hTERT Promoter Regulation by Differentiation Mechanisms vs Telomerase Activity in Somatic, Embryonic, and Cancerous Cells

Received: 02 February 2019;  Published: 04 April 2019;  doi: 10.21926/obm.geriatr.1902045

Abstract

Telomere shortening in the somatic cells is one of the most well-documented factors of cellular ageing. Telomeres are composed of tandem hexanucleotide repeats that protect cells from unwanted recombination mechanisms, secure the ends of chromosomes and their stability, and are responsible for limited division capacity. Telomerase is an enzymatic ribonucleoprotein complex, present in embryonic cells, adult stem cells, and germinal progenitors, whose function is to extend the telomeres length by adding the lost tand [...]

Does Dementia Increase the Risk of Dental Decay?

Received: 09 January 2019;  Published: 21 March 2019;  doi: 10.21926/obm.geriatr.1901040

Abstract

The amount of patients who suffer with dementia is set to rise with an ageing population. As well as living longer, patients will be retaining their natural teeth into their later life and will be less reliant on dentures. From both the current evidence available in the literature, and anecdotally from clinicians experienced in treating patients with dementia, it can be concluded that on balance, patients with dementia appear to be at a greater risk from dental caries (dental decay). However, more research in this [...]

Behavioural and Complementary Interventions for Healthy Neurocognitive Aging

Received: 30 November 2018;  Published: 20 March 2019;  doi: 10.21926/obm.geriatr.1901039

Abstract

Background: While the percent of persons 65 and older is expected to increase to 17% of the world’s population by 2050, this increase in longevity does not necessarily suggest a parallel increase in health status. While aging is an inevitable aspect of living, there are factors which can accelerate morbidity and mortality, as well as factors likely to promote a healthy transition into longevity. This paper addresses behavioural and complementary interventions for healthy neurocognitive aging. Specific evidence-base [...]

Sporadic Alzheimer Disease and That Developing in Down’s Syndrome: The Immune System Attacking Self Rather Than Suppressing Infectious Disease Invaders, Toll Like Receptors Triggering Excessive Cytosolic Calcium, Excess Calcineurin Activation, Overexpression of Regulator of Calcineurin1, Runaway Beta-Amyloid Production, Synaptic Loss, Destructive Inflammation and Dementia

Received: 29 August 2018;  Published: 26 February 2019;  doi: 10.21926/obm.geriatr.1901035

Abstract

Alzheimer Disease may result from excessive stimulation of the innate immune system from development of underlying opportunistic infections and impaired age related self-recognition as non-self, due to immunodeficiency and immunosenescence, resulting in excessive inflammation and runaway Beta-amyloid production (a component of the innate immune system) causing cytosolic calcium overload. Excessive cytosolic calcium may cause over activation of calcineurin and inactivation of cis-trans prolyl isomerase (Pin1), with [...]

Cell Senescence, Telomerase, and Senolytic Therapy

Received: 31 December 2018;  Published: 15 February 2019;  doi: 10.21926/obm.geriatr.1901034

Abstract

The consensus that cell senescence plays a role in age-related disease has prompted a number of potential clinical interventions, including attempts to reset cell senescence and attempts to remove senescent cells from aging tissues. The latter approach, senolytic therapy, has attracted considerable attention, but both theoretical considerations and published data suggest that the clinical benefits will be transient and that senolytic therapies will likely accelerate long-term degenerative disease. We review the ove [...]

This is perfectly compatible with the prevailing view that aging is the inevitable result of multiple degenerative processes that cannot be treated effectively as they are, in themselves, inevitable and irreversible. This interpretation of aging clashes with a mass of data and arguments that, conversely, indicate that aging is a specific physiological function, favoured by supra-individual natural [...]

Received: 11 December 2016;  Published: 06 January 2017;  doi: 10.21926/obm.geriatr.1701001

Abstract

Geriatrics, and much of clinical medicine, is on the verge of a profound transformational shift. Until now, there has been a sharp conceptual divide between diseases which can be readily and effectively treated, and diseases which we have thought to be beyond clinical intervention. In the first disease category, are many of the most common infections that respond to antibiotics and immunizations. We have made dramatic changes in the demographics and the mortality of many such treatable diseases. At the other extrem [...]

Received: 10 October 2025;  Published: 14 January 2026;  doi: 10.21926/obm.genet.2601325

Abstract

Stem cell-derived exosomes (SDEs) have emerged as revolutionary mediators in cancer immunotherapy, offering unprecedented potential to reprogram the immunosuppressive tumor immune microenvironment (TIME). These nano-sized extracellular vesicles, laden with non-coding RNAs (ncRNAs), serve as natural biocompatible carriers, capable of orchestrating immune cell dynamics, stromal remodeling, and tumor cell fate. Unlike their tumor-derived counterparts, which often propagate oncogenic signals, SDEs uniquely harbor immun [...]

Abstract

Human ring chromosomes (RCs) constitute one of the rarest described inborn chromosomal rearrangements. At first, they seem to be just another subgroup of structural chromosomal aberrations like translocations, inversions, or insertions. However, RCs are more complex, as they almost always occur in conjunction with a mosaic karyotype constitution, resulting in mosaic monosomy of the affected chromosome. Most likely due to the latter effect, a genotype-phenotype correlation is still not available. To proceed with sol [...]

Potential CRISPR-Cas9-based Antiviral Activity Against Hepatitis C Virus in Liver Cancer

Received: 04 July 2024;  Published: 28 February 2025;  doi: 10.21926/obm.genet.2501287

Abstract

Hepatitis C virus (HCV) is a primary global health concern, and though therapeutic options have improved, no very effective vaccine is available despite decades of research. The health and vitality of the organism are related to the result of homeostatic regulation of the internal environment. In contrast, it follows that disruption of homeostatic mechanisms leads to disease, particularly in liver cancer. Since HCV can rapidly mutate to evade the immune response, an effective HCV vaccine must rely on the identifica [...]
