Molecular profiling with high throughput assays has gained utility in the management of select cancer patients and several gene expression-based assays are now marketed for improved prognostic accuracy for patients with cancer.
Alterations in microRNAs (miRNAs), a type of small non-coding RNAs, have been reported in cells/tumors subjected to radiation exposure, implying that miRNAs play an important role in cellular stress response to radiation. NCI researchers evaluated small non-coding RNAs, long non-coding RNAs (lncRNA), and mRNA, as potential non-invasive biomarkers for radiation biodosimetry. While the use of miRNAs as radiation biomarkers has been reported, the integrated use of miRNAs, mRNAs and lncRNAs to accurately determine radiation doses is novel and has not been published.
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.
The National Cancer Institute (NCI) Division of Cancer Epidemiology and Genetics (DCEG) Immunoepidemiology Branch is seeking statements of capability or interest from parties interested in collaborative research to further co-develop a gene-based diagnostic for Hepatitis C virus (HepC, HCV).
The NIH Clinical Center seeks parties interested to license a method and apparatus that can significantly improve the diagnostic performance of portable chest (CXR) and abdominal x-rays. This device (see image below) quantifies angulation of a patient to provide for a better comparison of day-to-day improvement. Potential applications include portable chest and abdominal x-rays performed at patient's hospital bedside.
Development Status:
Current methods of labeling and synthesizing RNA do not allow for multiple labels or long RNA segments to be synthesized for large RNA on a milligram scale.
The National Cancer Institute seeks parties interested in collaborative research to co-develop a method to generate RNA molecules suitable for nanoparticle and biomedical applications.
Thymoma and thymic carcinomas are a rare and poorly understood group of malignancies. Despite the growing number of biomarkers that are used for diagnosing and treating carcinomas in general, cancers of the thymus are still diagnosed, stratified and treated by a costly combination of histology, surgery and radiological procedures. The lack of qualified biomarkers associated with thymomas and thymic carcinomas has also hampered the development of targeted therapies.
The NCI Radiation Oncology Branch and the NHLBI Laboratory of Single Molecule Biophysics seek parties to co-develop fluorescent nanodiamonds for use as in vivo and in vitro optical tracking probes toward commercialization.
HCC is the most frequent malignant tumor in the liver and the third leading cause of cancer death worldwide. A progressive sequence of somatic mutations and epigenetic changes of oncogenes or tumor suppressor genes are believed to cause tumor development. However, high genomic instability in tumors causes the accumulation of genomic aberrations that do not contribute to tumor progression. Therefore, it is important to distinguish between ''driver'' mutations that are functionally important and ''passenger'' mutations that do not provide a selective advantage to the tumor cells.
