Nonthermal Plasma Boosted Dichloroacetate Induces Metabolic Shifts to Combat Glioblastoma CSCs via Oxidative Stress.

Glioblastoma (GBM) remains a formidable clinical challenge, with cancer stem cells (CSCs) contributing to treatment resistance and tumor recurrence. Conventional treatments often fail to eradicate these CSCs characterized by enhanced resistance to standard therapies through metabolic plasticity making them key targets for novel treatment approaches. Addressing this challenge, this study introduces a novel combination therapy of dichloroacetate (DCA), a metabolic modulator and nonthermal plasma to induce oxidative stress in glioblastomas.

Conserved and Unique Mitochondrial Target Sequence of TRPV4 Can Independently Regulate Mitochondrial Functions.

Though mitochondria have their own genome and protein synthesis machineries, the majority of the mitochondrial proteins are actually encoded by the nuclear genome. Most of these mitochondrial proteins are imported into specific compartments of the mitochondria due to their mitochondrial target sequence (MTS). Unlike the nuclear target sequence, the MTS of most of the mitochondrial localized proteins remain poorly understood, mainly due to their variability, heterogeneity, unconventional modes of action, mitochondrial potential-dependent transport, and other complexities.

Essential role of Hepcidin in host resistance to disseminated candidiasis.

is a leading cause of life-threatening invasive infections with up to 40% mortality rates in hospitalized individuals despite antifungal therapy. Patients with chronic liver disease are at an increased risk of candidemia, but the mechanisms underlying this susceptibility are incompletely defined. One consequence of chronic liver disease is attenuated ability to produce hepcidin and maintain organismal control of iron homeostasis.

Inactivation of Pseudovirus Expressing the D614G Spike Protein Mutation using Nitric Oxide-Plasma Activated Water.

Variants of concern (VOCs) of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) exhibit high infectivity due to mutations, particularly in the spike protein, that facilitate enhanced binding of virus to human angiotensin-converting enzyme 2 (hACE2). The D614G mutation, situated in S1-domain, promotes the open conformation of spike protein, augmenting its interaction with hACE2. Activated water neutralizes pathogens by damaging biological molecules; however, its effect on mutated SARS-CoV-2 or VOCs requires further exploration.
