The MUC-1 tumor associated antigen has been shown to be overexpressed and/or underglycosylated in a wide range of human cancers. The C-terminus region of MUC-1 (MUC-1C) has been shown to be an oncogene and has been associated with a more aggressive phenotype in several different cancers.
Polo-like kinase 1 (Plk1), a member of the Polo-like kinase family, plays a critical role in regulating mitosis and cell cycle progression. Aberrant expression of Plk1 has been observed in a variety of human cancers, and it is known to be associated with tumorigenesis as well as poor prognosis in cancer patients. Unlike normal cells, some cancer cells are dependent on augmented Plk1 levels to remain viable and are killed when Plk1 function is attenuated.
Ovarian cancer is one of the most common and lethal types of gynecological malignancies worldwide, accounting for approximately 295,000 new cases and 185,000 deaths annually. The high lethality rate is due to multiple reasons, including recurrence and the resistance of recurrent tumors to chemotherapy. Cell line models are crucial for preclinical cancer studies, to identify mechanisms of disease, to study drug resistance, and to screen for candidate therapeutics.
Tyrosyl-DNA phosphodiesterase 2 (TDP2) is an enzyme that playings a critical role in repairing nucleic acid lesions, namely by repairing trapped DNA cleavage complexes. TDP2 repairs topoisomerase (TOP2)-mediated DNA damage induced by chemotherapeutic agents and removes endogenous TOP2-DNA cleavage complexes. Further, TDP2 deficiency potentiates the antiproliferative activity of TOP2 inhibitors. This suggest that combination therapies consisting of TDP2 and TOP2 inhibitors have a synergistic effect on tumor tissues.
The Eunice Kennedy Shriver National Institute of Child Health and Human Development, Section on Molecular Neurobiology is seeking statements of capability or interest from parties interested in collaborative research to further evaluate or commercialize specific rabbit monoclonal antibodies generated against the ErbB4 receptor (also known as HER4) that have been validated for specificity using tissue sections and extracts from ErbB4 knockout mice.
The COVID-19 pandemic is a worldwide public health crisis with over 100 million confirmed cases and 2.4 million deaths as of February 2021. COVID-19 is caused by a novel coronavirus called SARS-CoV-2. SARS-COV-2 infects hosts via its spike (S) protein. The S protein contains the receptor binding domain (RBD) that binds to the angiotensin converting enzyme 2 (ACE2) receptor on human cells to facilitate viral entry and infection. There are few therapeutics available for COVID-19 patients that directly target SARS-CoV-2.
Optical traps (optical tweezers) have a focused laser beam able to trap a small bead at its focus, and are used to measure the microrheology of gels and other materials. They have recently been used to characterize properties of living cells, however issues of image spatial resolution and limited depth of interrogation have prevented application of an optical trap to measure microrheological (flow of matter) properties in complex (non-uniform) materials, such as multi-cellular systems or living organisms.
Lassa Hemorrhagic Fever (LHF) is a serious disease caused by infection with Lassa virus (LASV) – highly prevalent in West Africa and spreading globally. LASV is associated with high morbidity and mortality rates, annually infecting 100,000 to 300,000 individuals and causing 5,000 deaths. Developing prophylactics and treatment for LASV is difficult due to challenges in inducing neutralizing antibodies and producing their target, the LASV glycoprotein trimer (GPC).
The National Cancer Institute's Laboratory of Cell Biology is seeking statements of capability or interest from parties interested in collaborative research to further develop, evaluate, or commercialize the use of DKK1 to treat abnormal pigmentation of the skin or to regulate hair growth.
Mesothelin is a cell surface protein that is highly expressed in aggressive cancers, such as malignant mesothelioma, ovarian cancer and pancreatic cancer, lung cancer, breast cancer, cholangiocarcinoma, bile duct carcinoma and gastric cancer. Because of this selective expression, mesothelin is an excellent candidate for targeted therapeutics, such as monoclonal antibodies (mAbs) and chimeric molecules. Current anti-mesothelin therapeutic mAb candidates bind to an epitope in Region I of mesothelin. Unfortunately, Region I contains the interaction site MUC16/CA125, a mesothe
