Method and Device for Selectively Labeling RNA
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.
Exposure to ionizing radiation or agents that induce DNA double-stranded breaks (DSBs), which is one of the most damaging types of lesions in DNA, can result in damage to cells and/or tissues. Thiscan lead to illness (i.e., Acute Radiation Syndrome, Cancer) or death. Identifying the amount of exposure to a DNA DSB-causing agent can be useful in determining the need for further testing, avoidance or modification of certain medical procedures, and/or types of medical treatments.
Available for licensing from the Laboratory of Cancer Biology and Genetics of the National Cancer Institute (NCI) is a novel gene signature of thirty-seven drug-responsive genes that links changes in gene expression to the clinically desirable outcome of improved overall survival. Expression of these genes has been linked to prognosis in several cancers, including, but not limited to: multiple myeloma, melanoma, and lung and breast cancers.
In the United States alone, one of four cancer deaths occur from lung cancer and there are over 8 million individuals considered to be at high-risk due to cigarette smoking and other behaviors. It's well known that early detection of cancer significantly improves survival of this disease, however a lack of lung cancer screenings and analysis precludes fast results at a low cost.
Over the past decades, taxanes such as paclitaxel and docetaxel have emerged as effective chemotherapy agents for breast cancer and other malignancies. Taxanes are effective in many patients, however, not all patients benefit from this type of chemotherapy. A significant need remains for a means of predicting clinical outcome from taxane-based chemotherapy.
Hepatitis C virus (HCV) is a major global health problem with an estimated 58 million infections in 2019. However, most HCV infections go undiagnosed due to the lack of clinical symptoms or for lack of access to simple and affordable diagnostic testing. It is estimated that only 21% and 61% of people with a chronic HCV infection have been diagnosed, worldwide and in the United States, respectively.
