Optimizing autophagy modulation for enhanced TRAIL-mediated therapy: Unveiling the superiority of late-stage inhibition over early-stage inhibition to overcome therapy resistance in cancer.

Autophagy is a vital mechanism that eliminates large cytoplasmic components via lysosomal degradation to maintain cellular homeostasis. The role of autophagy in cancer treatment has been studied extensively. Autophagy primarily prevents tumour initiation by maintaining genomic stability and preventing cellular inflammation.

HIF-1α stabilization inhibits Japanese encephalitis virus propagation and neurotoxicity via autophagy pathways.

Japanese encephalitis (JE) is a widespread flavivirus that induces brain inflammation and affects the central nervous system (CNS). Deferoxamine, an iron chelator, has shown promising results in stabilizing HIF-1α, a protein that improves hypoxic conditions, offers protective effects against neurological, and neurodegenerative diseases. This study aimed to assess the impact of HIF-1α stabilization during JEV infection using SH-SY5Y neuroblastoma cell lines as a model.

Melatonin-mediated calcineurin inactivation attenuates amyloid beta-induced apoptosis.

Alzheimer's disease (AD) is the most common age-related progressive neurodegenerative disorder. The accumulation of amyloid beta-peptide is a neuropathological marker of AD. While melatonin is recognized to have protective effects on aging and neurodegenerative disorders, the therapeutic effect of melatonin on calcineurin in AD is poorly understood.

An Antidepressant Drug Increased TRAIL Receptor-2 Expression and Sensitized Lung Cancer Cells to TRAIL-induced Apoptosis.

Background: TRAIL has emerged as a promising therapeutic target due to its ability to selectively induce apoptosis in cancer cells while sparing normal cells. Autophagy, a highly regulated cellular recycling mechanism, is known to play a cell survival role by providing a required environment for the cell. Recent studies suggest that autophagy plays a significant role in increasing TRAIL resistance in certain cancer cells.

Antiviral activity of prion protein against Japanese encephalitis virus infection in vitro and in vivo.

Flaviviruses are a major cause of viral diseases worldwide, for which effective treatments have yet to be discovered. The prion protein (PrPc) is abundantly expressed in brain cells and has been shown to play a variety of roles, including neuroprotection, cell homeostasis, and regulation of cellular signaling. However, it is still unclear whether PrPc can protect against flaviviruses.
