Independent of the design of the life cycle of any insect, their growth and reproduction are highly choreographed through the action of two versatile hormones: ecdysteroids and juvenile hormones (JH). However, the means by which JH can target tissues and

Influenza A viruses enter host cells through endosomes, where acidification induces irreversible conformational changes of the viral hemagglutinin (HA) that drive the membrane fusion process. The prefusion conformation of the HA is metastable, and the pH of fusion can vary

Histamine (HA) is recognized by its target cells via four G-protein-coupled receptors, referred to as histamine H1-receptor (H1R), H2R, H3R, and H4R. Both H1R and H4R exert pro-inflammatory functions. However, their signal transduction pathways have never been analyzed in a

Transient receptor potential ankyrin1 (TRPA1) and transient receptor potential vanilloid 1 (TRPV1) are members of the TRP superfamily of structurally related, nonselective cation channels and mediators of several signaling pathways. Previously, we identified methyl syringate as an hTRPA1 agonist with

Epidermal-dermal interaction plays important roles in physiological events such as wound healing. In this study, we examined a double paracrine mechanism between keratinocytes and fibroblasts through interleukin-1 (IL-1) and an IL-1-induced inflammatory mediator prostaglandin E₂ (PGE₂) using the skin equivalent.

We sought to identify miRNAs that can efficiently induce apoptosis in ovarian cancer cells by overcoming BCL-X(L) and MCL1 anti-apoptotic activity, using combined computational and experimental approaches. We found that miR-491-5p efficiently induces apoptosis in IGROV1-R10 cells by directly inhibiting

The P2X7 receptor (P2X7R) is a ligand-gated ion channel that conducts Na(+), K(+), and Ca(2+) when activated by extracellular ATP. In various cell types, such as secretory epithelia, the P2X7R is co-expressed with Ca(2+)-dependent Cl(-) channels of the TMEM16/anoctamin family.

Voltage-gated, CaV2.3 calcium channels and neurokinin-1 (NK1) receptors are both present in nuclei of the central nervous system. When transiently coexpressed in human embryonic kidney (HEK) 293 cells, CaV2.3 is primarily inhibited during strong, agonist-dependent activation of NK1 receptors. NK1

Echinacoside is a natural compound with potent reactive oxygen species (ROS)-scavenging and anti-oxidative bioactivities, which protect cells from oxidative damages. As cancer cells are often under intense oxidative stress, we therefore tested if Echinacoside treatment would promote cancer development. Surprisingly

The vascular endothelial growth factor (VEGF)-C-induced down-regulation of VEGF receptor (VEGFR)-3 is important in lymphangiogenesis. Here, we demonstrate that VEGF-C, -D, and -C156S, but not VEGF-A, down-regulate VEGFR-3. VEGF-C stimulates VEGFR-3 tyrosyl phosphorylation and transient phosphorylation of extracellular signal-regulated kinase
