In a recent investigation, scientists from the AHB Lab found novel peptides with anti-cancer potential. According to a study published in Nature Communications, it was shown that cyclic peptides particularly link to chains of ubiquitin proteins, which are widely utilised as a \u201cdeath tag\u201d for damaged proteins. The proteasome then breaks down the damaged proteins after marking them.<\/p>\n
Before now, Technion researchers created a strategy for altering the ubiquitin processes. They chose to try a direct intervention in the ubiquitin chain rather than affecting the activity of enzymes that influence these pathways.<\/p>\n
In an earlier study, the researchers used this method to generate cyclic peptides that bind the K48-linked ubiquitin chains and prevent them from initiating the breakdown of the damaged proteins. Cells gradually die according to plan as a result of this disruption. The same study demonstrated how such an occurrence in a malignant tumour destroys cancer cells, potentially defending the patient.<\/p>\n

A peptide is an amino acid (AA) chain less than 50 amino acids long and you can stabilize by disulfide bonds. Although they have adequate biochemical and therapeutic differences, they are sufficiently different from small molecules and macromolecules in size. By using logical approaches, they can create peptides that precisely bind to and control protein interactions of interest, such as those involving oncogenic proteins. The three main processes that produce peptides are as follows:<\/p>\n
(a) Natural or bioactive peptides,<\/p>\n
(b) Genetic or recombinant libraries used to synthesize modified peptides,<\/p>\n
(c) Peptides produced from chemical libraries.<\/p>\n
Low-molecular-weight peptides can enter tumour tissues with a fair amount of affinity. Chemical synthesis might be used to create an affordable cancer treatment.<\/p>\n
