Relieving hypoxia in the tumor microenvironment (TME) promotes innate and adaptive immunity. Our previous research demonstrated that reoxygenation of the TME promotes the phagocytosis and tumor-killing functions of tumor-associated macrophages (TAMs) by upregulating pyruvate carboxylase (PCB). However, the mechanism remains obscure.

Glioblastoma multiforme (GBM) is a devastating, aggressive primary brain tumor with poor patient outcomes and a five-year survival of less than 10%. Significant limitations to effective GBM treatment include poor drug delivery across the blood-brain barrier, drug resistance, and complex genetic tumor alterations. Gene therapy uses a mechanism different from other GBM therapies to reduce tumor growth and enhance antitumor immunity.

Chordomas are a low-to-intermediate-grade slow-growing subtype of sarcoma, but show propensity to grow and invade locally with recurrence and metastasis in 10-40% of cases. We describe the first case of spontaneous regression of a solid tumor (histologically and immunohistochemically proven chordoma) after COVID-19. A female patient with clival chordoma underwent occipitocervical fixation prior to tumor resection.

: Tamoxifen (TAM) is an anti-breast cancer drug suffering from acquired resistance development, prompting cancer relapse. Propranolol (PRO)'s repurposing for cancer therapy has gained interest. This work aimed to investigate combined TAM/PRO therapy for potentiating the anti-breast cancer activity of TAM.
