells. Previous investigations have demonstrated that hypotensive effect rutaecarpine (Rut) associated to stimulation CGRP synthesis release via activation vanilloid receptor subtype 1 (VR1) phenol-induced hypertensive rat. This study tested whether depressor inhibiting hypertrophy Rut mediated by...
