The present invention includes methods and compositions for increasing longevity of a cell and increasing cellular resistance to stress. In certain embodiments, the invention includes a method to induce gene expression of a homolog of Pachytene Checkpoint 2 (pch-2) or bmk-1 gene. The present invention also includes methods to treat oxidative stress or induce cellular death or apoptosis by administering a composition comprising a modulator of pch-2 or bmk-1 homolog gene expression.

This document relates to materials and methods for controlling ligand gated ion channel (LGIC) activity. For example, modified LGICs including at least one LGIC subunit having a modified ligand binding domain (LBD) and/or a modified ion pore domain (IPD) are provided. Also provided are exogenous LGIC ligands that can bind to and activate the modified LGIC, as well as methods of modulating ion transport across the membrane of a cell of a mammal, methods of modulating the excitability of a cell in a mammal, and methods of treating a mammal having a channelopathy.

A process for producing an arginine-rich peptide mixture and the application thereof in cervical cancer therapy is provided. The process includes the following steps: A suspension of walnut meal and egg albumin is pretreated with ultrahigh pressure, and then digested by alkaline proteinase and papain in separated steps with the ultrasonic and microwave-assisted extraction. The peptides of interest are isolated from filtration supernatant obtained after the enzyme digestion by reversed phase high-performance liquid chromatography. By using the peptide mixture as a template, acrylic acid and methyl acrylic acid as functional monomers, triethylene glycol dimethacrylate as cross-linking agent, and isopropylthioxanthone in acetone as a photoinitiator, polymerization is induced by ultraviolet light to form a surface imprinted membrane for isolating and enriching the peptides of interest from the supernatant. The arginine content in the peptide mixture is more than 18%. The arginine-rich peptide mixture is able to strongly suppress the proliferation of human cervical cancer Hela cells. The approach is applicable to reduce the cost of production and speed up the commercialization of large-scale production.

Compositions and methods are described for a polymer hydrogel created by a cycloaddition reaction between an azide and an alkyne that proceeds rapidly without catalyst to produce the polymer hydrogel in less than ninety seconds. The polymer hydrogel can be used in in vivo applications for the localized delivery of therapeutic agent in aqueous solutions. An example of therapeutic delivery of a protein in a mouse model is demonstrated.
