Investigation of Pancreatic-beta cells Role in the Biological Process of Ageing
CONCLUSION: Aging accelerates beta cell senescence by generating premature cell senescence, which is mostly mediated by high glucose levels. Despite higher plasma glucose levels, hepatic gluconeogenesis accelerates and adipose tissue lipolysis rises, resulting in an increase in free fatty acid levels in the blood and worsening insulin resistance throughout the body.PMID:37608675 | DOI:10.2174/1871530323666230822095932

Structural Insight on GPR119 Agonist as Potential Therapy for Type II Diabetes: A Comprehensive Review
Mini Rev Med Chem. 2023 Mar 2. doi: 10.2174/1389557523666230302140658. Online ahead of print.ABSTRACTDiabetes Mellitus [DM] is a long-term metabolic condition that is characterized by excessive blood glucose. DM is the third most death-causing disease, leading to retinopathy, nephropathy, loss of vision, stroke, and cardiac arrest. Around 90% of the total cases of diabetic patients have Type II Diabetes Mellitus[T2DM]. Among various approaches for the treatment of T2DM. G protein-coupled receptors [GPCRs] 119 have been identified as a new pharmacological target. GPR119 is distributed preferentially in the pancreas β-cells...

Sex Difference of Radiation Response in Occupational and Accidental Exposure
Conclusion and Outlook This review summarizes the data from major human studies on the health risks of radiation exposure and shows that sex can potentially influence the prolonged response to radiation exposure (Figure 1 and Tables 1, 2). These data suggest that long-term radiosensitivity in females is higher than that in males who receive a comparable dose of radiation. Our analysis of the literature agrees with the conclusions of the recent report on the Biological effects of ionizing radiation (BEIR VII) published in 2006 by the National Academy of Sciences (NAS), United States (National Research Council, 2006). The B...

NAMPT as a Dedifferentiation-Inducer Gene: NAD+ as Core Axis for Glioma Cancer Stem-Like Cells Maintenance
Conclusion and Perspectives Gliomas are the most prevalent primary brain cancer in adults and include a broad category of tumors including astrocytoma, oligodendroglioma, and GBM. Regardless of tumor aggressiveness, malignancy, and infiltration, these glia-derived tumors rarely exceed a median survival time of 12–14 months. Driven by the infiltrative nature of these tumors, the clinical approach is difficult and relapses often occur with fatal consequences. These unsuccessful attempts to control glioma's fate have fostered research looking for more effective therapies. (GSCs) are a small subset of CD133&#...

Connecting Metainflammation and Neuroinflammation Through the PTN-MK-RPTP β/ζ Axis: Relevance in Therapeutic Development
Conclusion The expression of the components of the PTN-MK-RPTPβ/ζ axis in immune cells and in inflammatory diseases suggests important roles for this axis in inflammation. Pleiotrophin has been recently identified as a limiting factor of metainflammation, a chronic pathological state that contributes to neuroinflammation and neurodegeneration. Pleiotrophin also seems to potentiate acute neuroinflammation independently of the inflammatory stimulus while MK seems to play different -even opposite- roles in acute neuroinflammation depending on the stimulus. Which are the functions of MK and PTN in chronic neuroi...

Nrf2 as a Potential Mediator of Cardiovascular Risk in Metabolic Diseases
Conclusion Activation of the Nrf2-dependent antioxidant system plays an important role in cell defense against oxidative stress damage, whereas the insufficiency of the Nrf2 system is associated with multiple aspects of the genesis and progression of metabolic diseases, posing a great risk to the cardiovascular system (Figure 1). The systemic increase of Nrf2 activity by several activators may be beneficial in the treatment of metabolic diseases. In addition, selective upregulation of Nrf2 genes may represent a potential therapy in obesity, diabetes and atherosclerosis. Looking to the future, experimental research that el...

Role of TREK-1 in Health and Disease, Focus on the Central Nervous System
Conclusion and Perspectives Since their cloning 20 years ago, the physiological importance of TREK-1 channels has continued to grow (Figure 3). Today, TREK-1 channels have been shown to be important and their presence is essential in a number of physiopathological processes. Their involvement in these different processes demonstrate the necessity to design pharmacological modulators, activators or inhibitors, of these channels to correct any TREK-1-related dysfunctions. Despites a number of studies and many molecule screenings, only few putative new drugs were identified. The activators belonging to the ML and BL series ...

6-Bromoindirubin-3 ′-Oxime (6BIO) Suppresses the mTOR Pathway, Promotes Autophagy, and Exerts Anti-aging Effects in Rodent Liver
In this study, we aimed to investigate the anti-aging effect, and molecular mechanism, of the novel anti-aging drug 6BIO on naturally aged mouse liver. Rapamycin, a well-known promising anti-aging drug that delays aging through mTOR-dependent autophagy (Zhou and Ye, 2018), was used as the positive control in the study. To our knowledge, this is the first study to demonstrate the effects of 6BIO treatment in models of natural aging. Our results indicated that 6BIO ameliorates the decline of liver function with age, including lipid metabolism disorder, and attenuates hepatocyte senescence in aged mice, as revealed by altera...

Molecules, Vol. 23, Pages 258: Action of Phytochemicals on Insulin Signaling Pathways Accelerating Glucose Transporter (GLUT4) Protein Translocation
ury Hossain Diabetes is associated with obesity, generally accompanied by a chronic state of oxidative stress and redox imbalances which are implicated in the progression of micro- and macro-complications like heart disease, stroke, dementia, cancer, kidney failure and blindness. All these complications rise primarily due to consistent high blood glucose levels. Insulin and glucagon help to maintain the homeostasis of glucose and lipids through signaling cascades. Pancreatic hormones stimulate translocation of the glucose transporter isoform 4 (GLUT4) from an intracellular location to the cell surface and facilitate th...

MicroRNAs Mediated MMP Regulation: Current Diagnostic and Therapeutic Strategies for Metabolic Syndrome.
Abstract Metabolic syndrome (MS) is a global socioeconomic problem rapidly progressing in accordance with increasing body mass index (BMI) and age. It is a consortium of risk factors, such as dyslipidaemia, insulin resistance, leptin resistance, reduced adiponectin, glucose intolerance, hyperglycemia, and hypertension. Collectively, these factors accelerate the onset of type 2 diabetes mellitus, cardiovascular disease, stroke, and certain cancers such as breast, liver pancreatic, and colon cancer. Extracellular matrix (ECM) and basement membrane remodeling play a central role during pathogenesis of MS as they regu...

Identifying and Describing the Impact of Cyclone, Storm and Flood Related Disasters on Treatment Management, Care and Exacerbations of Non-communicable Diseases and the Implications for Public Health
Conclusion Cyclone, flood and storm related disasters impact on treatment management and overall care for people with NCDs. This results in an increased risk of exacerbation of illness or even death. The interruption may be caused by a range of factors, such as damaged transport routes, reduced health services, loss of power and evacuations. The health impact varies according to the NCD. For people with chronic respiratory diseases, a disaster increases the risk of acute exacerbation. Meanwhile, for people with cancer, cardiovascular diseases and diabetes there is an increased risk of their illness exacerbating, which can ...

Adiponectin: a relevant player in obesity-related colorectal cancer?
Obesity is a condition characterised by an abnormally elevated mass of body fat. The past decades have seen a dramatic rise in the worldwide incidence of obesity due to lifestyle changes that have led to an overall reduced physical activity and an increase in the intake of excessive and/or highly caloric or processed foods. As a consequence, obesity represents nowadays a major global health concern. In particular, several epidemiological studies have linked obesity to a shortened lifespan due primarily to a higher risk for the development of chronic pathologies that include cardiovascular complications such as high blood p...
