p28 and nrc peptides are two anticancer peptides with various mechanisms have shown to be effective against breast cancer. therefore, it seems that construction of a chimeric protein containing the two peptides might cause synergistic cytotoxic effects. however, since the two peptides bear opposite charges, production of a chimeric protein in which the two moieties do not intervene each other i...

: The venoms of Tunisian wildlife snakes are complex mixtures containing proteins/ peptides and non-protein molecules. Proteins the most abundant compounds responsible for biological effects venoms. Snake proteins have enzymatic or nonenzymatic activities, which grouped into different families, including C-type lectin proteins, disintegrins (long, medium short disintegrins), Kunitz-type serine ...

Purpose. The objective of this study was to compare the salivary protein profiles from individuals diagnosed with breast cancer that were either HER2/neu receptor positive or negative. Methods. Two pooled saliva specimens underwent proteomic analysis. One pooled specimen was from women diagnosed with stage IIa HER2/neu-receptor-positive breast cancer patients (n = 10) and the other was from wom...

insects and ticks. Perhaps for this reason a variety of salivary anti-hemostatic compounds are found in this diverse group of arthropods. Many different salivary anti-clotting and antiplatelet agents and vasodilators have been described. Salivary vasodilators range from inorganic nitric oxide to prostaglandins, various different peptides and enzymes that destroy norepinephrine. Several anti-clo...

Crystallographic data analyses indicate that  three types of prolinium cations, along with two types of hydrogen  bonding,  produce and stabilize the helical structure of  triprolinium 12-phosphomolybdate. There are similarities between this organic-inorganic compound and peptides/proteins. The stronger “conventional” hydrogen bonds and the less common C-H…O attractions play critical roles in g...

Chemotherapy continues to be the standard treatment for advanced or metastasized cancer. However, commonly used chemotherapeutic agents may induce damage in healthy cells and tissues. Thus, in recent years, there has been an increased focus on the development of new, efficient anticancer drugs exhibiting low toxicity and that are not affected by mechanisms of chemoresistance. In the present wor...
