COVID-19 signalome: Pathways for SARS-CoV-2 infection and impact on COVID-19 associated comorbidity.

The COVID-19 pandemic has been the focus of research the past two years. The major breakthrough was made by discovering pathways related to SARS-CoV-2 infection through cellular interaction by angiotensin-converting enzyme (ACE2) and cytokine storm. The presence of ACE2 in lungs, intestines, cardiovascular tissues, brain, kidneys, liver, and eyes shows that SARS-CoV-2 may have targeted these organs to further activate intracellular signalling pathways that lead to cytokine release syndrome. It has also been reported that SARS-CoV-2 can hijack coatomer protein-I (COPI) for S protein retrograde

Emerging Roles of Mesenchymal Stem/Stromal-Cell-Derived Extracellular Vesicles in Cancer Therapy.

Despite the tremendous efforts of many researchers and clinicians, cancer remains the second leading cause of mortality worldwide. Mesenchymal stem/stromal cells (MSCs) are multipotent cells residing in numerous human tissues and presenting unique biological properties, such as low immunogenicity, powerful immunomodulatory and immunosuppressive capabilities, and, in particular, homing abilities. Therapeutic functions of MSCs are mediated mostly by the paracrine effect of released functional molecules and other variable components, and among them the MSC-derived extracellular vesicles (MSC-EVs)

Multiple myeloma, a quintessential malignant disease of aging: a geroscience perspective on pathogenesis and treatment.

Multiple myeloma (MM) is an incurable plasma cell malignancy, which is predominantly a disease of older adults (the median age at diagnosis is 70 years). The slow progression from asymptomatic stages and the late-onset of MM suggest fundamental differences compared to many other hematopoietic system-related malignancies. The concept discussed in this review is that age-related changes at the level of terminally differentiated plasma cells act as the main risk factors for the development of MM. Epigenetic and genetic changes that characterize both MM development and normal aging are highlighted

Targeting Non-coding RNA for Glioblastoma Therapy: The Challenge of Overcomes the Blood-Brain Barrier.

Glioblastoma (GBM) is the most malignant form of all primary brain tumors, and it is responsible for around 200,000 deaths each year worldwide. The standard therapy for GBM treatment includes surgical resection followed by temozolomide-based chemotherapy and/or radiotherapy. With this treatment, the median survival rate of GBM patients is only 15 months after its initial diagnosis. Therefore, novel and better treatment modalities for GBM treatment are urgently needed. Mounting evidence indicates that non-coding RNAs (ncRNAs) have critical roles as regulators of gene expression. Long non-coding

Genetic Regulation of Tryptase Production and Clinical Impact: Hereditary Alpha Tryptasemia, Mastocytosis and Beyond.

Tryptase is a serine protease that is predominantly produced by tissue mast cells (MCs) and stored in secretory granules together with other pre-formed mediators. MC activation, degranulation and mediator release contribute to various immunological processes, but also to several specific diseases, such as IgE-dependent allergies and clonal MC disorders. Biologically active tryptase tetramers primarily derive from the two genes TPSB2 (encoding β-tryptase) and TPSAB1 (encoding either α- or β-tryptase). Based on the most common gene copy numbers, three genotypes, 0α:4β, 1α:3β and 2α:2β, were defi

A malignant symbiosis: The neuro-metabolic symphony rewires the tumor microenvironment.

Emerging evidence in cancer neuroscience has established a reciprocal bidirectional loop between neural signaling and tumor metabolism as a central driver of malignant progression. This review critically evaluates bidirectional neuro-metabolic symbiosis and its profound implications for overcoming treatment refractoriness. We first analyzed the anterograde mechanism, in which peripheral nerve terminals and systemic endocrine factors impose distinct metabolic dependencies on malignant and stromal cell populations. By forcing alterations in nutrient utilization pathways, these neural cues create

Ginsenoside-Mediated Ferroptosis Regulation: Bidirectional Effects and Therapeutic Potential in Diseases.

Notably, certain ginsenoside components exhibit distinct bidirectional and context-dependent regulatory effects on ferroptosis depending on the disease setting. In aberrantly proliferating or activated cells, ginsenosides function as ferroptosis inducers, whereas in damaged quiescent cells of normal tissues, they act as ferroptosis inhibitors. The pro-ferroptotic effect is predominantly observed in cells characterized by abnormal proliferation or activation, such as cancer cells and activated hepatic stellate cells in liver fibrosis. In this context, ginsenosides modulate key iron metabolism p
