Abstract
Cancer is among the leading causes of death worldwide. The effectiveness of conventional chemotherapy has some drawbacks, therefore, there is an urgency to develop novel strategies to fight this disease. Ornithine decarboxylase (ODC) is the most finely tuned enzyme of the polyamine (PA) biosynthesis pathway as it is regulated at different levels: transcriptional, translational, post-translational, and by feedback inhibition. In cancer, this enzyme is overexpressed due to its regulation by the protooncogene c-Myc, thus it has been proposed as a drug target against this disease. This review describes information regarding the biochemistry and regulation of the ODC at different levels and its role in cancer. Moreover, we discuss the molecules aiming on the inhibition of the ODC activity that have been tested as therapeutic options. ODC remains as a therapeutic opportunity that needs to be more explored.

Abstract
(1) Background: Photodynamic therapy (PDT) involves the selective killing of tumor cells by the generation of reactive oxygen species using a photosensitizer (PS) activated by irradiation. In melanoma, PDT efficiency is altered by several mechanisms, such as the presence of melanin and melanosomes and pro-survival pathways mediated by transcription factors such as: AP-1 (activator protein), MITF (microphthalmia inducible transcription factor), HIF1α (hypoxia inducible factor), and NF-kB (nuclear factor kappa B). The study aimed to investigate the anti-melanoma effects of PDT mediated by meso-5,10,15,20-tetrakis-(4-hydroxyphenyl)-porphyrin (THPP) as a photosensitizer. (2) Methods: Cocultures of melanoma, two human, WM35 and M1–15, and murine B16-F10, with endothelial cells, were used. Cytotoxicity, oxidative damage, angiogenesis markers, and melanogenesis were assessed using colorimetry, flowcytometry, confocal microscopy, spectrophotometry, ELISA, and Western blotting. (3) Results: The maximal killing efficiency of PDT was reached in WM35, followed by M1–15, and then B16-F10, and it occurred through both apoptosis and necrosis. Although constitutive pigmentation diminished the PDT efficiency, de novo melanogenesis exhibited no protection. PDT increased TNFα, and inhibited NFkB, MITF, HIF1α, and AP1, leading to inflammation and angiogenesis markers’ inhibition. (4) Conclusions: THPP-mediated PDT efficiently induced cell death through apoptosis, necrosis, and the inhibition of pro-survival pathways mediated by NFkB, AP1, HIF1α, and MITF in the melanoma coculture models.

Abstract
Mitochondria, the main provider of energy in eukaryotic cells, contains more than 1000 different proteins and is closely related to the development of cells. However, damaged proteins impair mitochondrial function, further contributing to several human diseases. Evidence shows mitochondrial proteases are critically important for protein maintenance. Most importantly, quality control enzymes exert a crucial role in the modulation of mitochondrial functions by degrading misfolded, aged, or superfluous proteins. Interestingly, cancer cells thrive under stress conditions that damage proteins, so targeting mitochondrial quality control proteases serves as a novel regulator for cancer cells. Not only that, mitochondrial quality control proteases have been shown to affect mitochondrial dynamics by regulating the morphology of optic atrophy 1 (OPA1), which is closely related to the occurrence and progression of cancer. In this review, we introduce mitochondrial quality control proteases as promising targets and related modulators in cancer therapy with a focus on caseinolytic protease P (ClpP), Lon protease (LonP1), high-temperature requirement protein A2 (HrtA2), and OMA-1. Further, we summarize our current knowledge of the advances in clinical trials for modulators of mitochondrial quality control proteases. Overall, the content proposed above serves to suggest directions for the development of novel antitumor drugs.

Abstract
Melanin is a biopolymer reported for diverse biological actions to secure organisms over adverse environmental factors. In the last decade, melanin attributed considerable attention for its use in bioelectronics, photoprotection, environmental bioremediation, and drug discovery. Molecular docking study is the emerging trend in drug discovery for drug designing by targeting proteins. Considering the therapeutic nature of the melanin, we extracted melanin from Streptomyces sp. strain MR28, and it was tested for various biological activities, viz., DPPH free radical scavenging potency, sun protection factor (SPF), drug likeness by SwissADME, molecular docking of melanin on melanocyte-inducing transcription factor (MITF) proteins, cytotoxic activity on A375 malignant melanoma with induction of apoptosis study by flow cytometry, and adsorption study of melanin on doxorubicin and camptothecin drug for drug uptake by melanin. The melanin showed good scavenging potency of DPPH free radicals in a concentration-dependent manner. SPF of 38.64 ± 0.63, 55.53 ± 0.53, and 67.07 ± 0.82 were recorded at 0.06, 0.08, and 0.1 µg/mL, concentrations, respectively. SwissADME screening confirms the drug likeness of melanin. Docking of melanin with MITF proteins exhibited a maximum of - 9.2 kcal/mol binding affinity for 4ATK protein. Cytotoxicity of the melanin drug exhibited good inhibition of melanoma cells in dose-dependent way with significant IC50 of 65.61 µg/mL; apoptotic study reveals melanin showed 64.02% apoptosis for melanin and 33.8% apoptosis for standard drug (doxorubicin). The maximum adsorptions for selected drugs camptothecin and doxorubicin to melanin were recorded at 90 min. In conclusion, the extracted melanin showed significant results over many biological applications and it can be used in the pharmaceutical field to avoid chemical-based drugs.

7,8-Dihydroxyflavone Enhanced Colonic Cholinergic Contraction and Relieved Loperamide-Induced Constipation in Rats. Dig Dis Sci 2021; 66:4251-4262. [PMID: 33528684 DOI: 10.1007/s10620-020-06817-y] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/15/2020] [Accepted: 12/29/2020] [Indexed: 12/14/2022]
Abstract
BACKGROUND Whether 7,8-dihydroxyflavone (7,8-DHF), a tyrosine kinase receptor B (TrkB) agonist, modulates colonic smooth muscle motility and/or alleviates constipation has not yet been studied. AIMS Here, we aimed to determine how 7,8-DHF influences carbachol (CCh)-stimulated contraction of colonic strips and the in vivo effect of 7,8-DHF on constipation. METHODS Muscle strips were isolated from rat colons for recording contractile tension and performing western blotting. Constipation was induced in rats with loperamide. RESULTS Although it specifically activated TrkB, 7,8-DHF applied alone neither activated PLCγ1 in the colonic strips nor induced colonic strip contraction. However, 7,8-DHF enhanced CCh-stimulated PLCγ1 activation and strip contraction. The PLCγ1 antagonist U73122 suppressed both CCh-stimulated and 7,8-DHF-enhanced/CCh-stimulated contraction. While clarifying the underlying mechanism, we revealed that 7,8-DHF augmented muscarinic M3 receptor expression in the colonic strips. The M3-selective antagonist tarafenacin specifically inhibited the 7,8-DHF-enhanced/CCh-stimulated contraction of the colonic strips. Since 7,8-DHF increased Akt phosphorylation, and LY294002 (an antagonist of PI3K upstream of Akt) dramatically inhibited both 7,8-DHF-augmented M3 expression and 7,8-DHF-enhanced/CCh-stimulated contractions, we assumed that 7,8-DHF/TrkB/Akt was associated with the modulation of M3 expression in the colonic strips. ANA-12, a specific TrkB antagonist, not only inhibited TrkB activation by 7,8-DHF but also suppressed 7,8-DHF-enhanced cholinergic contraction, 7,8-DHF/CCh-mediated activation of PLCγ1/Akt, and M3 overexpression in colonic strips. In vivo 7,8-DHF, also by promoting intestinal motility and M3 expression, significantly alleviated loperamide-induced functional constipation in rats. CONCLUSIONS Our results suggest that 7,8-DHF regulates colonic motility possibly via a TrkB/Akt/M3 pathway and may be applicable for alleviating constipation.

Abstract
Recent studies suggest that 7,8-dihydroxyflavone (7,8-DHF) inhibits the development of several tumors. However, its role in osteosarcoma (OS) remains unknown. This study was designed to investigate the effects and underlying mechanisms of 7,8-DHF that may influence OS development. Human OS cell lines (U2OS and 143B) were treated with 7,8-DHF; cell viability and cell migration were assessed by methylthiazolyldiphenyl-tetrazolium bromide (MTT) assay and wound-healing assay, respectively; and cell death and apoptosis were evaluated by LIVE/DEAD staining and terminal deoxynucleotidyl transferase (TdT) dUTP nick-end labeling (TUNEL) assay, respectively. Reactive oxygen species production was measured using 2,7-dichlorodihydrofluorescein diacetate probe. Akt, Bcl-xL/Bcl-2 asociated death promoter (Bad), p38 mitogen-activated protein kinase (MAPK), extracellular regulated protein kinase (ERK), and c-Jun N-terminal kinase (JNK) expression and their respective phosphorylation levels were detected by western blot analysis. We found that 7,8-DHF reduced cell viability in a dose-dependent manner and also promoted apoptosis, inhibited migration, and induced oxidative stress in OS cells. Moreover, 7,8-DHF inhibited Akt, Bad, and p38MAPK, but activated ERK and JNK signals. In summary, our results suggest that 7,8-DHF inhibits OS progression, possibly by regulating Akt/Bad and MAPK signaling. These findings provide new evidence for the pharmacological effects of 7,8-DHF that may improve drug therapy for OS patients.

7,8-Dihydroxyflavone protects retinal ganglion cells against chronic intermittent hypoxia-induced oxidative stress damage via activation of the BDNF/TrkB signaling pathway. Sleep Breath 2021; 26:287-295. [PMID: 33993395 DOI: 10.1007/s11325-021-02400-5] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2020] [Revised: 02/26/2021] [Accepted: 05/05/2021] [Indexed: 10/21/2022]
Abstract
PURPOSE Chronic intermittent hypoxia (CIH) plays a key role in the complications of obstructive sleep apnea (OSA), which is strongly associated with retinal and optic nerve diseases. Additionally, the brain-derived neurotrophic factor (BDNF)/tropomyosin receptor kinase B (TrkB) signaling pathway plays an important protective role in neuronal injury. In the present study, we investigated the role of 7,8-dihydroxyflavone (7,8-DHF) in regulating CIH-induced injury in mice retinas and rat primary retinal ganglion cells (RGCs). METHODS C57BL/6 mice and in vitro primary RGCs were exposed to CIH or normoxia and treated with or without 7,8-DHF. The mice eyeballs or cultured cells were then taken for histochemistry, immunofluorescence or biochemistry, and the protein expression of the BDNF/TrkB signaling pathway analysis. RESULTS Our results showed that CIH induced oxidative stress (OS) in in vivo and in vitro models and inhibited the conversion of BDNF precursor (pro-BDNF) to a mature form of BDNF, which increased neuronal cell apoptosis. 7,8-DHF reduced the production of reactive oxygen species (ROS) caused by CIH and effectively activated TrkB signals and downstream protein kinase B (Akt) and extracellular signal-regulated kinase (Erk) survival signaling pathways, which upregulated the expression of mature BDNF. ANA-12 (a TrkB specific inhibitor) blocked the protective effect of 7,8-DHF. CONCLUSION In short, the activation of the BDNF/TrkB signaling pathway alleviated CIH-induced oxidative stress damage of the optic nerve and retinal ganglion cells. 7,8-DHF may serve as a promising agent for OSA related neuropathy.

Abstract
Cutaneous malignant melanoma is a heterogeneous disease, being the consequence of specific genetic alterations along several molecular pathways. Despite the increased knowledge about the biology and pathogenesis of melanoma, the incidence has grown markedly worldwide, making it extremely important to develop preventive measures. The beneficial role of correct nutrition and of some natural dietary compounds in preventing malignant melanoma has been widely demonstrated. This led to numerous studies investigating the role of several dietary attitudes, patterns, and supplements in the prevention of melanoma, and ongoing research investigates their impact in the clinical management and outcomes of patients diagnosed with the disease. This article is an overview of recent scientific advances regarding specific dietary compounds and their impact on melanoma development and treatment.

Abstract
Malignant melanoma is the deadliest form of skin cancer and highly chemoresistant. Melittin, an amphiphilic peptide containing 26 amino acid residues, is the major active ingredient from bee venom (BV). Although melittin is known to have several biological activities such as anti-inflammatory, antibacterial and anticancer effects, its antimelanoma effect and underlying molecular mechanism have not been fully elucidated. In the current study, we investigated the inhibitory effect and action mechanism of BV and melittin against various melanoma cells including B16F10, A375SM and SK-MEL-28. BV and melittin potently suppressed the growth, clonogenic survival, migration and invasion of melanoma cells. They also reduced the melanin formation in α-melanocyte-stimulating hormone (MSH)-stimulated melanoma cells. Furthermore, BV and melittin induced the apoptosis of melanoma cells by enhancing the activities of caspase-3 and -9. In addition, we demonstrated that the antimelanoma effect of BV and melittin is associated with the downregulation of PI3K/AKT/mTOR and MAPK signaling pathways. We also found that the combination of melittin with the chemotherapeutic agent temozolomide (TMZ) significantly increases the inhibition of growth as well as invasion in melanoma cells compared to melittin or TMZ alone. Taken together, these results suggest that melittin could be potentially applied for the prevention and treatment of malignant melanoma.

Most Nocardia spp. have metabolic ability to produce compounds of diverse nature, so one-strain-many-compounds (OSMAC) approach can be applied for obtaining versatile compounds from these strains. In this study, we characterized a novel 1, 3, 6, 8-tetrahydroxynaphthalene (THN) derivative by metabolic engineering approach leading to the inactivation of nargenicin A1 biosynthesis. By using genome mining, metabolite profiling, and bioinformatics, the biosynthetic gene cluster and biosynthetic mechanism were elucidated. Further, the antibacterial, anticancer, melanin formation, and UV protective properties for isolated THN compound were performed. The compound did not exhibit significant antibacterial and cytotoxic activities, but it exhibited promising UV protection effects. Thus, metabolic engineering is an effective strategy for discovering novel bioactive molecules.
