The influence of aging on pathologic and immunobiologic parameters of invasive ductal breast carcinoma [PDF]
Background/Aim. Most human cancers, including breast one, increase in frequency with aging. The aim of this study was to explore the hypothesis that aging also alters breast cancer biology. Methods.

Isoquercitrin Alleviates Diabetic Nephropathy by Inhibiting STAT3 Phosphorylation and Dimerization
This study identified a natural compound, isoquercitrin, which significantly alleviated kidney inflammation and fibrosis by inhibiting STAT3 activity. Isoquercitrin forms a strong, noncovalent bond that directly binds to STAT3. Isoquercitrin binds to the pY+1 pocket of the SH2 domain of STAT3 via hydrogen bonding with Ser668, Gln635, and Gln633 ...

A Thermodynamic Model for Receptor Clustering [PDF]
Intracellular signaling often arises from ligand-induced oligomerization of cell surface receptors. This oligomerization or clustering process is fundamentally a cooperative behavior between near-neighbor receptor molecules; the properties of this cooperative process clearly affects the signal transduction.

High- and low-conductance NMDA receptors are present in layer 4 spiny stellate and layer 2/3 pyramidal neurons of mouse barrel cortex [PDF]
NMDA receptors are ion channels activated by the neurotransmitter glutamate in the mammalian brain and are important in synaptic function and plasticity, but are also found in extrasynaptic locations and influence neuronal excitability. There are different NMDA receptor subtypes which differ in their single-channel conductance.

Plac1+ Tumor Cell‐Treg Interplay Supports Tumorigenesis and Progression of Head and Neck Cancer
Meng et al. screen genes in the CTAs family and find Plac1 is specifically expressed in head and neck squamous cell carcinoma (HNSCC) cells. They reveal that Plac1 expression promotes HNSCC progression directly by activating PI3K/AKT signaling pathway.

Interaction of antibodies with ErbB receptor extracellular regions [PDF]
Antibodies to the extracellular region of the ErbB receptors have played key roles in the development of a mechanistic understanding of this family of receptor tyrosine kinases. An extensively studied class of such antibodies inhibits activation of ErbB receptors, and these antibodies have been the focus of intense development as anti-cancer agents. In

Cargo binding promotes KDEL receptor clustering at the mammalian cell surface [PDF]
Transmembrane receptor clustering is a ubiquitous phenomenon in pro- and eukaryotic cells to physically sense receptor/ligand interactions and subsequently translate an exogenous signal into a cellular response. Despite that receptor cluster formation has been described for a wide variety of receptors, ranging from chemotactic receptors in bacteria to ...

The present study employs small RNA sequencing to identify the types and content of microRNAs (miRNAs) in four widely utilized plant‐derived extracellular vesicles (pEVs). The functional annotation reveals that the pEV miRNAs are involved in regulating the progression of human cancer and viral infection, thereby demonstrating the crosskingdom ...

Mechanisms of light in regulating the chick pineal clock. Abstract The circadian clock significantly impacts animal health and productivity, with light playing a crucial role in regulating circadian rhythms. However, the mechanisms behind light‐induced circadian transmission remain unclear, particularly in light‐sensitive avian species.

Neuregulins (NRGs) and their cognate ErbB receptors (ErbB2–ErbB4) constitute a vast group of proteins encoded by six different genes (NRG1–6) and many isoforms with critical roles in the development and functioning of the nervous system.
