Abstract Background Baculoviruses can be inactivated by ultraviolet (UV) light, which limits their application as an efficient biopesticide. In attempt to enhance virus resistance UV inactivation, a photolyase gene, isolated from Spodoptera litura granulovirus (SpliGV), was expressed in deficient littoralis nucleopolyhedrovirus (SpliNPV) and the infectivity of recombinant expressing phr gene de...
SOCS1 is an SH2-containing protein that is primarily expressed in thymocytes in a cytokine- and T cell receptor-independent manner. SOCS1 deletion causes perinatal lethality with death by 2-3 weeks. During this period thymic changes include a loss of cellularity and a switch from predominantly CD4+ CD8+ to single positive cells. Peripheral T cells express activation antigens and proliferate to ...
Male and female Drosophila melanogaster with special sex chromosome or special autosome constitutions were fed with the mutagenic chemicals Trenimon (2,3,5-trisethyleneimino-1,4-benzoquinone) and PDMT (1-phenyl-3, 3-dimethyltriazene) and with the toxic substance Na2PO3F (sodium monofluorophosphate). The frequency of dominant lethality was recorded among the progeny. The results clearly show tha...
The present studies determined whether clinically relevant phosphodiesterase 5 (PDE5) inhibitors interacted with clinically relevant chemotherapies to kill gastrointestinal/genitourinary cancer cells. In bladder cancer cells, regardless of H-RAS mutational status, at clinically achievable doses, PDE5 inhibitors interacted in a greater than additive fashion with doxorubicin/mitomycin C/gemcitabi...
The B-type cyclin Clb5 is involved primarily in control of DNA replication in Saccharomyces cerevisiae. We conducted a synthetic genetic array (SGA) analysis, testing for synthetic lethality between the clb5 deletion and a selected 87 deletions related to diverse aspects of cell cycle control based on GO annotations. Deletion of the spindle checkpoint genes BUB1 and BUB3 caused synthetic lethal...
