Although hormone receptor-positive (HR+) breast cancer accounts for over 70% of cases, 20%-30% of patients still experience relapse despite endocrine therapies such as tamoxifen. Recurrence is also observed in HER2+ breast cancer, even with HER2-targeted antibodies and antibody-drug conjugates (ADCs), the use of which can be limited by adverse effects such as interstitial lung disease.

Kong’s Pharmaceutical Co. has divulged Ras-related C3 botulinum toxin substrate 1 (RAC1; TC25) inhibitors reported to be useful for the treatment of cancer and neurologic disorders.

Chinese University of Hong Kong has identified peptides acting as serine/arginine-rich protein-specific kinase 1 (SRSF protein kinase 1; SRPK1) inhibitors reported to be useful for the treatment of lung cancer, breast cancer, coronavirus acute respiratory syndrome, hepatitis and herpes viral infections.

Approaches that recruit and activate tumor-infiltrating T cells could help reshape the immunosuppressive tumor microenvironment, making immunotherapy more effective for patients with microsatellite stability and low microsatellite instability colorectal cancers. Oncolytic viruses can offer an alternative to help stimulate the antitumor immunity in ‘cold’ tumors.
