Turkish Journal of Biology

Previously, it was shown that human TWIST1 (basic helix-loop-helix (b-HLH) is phosphorylated by Akt kinase at S42, T121, and S123. To show in vivo effect of these phosphorylations, we created mouse TWIST1 expression vector and converted the codons of S42, T125, and S127 to unphosphorylatable alanine and phosphorylation mimicking Glutamic acid. We hypothesized that alanine mutants would inhibit the metastatic ability of 4T1 cells while glutamic acid mutants would convert nonmetastatic 67NR cells into metastatic phenotype. To confirm this hypothesis, we created metastatic 4T1 and nonmetastatic 67NR cells expressing alanine mutants and glutamic acid mutants mouse TWIST1, respectively. Then, we …

MEIS proteins are historically associated with tumorigenesis, metastasis, and invasion in cancer. MEIS and associated PBXHOX proteins may act as tumor suppressors or oncogenes in different cellular settings. Their expressions tend to be misregulated in various cancers. Bioinformatic analyses have suggested their upregulation in leukemia/lymphoma, thymoma, pancreas, glioma, and glioblastoma, and downregulation in cervical, uterine, rectum, and colon cancers. However, every cancer type includes, at least, a subtype with high MEIS expression. In addition, studies have highlighted that MEIS proteins and associated factors may function as diagnostic or therapeutic biomarkers for various diseases. Herein, MEIS proteins and associated factors in …

Sex Effect On The Correlation Of Immunoglobulin G Glycosylation With Rheumatoid Arthritis Disease Activity, Altan Ercan Jan 2020

Sex Effect On The Correlation Of Immunoglobulin G Glycosylation With Rheumatoid Arthritis Disease Activity, Altan Ercan

Turkish Journal of Biology

Rheumatoid arthritis (RA) is a chronic autoimmune disease which affects females more than males with a presence of autoantibodies. Immunoglobulin G (IgG) produced by adaptive arm has 2 functional domains, Fc and Fab. The Fc domain binds Fc gamma receptors and C1q proteins of the innate arm. Therefore, the IgG Fc domain serves as a bridge between the innate and adaptive arms and is regulated by an evolutionarily conserved N-glycosylation with variable structures. These glycans are classified as agalactosylated G0, monogalactosylated G1, and digalactosylated G2, which are further modified by core-fucosylation (F) and bisecting N-acetylglucosamine (B) moieties such as G0F …

Expression Of Soluble, Active, Fluorescently Tagged Hephaestin In Cos And Cho Cell Lines, Eli̇f Si̇bel Aslan, Kenneth N. White, Basharut A. Syed, Kaila S. Srai, Robert W. Evans

Turkish Journal of Biology

Hephaestin (Hp) is a trans-membrane protein, which plays a critical role in intestinal iron absorption. Hp was originally identified as the gene responsible for the phenotype of sex-linked anaemia in the sla mouse. The mutation in the sla protein causes accumulation of dietary iron in duodenal cells, causing severe microcytic hypochromic anaemia. Although mucosal uptake of dietary iron is normal, export from the duodenum is inhibited. Hp is homologous to ceruloplasmin (Cp), a member of the family of multi copper ferroxidases (MCFs) and possesses ferroxidase activity that facilitates iron release from the duodenum and load onto the serum iron transport …
