Ubiquitin specific protease 7 – a good target for cancer therapy

Ubiquitin specific protease 7 (USP7) is a deubiquitinase, an enzyme that removes ubiquitin a 76 amino acid protein that is added onto lysines in the target protein. Proteins that are mono, or poly (up to 10 residues), ubiquitinated are taken to the proteasome for destruction. Continue reading

The levels of immune cells within ovarian cancer tumors correlate with survival

Researches with the Ovarian Tumor Tissue Analyses Consortium analyzed the CD8+ (cytotoxic T-cell) content of tumors from 5,500 patients and compared them with clinical outcome. The analysis was large enough to allow for comparison by histologic subtype – endometrioid, clear cell, mucinous, and low-grade serous ovarian cancer, as well as high-grade serous ovarian cancer. Included in the sample were 3,200 high grade serous ovarian cancers. Continue reading

Etinostat blocks Treg activity via FOXP3 suppression

Histone deacetylase (HDAC) inhibitors block the removal of acetyl groups from histone proteins. Since acetylation of histones puts chromatin in a more favorable condition for transcription, HDAC inhibitors maintain this favorable state. HDAC inhibitors have been approved for use in cutaneous T-cell lymphoma. They act by sustaining transcription of tumor suppressor genes, which leads to cell cycle arrest and apoptosis.

Immatics and MD Anderson Collaborate on IL-21 for Cancer Immunotherapy

Immatics, a German biotechnology company has established a subsidiary in Houston, TX to collaborate with MD Anderson on overcoming some of the limitations to the adoptive T cell therapies now in the immuno-oncology pipeline. The collaboration covers the use of cytokine IL-21 to expand high-quality T cell batches, particularly those generated by CAR-T (chimeric antigen receptor T-cell) and related approaches.

Cancer Immunotherapy – Combining Anti-CCR4 & Anti-PD-1; and CEACAM1 (TIM-3)

A collaboration between Bristol-Myers Squibb and Kyowa Hakko Kirin to test a combination of Kyowa’s Poteligeo (mogamulizumab), an anti-CCR4 antibody, and BMS’ Opdivo (nivolumab) in a Phase I/II trial in advanced or metastatic solid tumors was announced. Also, Merck announced the acquisition of cCAM Biotherapeutics for $605MM for its CM-24 monoclonal antibody that target CEACAM1. Continue reading
