Modafinil has attracted attention for the treatment of cognitive dysfunction in disorders such as attention-deficit/hyperactivity disorder (ADHD) as well as cocaine and methamphetamine dependence. However, modafinil has relatively low affinity for binding to the dopamine transporter (DAT) to block dopamine reuptake, and is water-insoluble, thus requiring large doses to achieve pharmacological effects.
The Surgery Branch of the National Cancer Institute is seeking statements of capability or interest from parties interested in collaborative research to carry out genotypic as well as phenotypic analysis of the 888 mel cell line in order to better understand the nature of tumor cells that respond to therapy. In addition, this cell line can be used as a target of humoral or cell mediated immune responses as a part of studies characterizing the nature of immune responses directed against tumor cells.
Poly-ADP ribose polymerase-1 (PARP-1) is a critical enzyme involved in DNA repair. The inhibition of PARP has emerged as a promising strategy in cancer therapy. Numerous PARP inhibitors have been developed and advanced into clinical trials, both for use as single agents in specific patient populations and as combination therapies with various chemotherapeutics. The induction of strand break damage to DNA, as has been demonstrated in cancer cells treated with O2-arylated diazeniumdiolates, coupled with inhibition of DNA repair by PARP inhibitors, represents a novel rational
The National Cancer Institute is seeking parties interested in licensing human monoclonal antibodies (mAbs) that bind to death receptor 4 ("DR4").
The successful development of new cancer therapeutics requires reliable preclinical data that are obtained from mouse models for cancer. Human tumor xenografts, which require transplantation of human tumor cells into an immune compromised mouse, represent the current standard mouse model for cancer. Since the immune system plays an important role in tumor growth, progression and metastasis, the current standard mouse model is not ideal for accurate prediction of therapeutic effectiveness in patients.
The National Cancer Institute's Protein Expression Laboratory seeks parties interested in licensing the novel delivery of RNA to mammalian cells using virus-like particles.
Current treatments for cancer and viral infection are limited remedies that often suppress cell or viral replication rather than eliminate diseased cells entirely from the body. A further limitation is that these therapies often compromise healthy cells as well, leaving problems of recurrence and side effects.
Researchers at developed a novel therapeutic nanoparticle (NP) system harboring therapeutic small siRNA that can significantly enhance effectiveness and specificity of treatments by killing diseased cells.
The manner by which cancers evade the immune response is not well-understood. What is known is that the manner is an active process that regulates immune responses employing at least two types of suppressive cells, myeloid-derived suppressive cells and regulatory T cells (Tregs), a key subset of CD4+ T cells that controls peripheral tolerance to self- and allo-antigens. Tregs are considered to play a key role in the escape of cancer cells from anti-tumor effector T cells.
Available for commercial development is software that provides automatic visualization of features inside biological image volumes in 3D. The software provides a simple and interactive visualization for the exploration of biological datasets through dataset-specific transfer functions and direct volume rendering. The method employs a K-Means++ clustering algorithm to classify a two-dimensional histogram created from the input volume. The classification process utilizes spatial and data properties from the volume.
The National Institute on Drug Abuse's Medications Discovery Research Branch is seeking statements of capability or interest from parties interested in collaborative research to further develop, evaluate, or commercialize 4-phenylpiperazine derivatives as dopamine D3 selective ligands.
