Objective(s): In the present study, we investigated the effect of ischemic preconditioning (IPC) on c-myb immunoreactivity as well as neuronal damage/death after a subsequent lethal transient ischemia in gerbils. Materials and Methods: IPC was subjected to a 2 min sublethal ischemia and a lethal transient ischemia was given 5 min transient ischemia. The animals in all of the groups were given ...
Background: Pomegranate fruit (Punica granatum L.) is a rich source of anthocyanin pigments resulting in vibrant colours and anti-oxidant contents. Although the intensity and pattern of anthocyanin biosynthesis in fruit are strongly influenced by R2R3-MYB transcription factors, little is known about the regulation and role of MYB in anthocyanin pathway of pomegranate. Objectives: The present st...
The c-myb proto-oncogene product (c-Myb) regulates proliferation and differentiation of hematopoietic cells. Recently we have shown that c-Myb is degraded in response to Wnt-1 stimulation via a pathway involving TAK1 (TGF-beta-activated kinase), HIPK2 (homeodomain-interacting protein kinase 2), and NLK (Nemo-like kinase). NLK and HIPK2 bind directly to c-Myb and phosphorylate c-Myb at multiple ...

Three members of the human myb gene family (c-myb, A-myb, and B-myb) encode transcriptional regulators that can bind to specific DNA sequences. High levels of c-myb expression are usually found in immature hemopoietic cells, but the B-myb is more commonly expressed in many types of cells. To understand the regulation of the activity of B-myb gene product (B-Myb), its functional domains were ana...
The c-myb proto-oncogene product (c-Myb) is degraded in response to Wnt-1 signaling via a pathway involving TAK1 (transforming growth factor-beta-activated kinase 1), HIPK2 (homeodomain-interacting protein kinase 2), and NLK (Nemo-like kinase). NLK directly binds to c-Myb, which results in the phosphorylation of c-Myb at multiple sites, and induces its ubiquitination and proteasome-dependent de...
Gene duplication is an important means of generating new genes. The major mechanisms by which duplicated genes are preserved in the face of purifying selection are thought to be neofunctionalization, subfunctionalization, and increased gene dosage. However, very few duplicated gene families in vertebrate species have been analyzed by functional tests in vivo. We have therefore examined the thre...
The myb gene family encodes proteins characterized by a highly conserved DNA-binding domain and functions as transcription regulators. There are three myb genes in animals with three Myb-motif repeats, namely c-myb, A-myb, and B-myb. By contrast, plants possess an abundance of myb genes, the majority of which are of the type R2R3 (with two Myb-motifs). Few plant myb genes are of the type R1R2R3...
