Metal ions play several major roles in proteins: structural, regulatory, and enzymatic. The binding of some metal increase stability proteins or protein domains. Some can regulate various cell processes being first, second, third messengers. ions, especially transition take part catalysis many enzymes. From ten to twelve metals are vitally important for activity living organisms: sodium, potass...

Wnts are the major ligands responsible for activating Wnt signaling pathway through binding to Frizzled proteins (Fzd) as the receptors. Among these ligands, Wnt2 plays the main role in the tumorigenesis of several human cancers especially colorectal cancer (CRC). Therefore, it can be considered as a potential drug target.The aim of this study was to identify potential drug candidates ...

Background: Breast cancer is known as the most widely recognized dangerous tumors; therefore, the most common reason for mortality among all instances of harmful neoplastic illness in females. This is because the lack of specific signs and symptoms at the early stage and at the aggressive nature. Currently, breast cancer treatment such as chemotherapy, surgery and radiotherapy has not been effe...

continuous labelling of callus with h-thymidine results in intermittent peaks of h-dna per chloroplast, showing synchrony of division. the increase in h-dna could be due to several replication rounds, and the drop to successive plastid divisions without intervening dna synthesis. the level of dna-binding proteins in the chloroplast parallels the peaks of plastidal dna synthesis; such proteins c...
