ARF-P19, a novel regulator of the mammalian cell cycle

The INK4A (MTS1, CDKN2) gene encodes a specific inhibitor (InK4a-p16) of the cyclin D-dependent kinases CDK4 and CDK6. InK4a-p16 can block these kinase from phosphorylating the retinoblastoma protein (pRb), preventing exit from the G1 phase of the cell cycle. Deletions and mutations involving the gene encoding InK4a-p16, INK4A, occur frequently in cancer cells, implying that INK4a-p16, like pRb, suppresses tumor formulation. However, a completely unrelated protein (ARF-p19) arises in major part from an alternative reading frame of the mouse INK4A gene. Expression of an ARF-p19 cDNA (SEQ ID NO:1) in rodent fibroblasts induces both G1 and G2 phase arrest. Economical reutilization of protein coding sequences in this manner is without precedent in mammalian genomes, and the unitary inheritance of INK4a-p16 and ARF-p19 may reflect a dual requirement for both proteins in cell cycle control.

Cell regulatory genes, encoded products, and uses related thereto

This application describes the cloning of p63, a gene at chromosome 3q27-29, that bears homology to the tumor suppressor p53. The p63 gene encodes at least six different isotypes. p63 was detected in a variety of human and mouse tissue and demonstrates remarkably divergent activities, such as the ability to transactivate p53 reporter genes and induce apoptosis. Isotopes of p63 lacking a transactivation domain act as dominant negatives towards the transactivation by p53 and p63.

The present invention is based, at least in part, on the generation of an animal model of pancreatic adenocarcinoma which recapitulates the genetic and histological features of human pancreatic adenocarcinoma, including the initiation, maintenance, and progression of the disease. Accordingly, the present invention provides animal models of cancer, e.g., pancreatic adenocarcinoma, wherein an activating mutation of Kras has been introduced, and any one or more known or unknown tumor suppressor genes or loci, e.g., Ink4a / Arf, Ink4a, Arf, p53, Smad4 / Dpc, Lkb1, Brca2, or Mlh1, have been misexpressed, e.g., have been misexpressed leading to decreased expression or non-expression. The animal models of the invention may be used, for example, to identify biomarkers of pancreatic cancer, to identify agents for the treatment or prevention of pancreatic cancer, and to evaluate the effectiveness of potential therapeutic agents.

Human diaphanous-3 gene and methods of use therefor

The present invention is directed to the full-length cDNA sequence encoding human diaphanous-3 (DIAPH3), to DIAPH3 encoded thereby, and to fragments of DIAPH3 and the cDNA. The present invention also provides for the use of the cDNA, and of DIAPH3, as a marker of poor prognosis of breast cancer. Because DIAPH3 appears essential for proper spindle pole formation during mitosis, DIAPH3 is a useful target for screening assays designed to identify inhibitors or modulators of DIAPH3 activity, which are useful for the treatment of cancer, particularly breast cancer. Thus, the invention further provides methods of using DIAPH3, or fragments thereof, in assays to identify such compounds.

Method for therapeutic angiogenesis

InactiveUS20120107297A1Level and activity can be reducedImprove stabilityPeptide/protein ingredientsLigasesAnticarcinogenAngiogenesis Inducing Agents
The present invention relates to the E2EPF UCP-VHL interaction and the uses thereof, more precisely a method for increasing or reducing VHL activity or level by regulating UCP activity or level to inhibit cancer cell proliferation or metastasis or to increase angiogenesis. The inhibition of UCP activity is accomplished by any UCP activity inhibitor selected from a group consisting of a small interfering RNA (RNAi), an antisense oligonucleotide, and a polynucleotide complementarily binding to mRNA of UCP, a peptide, a peptide mimetics and an antibody, and a low molecular compound. In the meantime, the increase of angiogenesis is accomplished by the following mechanism; UCP over-expression is induced by a gene carrier and thus endogenous VHL is reduced, leading to the stabilization of HIF-1α which enhances VEGF activation based on the HIF-1α stabilization. The method for regulating UCP activity or level results in the increase or decrease of VHL activity or level, so that it can be applied to the development of an anticancer agent and an angiogenesis inducer.

The present invention relates generally to mutagenesis of target genes that enhances the natural mutagenic capabilities of adaptive immune cells by providing a chimeric construct that exploits the ability of molecules such as AID to stimulate diversification and the ability of a second molecule to restrict nuclear activity of the molecules and / or protect cell viability. The invention provides a method for stimulating diversification in expressed genes, such as antibody genes, using polypeptides whose nuclear activity is restricted to specific phases of the cell cycle. This method can be coupled with selection to identify B cell clones that produce, for example, antibodies of high affinity or specificity, or for developing T cells for immunotherapy. The invention provides an improved means of developing a repertoire of variant immunoglobulins and other polypeptides.
