Lactic Acid Bacteria-Derived Postbiotics as Adjunctive Agents in Breast Cancer Treatment to Boost the Antineoplastic Effect of a Conventional Therapeutic Comprising Tamoxifen and a New Drug Candidate: An Aziridine-Hydrazide Hydrazone Derivative.

Breast cancer is associated with high mortality and morbidity rates. As about 20-30% of patients exhibiting ER-positive phenotype are resistant to hormonal treatment with the standard drug tamoxifen, finding new therapies is a necessity. Postbiotics, metabolites, and macromolecules isolated from probiotic bacteria cultures have been proven to have sufficient bioactivity to exert prohealth and anticancer effects, making them viable adjunctive agents for the treatment of various neoplasms, including breast cancer. In the current study, postbiotics derived from L. plantarum and L. rhamnosus cultures were assessed on an in vitro breast cancer model as potential adjunctive agents to therapy utilizing tamoxifen and a candidate aziridine-hydrazide hydrazone derivative drug. Cell viability and cell death processes, including apoptosis, were analyzed for neoplastic MCF-7 cells treated with postbiotics and synthetic compounds. Cell cycle progression and proliferation were analyzed by PI-based flow cytometry and Ki-67 immunostaining. Postbiotics decreased viability and triggered apoptosis in MCF-7, modestly affecting the cell cycle and showing a lack of negative impact on normal cell viability. Moreover, they enhanced the cytotoxic effect of tamoxifen and the new candidate drug toward MCF-7, accelerating apoptosis and the inhibition of proliferation. This illustrates postbiotics' potential as natural adjunctive agents supporting anticancer therapy based on synthetic drugs.

Postbiotics as Molecules Targeting Cellular Events of Aging Brain-The Role in Pathogenesis, Prophylaxis and Treatment of Neurodegenerative Diseases.

Aging is the most prominent risk factor for neurodegeneration occurrence. The most common neurodegenerative diseases (NDs), Alzheimer's (AD) and Parkinson's (PD) diseases, are characterized by the incidence of proteinopathy, abnormal activation of glial cells, oxidative stress, neuroinflammation, impaired autophagy and cellular senescence excessive for the patient's age. Moreover, mitochondrial disfunction, epigenetic alterations and neurogenesis inhibition, together with increased blood-brain barrier permeability and gut dysbiosis, have been linked to ND pathogenesis. Since NDs still lack curative treatment, recent research has sought therapeutic options in restoring gut microbiota and supplementing probiotic bacteria-derived metabolites with beneficial action to the host-so called postbiotics. The current review focuses on literature explaining cellular mechanisms involved in ND pathogenesis and research addressing the impact that postbiotics as a whole mixture and particular metabolites, such as short-chain fatty acids (SCFAs), lactate, polyamines, polyphenols, tryptophan metabolites, exopolysaccharides and bacterial extracellular vesicles, have on the ageing-associated processes underlying ND occurrence. The review also discusses the issue of implementing postbiotics into ND prophylaxis and therapy, depicting them as compounds addressing senescence-triggered dysfunctions that are worth translating from bench to pharmaceutical market in response to "silver consumers" demands.

Deciphering the Role of miR-30a-5p and DLGAP1 Gene in Non-small Cell Lung Cancer.

BACKGROUND/AIM: Non-small cell lung cancer (NSCLC) is the deadliest form of cancer worldwide. Understanding the mechanisms of lung cancer development is vital for targeted therapy advancements. This article explores the little-known role of the guanylate kinase-associated protein (GKAP), encoded by the Disks large-associated protein 1 (DLGAP1) gene, in NSCLC along with assessing microRNA-30a-5p's influence on DLGAP1 gene expression in the A549 cell line. MATERIALS AND METHODS: Experiments were conducted on A549 cells transfected with synthetic oligonucleotides. The luciferase assay was employed to confirm the binding site of miR-30a-5p to the 3'UTR of DLGAP1 mRNA. The role of miRNA-30a-5p mimic in regulating potential target gene expression at the protein and mRNA levels was studied by performing RT-qPCR and western blot analyses. The effects of DLGAP1 knockdown and miRNA-30a-5p mimic on cell viability and the cell cycle were evaluated using the MTT test and flow cytometry with annexin/iodide cell staining. RESULTS: The luciferase assay indicated that miR-30a-5p has the ability to bind to the 3'UTR of DLGAP1 mRNA. RT-qPCR revealed that the overexpression of miR-30a-5p down-regulates DLGAP1 mRNA. Western blot analysis indicated that miR-30a-5p slightly reduces the level of the GKAP protein. Knockdown of DLGAP1 with synthetic oligonucleotides, as well as transfection with a miR-30a-5p mimic, significantly attenuates cell proliferation and increases the number of cells in the early and late stages of apoptosis. CONCLUSION: Our findings reveal the antiproliferative effect of miR-30a-5p and DLGAP1 gene knockdown on A549 cancer cells, implying that these elements could be considered as therapeutic targets for personalized medicine in NSCLC patients.

Nature's Green Potential: Anticancer Properties of Plants of the Euphorbiaceae Family.

The number of cancer cases will reach 24 million in 2040, according to the International Agency for Research on Cancer. Current treatments for cancer are not effective and selective for most patients; for this reason, new anticancer drugs need to be developed and researched enough. There are potentially useful drugs for cancer isolated from plants that are being used in the clinic. Available information about phytochemistry, traditional uses, in vitro and in vivo experiments with plants, and pure compounds isolated from the Euphorbiaceae family indicates that this family of plants has the potential to develop anticancer drugs. This review examines selected species from the Euphorbiaceae family and their bioactive compounds that could have potential against different types of cancer cells. It reviews the activity of crude extracts, isolated compounds, and nanoparticles and the potential underlying mechanisms of action.
