The vacuolar ATPase (v-ATPase) is essential for acidification of intracellular organelles, including synaptic vesicles. Its activity is controlled by cycles of association and dissociation of the ATP hydrolysis (V) and proton transport (V) multi-protein subunits. Mutations in genes coding for both v-ATPase subunits and TBC1D24 cause neurodevelopmental disorders with overlapping syndromes; therefore, it is important to investigate their potentially interrelated functions.

Introduction: Immune checkpoint inhibitor (ICI)-based immunotherapy targeting programmed cell death 1 (PD-1) or its ligand 1 (PD-L1) has radically changed the management of many types of solid tumors including non-small cell lung cancer (NSCLC). Many clinical trials have demonstrated that ICIs improve the survival and the quality of life of patients with advanced non oncogene NSCLC as compared to standard therapies. However, not all patients achieve a clinical benefit from this immunotherapeutic approach.

Kristen rat sarcoma viral oncogene homolog (KRAS) mutations play a major role in the carcinogenesis of many types of solid tumors including non-small cell lung cancer (NSCLC). Among KRAS mutations, p.G12C single-nucleotide variant (KRAS) is the most frequently reported in NSCLC patients, with a prevalence of about 12-13 %.

Article Synopsis
  • Neurons rely on autophagy, a process that recycles damaged proteins and organelles, to maintain cellular health and function over their long lifespan, particularly in the face of challenges like starvation.
  • Research shows that a neuron-specific protein called APache plays a critical role in autophagy by helping transport autophagosomes back to the cell body, affecting synaptic health.
  • Silencing APache disrupts this transport, leading to an accumulation of autophagosomes at synapses which may contribute to early neurodegenerative issues linked to impaired autophagy.
