Fungi, immunosenescence and cancer.

Fungal microbes are a small but immunoreactive component of the human microbiome, which may influence cancer development, progression and therapeutic response. Immunosenescence is a process of immune dysfunction that occurs with aging, including lymphoid organ remodeling, contributing to alterations in the immune system in the elderly, which plays a critical role in many aspects of cancer. There is evidence for the interactions between fungi and immunosenescence in potentially regulating cancer progression and remodeling the tumor microenvironment (TME).

Demethylzeylasteral inhibits oxidative phosphorylation complex biogenesis by targeting LRPPRC in lung cancer.

Targeted inhibition of mitochondrial oxidative phosphorylation (OXPHOS) complex generation is an emerging and promising cancer treatment strategy, but limited targets and specific inhibitors have been reported. Leucine-rich pentatricopeptide repeat-containing protein (LRPPRC) is an atypical RNA-binding protein that regulates the stability of all 13 mitochondrial DNA-encoded mRNA (mt-mRNA) and thus participates in the synthesis of the OXPHOS complex. LRPPRC is also a prospective therapeutic target for lung adenocarcinoma, serving as a promising target for OXPHOS inhibition.
