Small regulatory bacterial RNAs regulating the envelope stress response
PublikacjaMost bacteria encode a large repertoire of RNA-based regulatory mechanisms. Recent discoveries have revealed that the expression of many genes is controlled by a plethora of base-pairing noncoding small regulatory RNAs (sRNAs), regulatory RNA-binding proteins and RNA-degrading enzymes. Some of these RNA-based regulated processes respond to stress conditions and are involved in the maintenance of cellular homeostasis. They achieve...

The influence of pre- and postharvest treatments on selected biological and epigenetic activities of Brassica sprouts
PublikacjaIntroduction The Brassica vegetables are rich in glucosinolates (GLs), which are enzymatically hydrolysed to bioactive isothiocynates (ITC) and indoles, regarded as the most promising chemopreventing agents. However, in the majority of brassica sprouts the GL conversion into these beneficial derivatives occurs at the level of about 1 %, while in cabbage leaves exceeds 70%. Since sprouts represent plant material, which is frequently...

Anticancer Properties of Amino Acid and Peptide Derivatives of Mycophenolic Acid
PublikacjaBackground: Although Mycophenolic Acid (MPA) is applied as prodrugs in clinic as an immunosuppressant, it also possesses anticancer activity. MPA acts as Inosine-5’-Monophosphate Dehydrogenase (IMPDH) inhibitor, where the carboxylic group at the end of the side chain interacts with Ser 276 of the enzyme via hydrogen bonds. Therefore, MPA derivatives with other polar groups indicated high inhibition too. On the other hand, potent...
