: 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 ...

Currently, the most widely used denture-base material, poly(methyl methacrylate), a polymer, does not efficiently bind natural antimicrobial cationic proteins secreted in saliva as part of the pellicle surface (a thin layer of salivary glycoproteins and immunoglobulins, including mucins, amylase, and secretory IgA, deposited on teeth and other oral cavity surfaces). These antimicrobial peptides...

In the pathogenesis of periodontitis, an infection-induced inflammatory disease of the tooth-supporting tissues, there is a complex interaction between the subgingival microbiota and host tissues. A periodontal diagnostic tool for detecting the initiation and progression of the disease, monitoring the response to therapy, or measuring the degree of susceptibility to future disease progression h...

The scavenger receptor cysteine-rich (SRCR) proteins form an archaic group of metazoan proteins characterized by the presence of SRCR domains. These proteins are classified in group A and B based on the number of conserved cysteine residues in their SRCR domains, i.e. six for group A and eight for group B. The protein DMBT1 (deleted in malignant brain tumors 1), which is identical to salivary a...

The fishing industry generates tons of waste great intrinsic value due to its high content biomolecules such as proteins. processing proteins can result in products with nutritional, pharmacological, and technological interest the peptides that be derived from them. This review work compiles investigations have performed on production fish origin using pepsin catalyst corresponding hydrolytic r...

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...

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...

The genetic predisposition to taste 6-n-propylthiouracil (PROP) varies among individuals and is associated with salivary levels of Ps-1 and II-2 peptides, belonging to the basic proline-rich protein family (bPRP). We evaluated the role of these proteins and free amino acids that selectively interact with the PROP molecule, in modulating bitter taste responsiveness. Subjects were classified by t...
