Gene model for the ortholog of in .

Gene model for the ortholog of glycogen synthase ( ) in the May 2017 (Princeton ASM75419v2/DsimGB2) Genome Assembly (GenBank Accession: GCA_000754195.3 ). This ortholog was characterized as part of a developing dataset to study the evolution of the Insulin/insulin-like growth factor signaling pathway (IIS) across the genus using the Genomics Education Partnership gene annotation protocol for Course-based Undergraduate Research Experiences.

Combination therapy of an orthotopic renal cell carcinoma model using intratumoral vector-mediated costimulation and systemic interleukin-2.

Purpose: Interleukin (IL)-2 therapy is currently used for therapy of renal cell carcinoma (RCC). However, it is only effective in approximately 10% to 15% of patients, showing a need for additional therapies. We have previously described a replication-defective fowlpox vector encoding three costimulatory molecules (B7-1, ICAM-1, and LFA-3), designated rF-TRICOM.

Educational attainment as a proxy for cognitive ability in selection: effects on levels of cognitive ability and adverse impact.

The authors examined the differences in mean level of cognitive ability and adverse impact that can be expected when selecting employees solely on educational attainment as a proxy for cognitive ability versus selecting employees directly on cognitive ability. Selection using cognitive ability worked as a more efficient cognitive screen. Imposing an educational attainment standard of at least 1 year of college, though, did result in noticeably higher levels of cognitive ability in potential applicant pools than did random selection, meaning that educational attainment does work as a cognitive screen.

Induction of transplantable mouse renal cell cancers by streptozotocin: in vivo growth, metastases, and angiogenic phenotype.

Interleukin-2-based regimens of biological therapy have shown some clinical promise for the treatment of kidney cancer in humans, although the mechanisms responsible for tumor regression occurring in these patients remain unclear. Preclinical insight into these mechanisms is limited by a paucity of orthotopic animal models of kidney cancer. We have used streptozotocin, an antibiotic and diabetogenic nitrosamine compound derived from Streptomyces achromogenes to induce new kidney tumors in BALB/c mice.

Primary hepatocytes from mice treated with IL-2/IL-12 produce T cell chemoattractant activity that is dependent on monokine induced by IFN-gamma (Mig) and chemokine responsive to gamma-2 (Crg-2).

The IFN-gamma-inducible proteins monokine induced by IFN-gamma (Mig) and chemokine responsive to gamma-2 (Crg-2) can contribute to IL-12-induced antiangiogenic and leukocyte-recruiting activities, but the extent to which leukocytes vs parenchymal cells in different organs contribute to the production of these molecules remains unclear. The results presented herein show that IFN-gamma-dependent induction of Mig and Crg-2 gene expression can occur in many nonlymphoid organs, and these genes are rapidly induced in purified hepatocytes isolated from mice treated with IL-2 plus IL-12, or from Hepa 1-6 hepatoma cells treated in vitro with IFN-gamma. In addition to depending on IFN-gamma, the ability of IL-12 or IL-2/IL-12 to induce Mig and Crg-2 gene expression in purified hepatocytes also is accompanied by the coordinate up-regulation of the IFN-gamma R alpha and beta-chains, in the absence of IL-12R components.

Complete regression of established spontaneous mammary carcinoma and the therapeutic prevention of genetically programmed neoplastic transition by IL-12/pulse IL-2: induction of local T cell infiltration, Fas/Fas ligand gene expression, and mammary epithelial apoptosis.

Using a novel transgenic mouse model of spontaneous mammary carcinoma, we show here that the IL-12/pulse IL-2 combination can induce rapid and complete regression of well-established autochthonous tumor in a setting where the host immune system has been conditioned by the full dynamic process of neoplastic progression and tumorigenesis. Further, this regimen inhibits neovascularization of established mammary tumors, and does so in conjunction with potent local induction of genes encoding the IFN-gamma- and TNF-alpha-inducible antiangiogenic chemokines IFN-inducible protein 10 and monokine induced by IFN-gamma. In contrast to untreated juvenile C3(1)TAg mice in which histologically normal mammary epithelium predictably undergoes progressive hyperplasia, atypical changes, and ultimately transition to overt carcinoma, the current studies also demonstrate a unique preventative therapeutic role for IL-12/pulse IL-2.

Administration of recombinant human IL-7 to mice alters the composition of B-lineage cells and T cell subsets, enhances T cell function, and induces regression of established metastases.

These studies investigate the effects of exogenously administered recombinant human IL-7 (rhIL-7) on mouse leukocyte subsets in vivo in normal and tumor-bearing mice. The administration of rhIL-7 to normal mice caused a pronounced leukocytosis (three- to fivefold increase over background) in the spleen and lymph nodes, with B-lineage and T cells, NK cells, and macrophages all being increased. CD8+ T cells increased disproportionately, such that the CD4 to CD8 ratio decreased dramatically.

Prevention of acute chemotherapy-induced death in mice by recombinant human interleukin 1: protection from hematological and nonhematological toxicities.

Previous studies have demonstrated that interleukin 1 (IL-1) can protect most mice from the acute lethal toxicity mediated by high doses of radiation and/or some chemotherapeutic drugs. The results presented herein demonstrate that the pretreatment of mice with recombinant human interleukin 1 alpha (rhIL-1 alpha) protects mice from the lethal effects of several myelotoxic chemotherapeutic drugs, including 5-fluorouracil (5FUra), cyclophosphamide, cis-diammine(1,1-cyclobutanedicarboxylato)platinum(II), and 1,3-bis-(2-chloroethyl)-1-nitrosourea. However, pretreatment with rhIL-1 alpha was not effective against the acute lethal toxicity generated by doxorubicin and cisplatin.

Flavone acetic acid directly induces expression of cytokine genes in mouse splenic leukocytes but not in human peripheral blood leukocytes.

Flavone-8-acetic acid (FAA) is a flavonoid drug that augments mouse natural killer activity, induces cytokine gene expression, and synergizes with recombinant interleukin 2 for the treatment of murine renal cancer. However, FAA has been largely inactive in human clinical trials. In the present study we investigated the ability of FAA treatment to directly induce cytokine mRNA expression in total mouse splenic leukocytes and selected leukocyte subsets, as well as in total human peripheral blood leukocytes.

In vivo distribution and cytokine gene expression by enriched mouse LAK effector cells.

Lymphokine activated killer (LAK) cells administered in combination with interleukin 2 (IL2) can mediate antitumor activity in tumor-bearing mice and advanced cancer patients. Relatively little is known about the mechanism by which adoptively transferred LAK cells plus IL2 mediate these antitumor effects in vivo, and it remains unclear to what extent the actual LAK effector cells can accumulate in tumors. In the present study, enriched cytolytic LAK effector cells were obtained by fractionation of bulk LAK cell cultures on Percoll density gradients.

Augmentation of mouse liver-associated natural killer activity by biologic response modifiers occurs largely via rapid recruitment of large granular lymphocytes from the bone marrow.

A variety of biologic response modifiers (BRM) can potently augment NK activity in nonlymphoid organs. By using the liver as a model organ, we have shown that this augmentation of organ-associated NK activity is coincident with a 10- to 15-fold increase in the number of large granular lymphocytes (LGL) which can be isolated. The present study was designed to investigate the mechanism by which BRM induce this increase in liver-associated LGL and the coincident increase in hepatic NK activity.
