Novel Small Molecule Inhibitors of Tyrosyl-DNA Phosphodiesterase 1 (TDP1) for Treatment of Solid Tumors

Topoisomerase 1 (TOP1) is an essential enzyme that plays a critical role in DNA transcription and replication. TOP1 inhibitors are a known class of anti-cancer agents that work to interrupt DNA replication in cancer cells, causing cell death. Since the discovery of the TOP1 inhibitor camptothecin (CPT) from plant extracts more than 60 years ago, two CPT analogs (irinotecan and topotecan) were approved by the FDA for cancer treatment. Tyrosyl-DNA phosphodiesterase 1 (TDP1) is an enzyme involved in DNA repair created when TOP1 is inhibited.

Cell Lines that Constitutively Express High-Frequency KRAS and P53 Mutations and Human Leukocyte Antigens (HLAs)

Adoptive cell therapy (ACT) is a breakthrough form of cancer immunotherapy that utilizes tumor infiltrating lymphocytes (TILs) or genetically engineered T cells to attack tumor cells through recognition of tumor-specific antigens. A major hurdle in the development of ACT is the identification and isolation of T cells that recognize antigens that are expressed by tumor cells but not by healthy tissues. Current methods to identify such T cells involve extracting autologous antigen presenting cells (APCs) from patients in an expensive, laborious, and time-consuming process.

T Cell Receptors Targeting BRAF V600E Mutation for Cancer Immunotherapy

BRAF is an oncogene that encodinges a serine-threonine kinase (B-Raf kinase) important in regulating cell growth and differentiation. Spontaneous mutations in the BRAF gene allow cells to continuously divide, leading to the development of cancer. A substitution of glutamic acid for valine at amino acid number 600 (designated V600E) accounts for 90% of BRAF mutations and is a driver of many cancers. The V600E mutation is present in ~3% of all cancer cases, representing a patient population of 540,000 patients per year.

Automatic System and Method for Tissue Sectioning, Staining, and Scanning

Computer and imaging technologies led to the development of digital pathology and the capture and storage of pathological specimens as digitally formatted images. The use of artificial intelligence (AI) in digital pathology, such as in three-dimensional (3D) reconstruction, requires analyses of high volumes of data. This results in increased demands for processing and acquisition of digital images of pathology samples. Increased usage cannot be met by the time-consuming, manual, and laborious methods currently used.

Neoantigen T Cell Therapy with Neoantigen Vaccination as a Combination Immunotherapy Against Cancer

Adoptive cell therapy (ACT) is a breakthrough form of cancer immunotherapy that utilizes autologous, antitumor T cells to attack tumors through recognition of tumor-specific mutations, or neoantigens. A major hurdle in the development of ACT is the exhausted phenotype exhibited by many neoantigen-specific T cells, which limits their efficacy and prevents a sustained immune response. 

Bacteriophage Based-Vaccine System

Vaccines have become one of the most important tools in the fight against cancers and infectious diseases. However, some vaccines have shown limitations due to their high cost and low immune responses. To overcome these limitations, bacteriophages were proposed for the development of more cost-effective, immunogenic vaccines. Phages have shown a strong ability to activate induced and adaptive immune systems. The genome of these viral particles can be engineered, and their surface proteins can be exploited for antigen display.

La Protein as a Novel Regulator of Osteoclastogenesis

Millions of patients in the United States are afflicted by a host of bone diseases caused by osteoclast (specialized calls arising from the macrophage/monocyte lineage) dysfunction. Diseases include Paget’s disease, osteoporosis, fibrous dysplasia and osteolytic bone metastasis. The current standard of care for these diseases uses broad-spectrum therapies that either coat the skeletal system or inhibit osteoclast development in an effort to modulate osteoclastogenesis.

Therapeutics Against Pathogenic Coronaviruses

The COVID-19 pandemic is a worldwide public health crisis with over 440 million confirmed cases and 6.0 million deaths as of March 2022. COVID-19 is caused by a novel coronavirus called Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). While there are several vaccines available for COVID-19, there are few therapeutics available that specifically target SARS-CoV-2. Middle East respiratory syndrome coronavirus (MERS-CoV) is less understood than SARS-CoV-2. MERS-CoV patients have a 65% long-term survival rate, according the World Health Organization (WHO).
