Mitochondrial mutations and mitoepigenetics: Focus on regulation of oxidative stress-induced responses in breast cancers.

Epigenetic regulation of mitochondrial DNA (mtDNA) is an emerging and fast-developing field of research. Compared to regulation of nucler DNA, mechanisms of mtDNA epigenetic regulation (mitoepigenetics) remain less investigated. However, mitochondrial signaling directs various vital intracellular processes including aerobic respiration, apoptosis, cell proliferation and survival, nucleic acid synthesis, and oxidative stress. The later process and associated mismanagement of reactive oxygen species (ROS) cascade were associated with cancer progression. It has been demonstrated that cancer cells contain ROS/oxidative stress-mediated defects in mtDNA repair system and mitochondrial nucleoid protection. Furthermore, mtDNA is vulnerable to damage caused by somatic mutations, resulting in the dysfunction of the mitochondrial respiratory chain and energy production, which fosters further generation of ROS and promotes oncogenicity. Mitochondrial proteins are encoded by the collective mitochondrial genome that comprises both nuclear and mitochondrial genomes coupled by crosstalk. Recent reports determined the defects in the collective mitochondrial genome that are conducive to breast cancer initiation and progression. Mutational damage to mtDNA, as well as its overproliferation and deletions, were reported to alter the nuclear epigenetic landscape. Unbalanced mitoepigenetics and adverse regulation of oxidative phosphorylation (OXPHOS) can efficiently facilitate cancer cell survival. Accordingly, several mitochondria-targeting therapeutic agents (biguanides, OXPHOS inhibitors, vitamin-E analogues, and antibiotic bedaquiline) were suggested for future clinical trials in breast cancer patients. However, crosstalk mechanisms between altered mitoepigenetics and cancer-associated mtDNA mutations remain largely unclear. Hence, mtDNA mutations and epigenetic modifications could be considered as potential molecular markers for early diagnosis and targeted therapy of breast cancer. This review discusses the role of mitoepigenetic regulation in cancer cells and potential employment of mtDNA modifications as novel anti-cancer targets.

Implications of nanotechnology for the treatment of cancer: Recent advances.

The use of nanoparticles dramatically increases the safety and efficacy of the most common anticancer drugs. The main advantages of nano-drugs and delivery systems based on nano-technology are effective targeting, delayed release, increased half-life, and less systemic toxicity. The use of nano-carriers has led to significant improvements in drug delivery to targets compared with traditional administration of these drugs. In this review, the main tendencies in nano-drug formulations as well as factors limiting their use in clinical settings are discussed. Additionally, the current status of approved nano-drugs for cancer treatment is reviewed.

Extracellular vesicles in cancer nanomedicine.

To date, a lot of nanotechnological optitions are available for targeted drug delivery. Extracellular vesicles (EVs) are membrane structures that cells use for storage, transport, communication, and signaling. Recent research has focused on EVs as natural nanoparticles for drug delivery. This review sheds light on the application of EVs in cancer therapy, such as targeted chemotherapy, gene therapy, and vaccine development. Aspects of biogenesis, isolation, targeting, and loading of EVs are discussed in detail.

Dysbiosis is one of the risk factor for stroke and cognitive impairment and potential target for treatment.

More than 50 million people have various forms of cognitive impairment basically caused by neurodegenerative diseases, such as Alzheimer's, Parkinson's, and cerebrovascular diseases as well as stroke. Often these conditions coexist and exacerbate one another. The damaged area in post-stroke dementia may lead to neurodegenerative lesions. Gut microbiome functions like an endocrine organ by generating bioactive metabolites that can directly or indirectly impact human physiology. An alteration in the composition and function of intestinal flora, i.e. gut dysbiosis, is implicated in neurodegenerative and cerebrovascular diseases. Additionally, gut dysbiosis may accelerate the progression of cognitive impairment. Dysbiosis may result from obesity; metabolic disorders, cardiovascular disease, and sleep disorders, Lack of physical activity is associated with dysbiosis as well. These may coexist in various patterns in older people, enhancing the risk, incidence, and progression of cerebrovascular lesions, neurodegenerative disorders, and cognitive impairment, creating a vicious circle. Recently, it has been reported that several metabolites produced by gut microbiota (e.g., trimethylamine/trimethylamine N-oxide, short-chain fatty acids, secondary bile acids) may be linked to neurodegenerative and cerebrovascular diseases. New treatment modalities, including prebiotic and probiotics, may normalize the gut microbiota composition, change the brain-gut barrier, and decrease the risk of the pathology development. Fecal microbiota transplantation, sometimes in combination with other methods, is used for remodeling and replenishing the symbiotic gut microbiome. This promising field of research is associated with basic findings of bidirectional communication between body organs and gut microbiota that creates new possibilities of pharmacological treatments of many clinical conditions. The authors present the role of gut microbiota in physiology, and the novel therapeutic targets in modulation of intestinal microbiota Personalized therapies based on their personal genome make up could offer benefits by modulating microbiota cross-talk with brain and cardiovascular system. A healthy lifestyle, including pre and probiotic nutrition is generally recommended. Prevention may also be enhanced by correcting gut dysbiosis resulting a reduced risk of post-stroke cognitive impairment including dementia.

The Association of Sleep Disorders, Obesity and Sleep-Related Hypoxia with Cancer.

BACKGROUND: Sleep disorders have emerged as potential cancer risk factors. OBJECTIVE: This review discusses the relationships between sleep, obesity, and breathing disorders with concomitant risks of developing cancer. RESULTS: Sleep disorders result in abnormal expression of clock genes, decreased immunity, and melatonin release disruption. Therefore, these disorders may contribute to cancer development. Moreover, in sleep breathing disorder, which is frequently experienced by obese persons, the sufferer experiences intermittent hypoxia that may stimulate cancer cell proliferation. DISCUSSION: During short- or long- duration sleep, sleep-wake rhythm disruption may occur. Insomnia and obstructive sleep apnea increase cancer risks. In short sleepers, an increased risk of stomach cancer, esophageal squamous cell cancer, and breast cancer was observed. Among long sleepers (>9 hours), the risk of some hematologic malignancies is elevated. CONCLUSION: Several factors including insomnia, circadian disruption, obesity, and intermittent hypoxia in obstructive sleep apnea are contributing risk factors for increased risk of several types of cancers. However, further studies are needed to determine the more significant of these risk factors and their interactions.

The Long-Term Effect of Medically Enhancing Melanin Intrinsic Bioenergetics Capacity in Prematurity.

BACKGROUND: The ability of the human body to produce metabolic energy from light modifies fundamental concepts of biochemistry. OBJECTIVE: This review discusses the relationships between the long-accepted concept is that glucose has a unique dual role as an energy source and as the main source of carbon chains that are precursors of all organic matter. The capability of melanin to produce energy challenges this premise. METHODS: The prevalent biochemical concept, therefore, needs to be adjusted to incorporate a newly discovered state of Nature based on melanin's ability to dissociate water to produce energy and to re-form water from molecular hydrogen and oxygen. RESULTS AND DISCUSSION: Our findings regarding the potential implication of QIAPI-1 as a melanin precursor that has bioenergetics capabilities. CONCLUSION: Specifically, we reported its promising application as a means for treating retinopathy of prematurity (ROP). The instant report focuses on the long-term treatment medical effects of melanin in treating ROP.

Extensive tracheal resection in lung cancer and tuberculosis: a case report.

BACKGROUND: Tracheal bifurcation resection remains the greatest challenge in airway reconstruction, especially with extensive lesions. Additionally, lung cancer and pulmonary tuberculosis comorbidity complicate the chemoradiotherapy treatment due to the TB reactivation. This case describes tracheal resection in a patient with both tuberculosis (TB) and lung cancer. CASE PRESENTATION: The patient was diagnosed with right lung tuberculosis and upper lobe cancer with trachea invasion complicated by hemoptysis. A right pneumonectomy with circular trachea bifurcation resection was performed. Radiotherapy and chemotherapy were not administered to avoid TB reactivation. At 5.5 years post-surgery, there was cancer recurrence that was treated with radiation therapy. At 10 years post-surgery, an invasive squamous-cell carcinoma of a three-segment bronchus on the left was revealed. Radiation therapy and a course of chemotherapy were carried out with almost complete tumor regression. CONCLUSIONS: TB presence should not serve as a basis for the refusal of cancer treatment. Combined treatment may be recommended when the main infection focus in the pulmonary parenchyma is removed during surgery.

Updated Understanding of Cancer as a Metabolic and Telomere-Driven Disease, and Proposal for Complex Personalized Treatment, a Hypothesis.

In this review, we propose a holistic approach to understanding cancer as a metabolic disease. Our search for relevant studies in medical databases concludes that cancer cells do not evolve directly from normal healthy cells. We hypothesize that aberrant DNA damage accumulates over time-avoiding the natural DNA controls that otherwise repair or replace the rapidly replicating cells. DNA damage starts to accumulate in non-replicating cells, leading to senescence and aging. DNA damage is linked with genetic and epigenetic factors, but the development of cancer is favored by telomerase activity. Evidence indicates that telomere length is affected by chronic inflammations, alterations of mitochondrial DNA, and various environmental factors. Emotional stress also influences telomere length. Chronic inflammation can cause oxidative DNA damage. Oxidative stress, in turn, can trigger mitochondrial changes, which ultimately alter nuclear gene expression. This vicious cycle has led several scientists to view cancer as a metabolic disease. We have proposed complex personalized treatments that seek to correct multiple changes simultaneously using a psychological approach to reduce chronic stress, immune checkpoint therapy with reduced doses of chemo and radiotherapy, minimal surgical intervention, if any, and mitochondrial metabolic reprogramming protocols supplemented by intermittent fasting and personalized dietary plans without interfering with the other therapies.

Can miRNAs Be Considered as Diagnostic and Therapeutic Molecules in Ischemic Stroke Pathogenesis?-Current Status.

Ischemic stroke is one of the leading causes of death worldwide. Clinical manifestations of stroke are long-lasting and causing economic burden on the patients and society. Current therapeutic modalities to treat ischemic stroke (IS) are unsatisfactory due to the intricate pathophysiology and poor functional recovery of brain cellular compartment. MicroRNAs (miRNA) are endogenously expressed small non-coding RNA molecules, which can act as translation inhibitors and play a pivotal role in the pathophysiology associated with IS. Moreover, miRNAs may be used as potential diagnostic and therapeutic tools in clinical practice; yet, the complete role of miRNAs is enigmatic during IS. In this review, we explored the role of miRNAs in the regulation of stroke risk factors viz., arterial hypertension, metabolic disorders, and atherosclerosis. Furthermore, the role of miRNAs were reviewed during IS pathogenesis accompanied by excitotoxicity, oxidative stress, inflammation, apoptosis, angiogenesis, neurogenesis, and Alzheimer's disease. The functional role of miRNAs is a double-edged sword effect in cerebral ischemia as they could modulate pathological mechanisms associated with risk factors of IS. miRNAs pertaining to IS pathogenesis could be potential biomarkers for stroke; they could help researchers to identify a particular stroke type and enable medical professionals to evaluate the severity of brain injury. Thus, ascertaining the role of miRNAs may be useful in deciphering their diagnostic role consequently it is plausible to envisage a suitable therapeutic modality against IS.

The Modulation of Adipokines, Adipomyokines, and Sleep Disorders on Carcinogenesis.

Obesity and sarcopenia, i.e., decreased skeletal muscle mass and function, are global health challenges. Moreover, people with obesity and sedentary lifestyles often have sleep disorders. Despite the potential associations, metabolic disturbances linking obesity, sarcopenia, and sleep disorders with cancer are neither well-defined nor understood fully. Abnormal levels of adipokines and adipomyokines originating from both adipose tissue and skeletal muscles are observed in some patients with obesity, sarcopenia and sleep disorders, as well as in cancer patients. This warrants investigation with respect to carcinogenesis. Adipokines and adipomyokines may exert either pro-carcinogenic or anti-carcinogenic effects. These factors, acting independently or together, may significantly modulate the incidence and progression of cancer. This review indicates that one of the possible pathways influencing the development of cancer may be the mutual relationship between obesity and/or sarcopenia, sleep quantity and quality, and adipokines/adipomyokines excretion. Taking into account the high proportion of persons with obesity and sedentary lifestyles, as well as the associations of these conditions with sleep disturbances, more attention should be paid to the individual and combined effects on cancer pathophysiology.

Neurokinin-1 Receptor Antagonist Reverses Functional CNS Alteration Caused by Combined γ-rays and Carbon Nuclei Irradiation.

BACKGROUND: Ionizing Radiation (IR) is one of the major limiting factors for human deep-space missions. Preventing IR-induced cognitive alterations in astronauts is a critical success factor. It has been shown that cognitive alterations in rodents can be inferred by alterations of a psycho- emotional balance, primarily an anxiogenic effect of IR. In our recent work, we hypothesized that the neurokinin-1 (NK1) receptor might be instrumental for such alterations. OBJECTIVE: The NK1 receptor antagonist rolapitant and the classic anxiolytic diazepam (as a comparison drug) were selected to test this hypothesis on Wistar rats. METHODS: Pharmacological substances were administered through intragastric probes. We used a battery of tests for a comprehensive ethological analysis. High-performance liquid chromatography was applied to quantify monoamines content. An analysis of mRNA expression was performed by real-time PCR. Protein content was studied by the Western blotting technique. RESULTS: Our salient finding includes no substantial changes in anxiety, locomotor activity and cognitive abilities of treated rats under irradiation. No differences were found in the content of monoamines. We discovered a synchronous effect on mRNA expression and protein content of 5- HT2a and 5-HT4 receptors in the prefrontal cortex, as well as decreased content of serotonin transporter and increased content of tryptophan hydroxylase in the hypothalamus of irradiated rats. Rolapitant affected the protein amount of a number of serotonin receptors in the amygdala of irradiated rats. CONCLUSION: Rolapitant may be the first atypical radioprotector, providing symptomatic treatment of CNS functional disorders in astronauts caused by IR.

The Role of Stem Cells in the Therapy of Stroke.

BACKGROUND: Stroke is a major challenge in neurology due to its multifactorial genesis and irreversible consequences. Processes of endogenous post-stroke neurogenesis, although insufficient, may indicate possible direction of future therapy. Multiple research considers stem-cell-based approaches in order to maximize neuroregeneration and minimize post-stroke deficits. OBJECTIVE: Aim of this study is to review current literature considering post-stroke stem-cell- based therapy and possibilities of inducing neuroregeneration after brain vascular damage. METHODS: Papers included in this article were obtained from PubMed and MEDLINE databases. The following medical subject headings (MeSH) were used: "stem cell therapy", "post-stroke neurogenesis", "stem-cells stroke", "stroke neurogenesis", "stroke stem cells", "stroke", "cell therapy", "neuroregeneration", "neurogenesis", "stem-cell human", "cell therapy in human". Ultimate inclusion was made after manual review of the obtained reference list. RESULTS: Attempts of stimulating neuroregeneration after stroke found in current literature include supporting endogenous neurogenesis, different routes of exogenous stem cells supplying and extracellular vesicles used as a method of particle transport. CONCLUSION: Although further research in this field is required, post stroke brain recovery supported by exogenous stem cells seems to be promising future therapy revolutionizing modern neurology.

The Beneficial Effects of QIAPI 1® against Pentavalent Arsenic-Induced Lung Toxicity: A Hypothetical Model for SARS CoV2-I nduced Lung Toxicity.

Exposure to environmental toxicants such as Arsenic (As) can result in As-induced alterations in immune regulators. Consequently, people who are more prone to viral infections like influenza A or B, H1N1, SARS CoV (Severe Acute Respiratory Syndrome Coronavirus), and SARS CoV2 may develop a susceptibility to immune responses in their lungs because our previous reports delineated the ability of QIAPI 1®, a melanin precursor, to dissociate water molecules with simultaneous therapeutic efficacy against central nervous system (CNS) diseases, retinopathy, and As-induced renal toxicity. Considering the commonalitie of lung pathology of SARS CoV and As-induced toxicity, the aim of this study is to decipher the efficacy of QIAPI 1® against pentavalent As-induced lung toxicity by examining the pulmonary pathology. Hematoxylin & Eosin (H&E) staining was used for ascertaining the lung pathology in Wistar rat models. Animals were divided into 3 groups: control group, group treated with pentavalent As, and a group treated with pentavalent As and QIAPI 1®. There were no significant changes in lung histopathology in the control group as indicated by intact morphology. The As-treated group revealed damage to the histoarchitecture with pulmonary edema, interstitial fibrosis, diffuse alveolar damage, Bronchiolitis obliterans organizing pneumonia (BOOP)-lesions, formation of hyaline membrane, multinucleated giant pneumocytes, atypical pneumocytes, inflammatory cell infiltration, and interstitial edema. The group treated with As and QIAPI 1® significantly associated with mitigated histological signs of lung inflammation induced by Arsenic. Therefore, QIAPI 1® can be recommended as antagonistic to Asinduced lung toxicity. In conclusion, this model could be preferred as a hypothetical model to examine the efficacy of QIAPI 1® in SARS CoV2-induced pulmonary damage. Future studies are warranted to delineate the efficacy of QIAPI 1® against SARS CoV and SARS CoV2 lung pathology.

The Dawn of Mitophagy: What Do We Know by Now?

Mitochondria are essential organelles for healthy eukaryotic cells. They produce energyrich phosphate bond molecules (ATP) through oxidative phosphorylation using ionic gradients. The presence of mitophagy pathways in healthy cells enhances cell protection during mitochondrial damage. The PTEN-induced putative kinase 1 (PINK1)/Parkin-dependent pathway is the most studied for mitophage. In addition, there are other mechanisms leading to mitophagy (FKBP8, NIX, BNIP3, FUNDC1, BCL2L13). Each of these provides tethering of a mitochondrion to an autophagy apparatus via the interaction between receptor proteins (Optineurin, p62, NDP52, NBR1) or the proteins of the outer mitochondrial membrane with ATG9-like proteins (LC3A, LC3B, GABARAP, GABARAPL1, GATE16). Another pathogenesis of mitochondrial damage is mitochondrial depolarization. Reactive oxygen species (ROS) antioxidant responsive elements (AREs) along with antioxidant genes, including pro-autophagic genes, are all involved in mitochondrial depolarization. On the other hand, mammalian Target of Rapamycin Complex 1 (mTORC1) and AMP-dependent kinase (AMPK) are the major regulatory factors modulating mitophagy at the post-translational level. Protein-protein interactions are involved in controlling other mitophagy processes. The objective of the present review is to analyze research findings regarding the main pathways of mitophagy induction, recruitment of the autophagy machinery, and their regulations at the levels of transcription, post-translational modification and protein-protein interaction that appeared to be the main target during the development and maturation of neurodegenerative disorders.

The Role of Neurogenic Bioamines in Nerve Fibers of Uterus during the Postpartum Involution in Experimental Animal Models.

BACKGROUND: Biogenic amines (BAs) secreted by the sympathetic neural apparatus of rat uterus are reported to be conducive to the uterine functional activity during postpartum involution; the imbalance in BAs ratio could confer postpartum reproductive disorders including improper postpartum involution. OBJECTIVE: The objective of this study is to identify the changes in the density of uterine sympathetic nerves implicated in the pathology of endometriosis, adenomyosis, and delayed uterine involution. The present study aims to ascertain 'serotonin' and 'catecholamine' concentrations in mesenteric mast cells (MCs), and structural elements of nerve fibers across the perivascular plexuses (PPs) and single sympathetic nerve terminals (SST). METHODS: Furthermore, the density of their spatial distribution (SDP and SDT) in the uterine body, cervix, and mesometrium was determined during postpartum involution. Tissue specimens of postpartum uterus were obtained from 55 nulliparous female Wistar outbred strain rats, which were grouped according to the days after parturition at the time of sacrifice. The nerve fibers of PP and SST exhibited emerald green fluorescence, which was detected by glyoxylic acid fluorescence technique; the fluorescence invoked by BAs was identified by microspectrofluorimetry. RESULTS: Concentrations of BAs were extensive in the varicosities of PP and SST on the 10th day. However, the highest BA concentrations were found in structural elements of PP in the uterine mesometrium in the initial days of postpartum. In mesenteric MC, serotonin and catecholamines were at the highest concentration on the 10th day of postpartum. Histamines peaked on the 6th day. CONCLUSION: SDP and SDT were increased significantly in all structural elements of uterine nerve fibers in the uterine body and cervix compared to SDP in mesentery. Considering that catecholamines and serotonin are antagonists in many aspects of their biological action, the ratio of BAs should be well-balanced to maintain anabolic- catabolic equilibrium in the rat uterus.

Hypothetical Role of Growth Factors to Reduce Intervertebral Disc Degeneration Significantly through Trained Biological Transformations.

BACKGROUND: Given the evidence of little or no therapeutic benefit of injection-based growth factor therapies, it has been proposed that a naturally triggered uninterrupted blood circulation of the growth factors would be superior. OBJECTIVE: We seek to stimulate discussions and more research about the possibility of using the already available growth factors found in the prostate gland and endometrium by starting novel educable physiology, known as biological transformations controlled by the mind. METHODS: We summarized the stretch-gated ion channel mechanism of the cell membrane and offer several practical methods that can be applied by anyone, in order to stimulate and enhance the blood circulation of the growth factors from the seminal fluid to sites throughout the body. This study describes, in detail, the practical application of our earlier published studies about biological transformations. RESULTS: A previously reported single-patient case study has been extended, adding more from his personal experiences to continually improve this novel physiological training and extending the ideas from our earlier findings in detail. CONCLUSION: The biological transformation findings demonstrate the need for additional research to establish the benefits of these natural therapies to repair and rejuvenate tissues affected by various chronic diseases or aging processes.

Statistical Review of the Suicide Attempts Rates Committed on Polish Railway Tracks between the years 2013-2016.

Suicides on railway tracks are one of the most drastic ones. No research concerning this phenomenon has been done to this date in Poland. This article focuses on the connection between suicidal behaviors on Polish railway tracks and sociodemographic traits and presents risk factors. BACKGROUND: The suicide behavior is largely spread among many European countries. Of these, Poland ranks 22nd in terms of suicide attempts. This study aims to highlight the suicide attempts rates on Polish railways lines and their main risk factors. LIMITATIONS: Limited number of available statistical data before 2013. METHOD: Statistical review of the available Central Police headquarters database and analyses of the influence of the risk factors on people's awareness during the suicide attempts and their geographical distribution in Poland during the years 2013 - 2016. The prevalence of railway suicides in individual voivodeships (provinces) in Poland have been indicated in a 3D map. RESULTS: There were 834 cases of railway suicide fatalities across the entire country. Of the total suicide statistics by any means, 3.75% are railway related. The average known age of those committing railway suicides were: 37.9 years for men (n = 627) and 34.6 for women (n = 155). In most cases, suicides were committed by bachelors (54.3%). The largest group of people who committed suicide had a primary level of education (42.0%). Among the suicides, a significant group are unemployed (45.2%). Alcohol intoxication have been established as responsible for a person's lower awareness of his actions in 70.9% of cases. Almost 63.3% of people had a higher propensity for suicidal ideation and behavior, resulting in their being treated for mental health issues. CONCLUSION: Alcohol intoxication, illegal narcotics and psychotropic medication are responsible for a person's lower awareness during his ore her actions, in most of the cases of suicide on Polish railway lines.
