Peptide Hydrogels for Rate-Controlled Delivery of Therapeutics

Hydrogels represent an attractive controlled drug-delivery system that have been used in various clinical applications, such as: tissue engineering for wound healing, surgical procedures, pain management, cardiology, and oncology. High-water content of hydrogels confers tissue-like physical properties and the crosslinked fibrillar network enables encapsulation of labile small molecule drugs, peptides, proteins, nucleic acids, proteins, nanoparticles, or cells.

A Viral Exposure Signature to Define and Detect Early Onset Hepatocellular Carcinoma

Early detection of liver cancer, such as hepatocellular carcinoma (HCC), is key to improve cancer-related mortality. More than 800,000 people are diagnosed with this cancer each year throughout the world. Liver cancer is also a leading cause of cancer deaths worldwide, accounting for more than 700,000 deaths each year. Currently, millions of Americans and possibly billions in the world are considered at risk for developing liver cancer.

T cell Receptors Which Recognize Mutated EGFR

Epidermal growth factor receptor (EGFR) is a transmembrane protein involved in cell growth and proliferation. Mutations in this protein can lead to overexpression, causing several types of cancer; notably, non-small cell lung cancer (NSCLC). For example, mutations in EGFR are found in up to 50% of NSCLC patients and the E746-A750 deletion accounts for 30-40% of such EGFR mutations. Currently, there are no available therapeutics that specifically target the E746-A750 deletion. 

Human T Cell Receptors for Treating Cancer

T cell receptors (TCRs) are proteins that recognize antigens in the context of infected or transformed cells and activate T cells to mediate an immune response and destroy abnormal cells. TCRs consist of two domains, one variable domain that recognizes the antigen and one constant region that helps the TCR anchor to the membrane and transmit recognition signals by interacting with other proteins. When a TCR is stimulated by an antigen, such as a tumor antigen, some signaling pathways activated in the cell lead to the production of cytokines, which mediate the immune response.

Highly Soluble Pyrimido-Dione-Quinoline Compounds: Small Molecules that Stabilize and Activate p53 in Transformed Cells

The tumor-suppressor p53 protein plays a major role in tumor development. Most human cancers fail to normally activate wild-type p53, which is at least partly responsible for the unregulated growth of cancer cells and their failure to undergo apoptosis. While many chemotherapeutics enhance p53 levels, their non-specific DNA damage (genotoxicity) causes unfavorable side effects.
 

Efficient Methods to Prepare Hematopoietic Progenitor Cells in vitro for Therapeutic Use

Hematopoietic progenitor cells (HPC) are multi-potent hematopoietic lineage cells that can differentiate into any type of blood cell, including but not limited to erythrocytes, T cells, B cells, and natural killer cells. As such, they have high therapeutic potential in the fields of regenerative medicine and cancer immunotherapy, especially when generated from patient-derived induced pluripotent stem cells (iPSC). Currently, the most efficient protocol to produce HPCs is co-culturing human iPSCs (hiPSC) with mouse stromal cells as a two-dimensional (2D) monolayer.

Inhibition of T Cell Lactate Dehydrogenase (LDH) ex vivo Enhances the Anti-tumor Efficacy of Adoptive T Cell Therapy

Adoptive T cell therapy (ACT) with tumor infiltrating lymphocytes (TIL), T cell receptor (TCR) and Chimeric Antigen Receptor (CAR) engineered T cells, or hematopoietic stem cell transplantation, is a promising new approach to cancer treatment. ACT harnesses an individual's adaptive immune system to fight against cancer, with fewer side-effects and more specific anti-tumor activity. Despite their promise of ACT as curative, these therapies are often limited by the persistence and robustness of the responses of the T cells to the cancer cells.

Non-invasive diagnostic and prognostic assay for early stage lung cancer

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.
