Use of peptide nucleic acid probe to determine telomere dynamics in improving chromosome analysis in genetic toxicology studies.

Genetic toxicology, strategically located at the intersection of genetics and toxicology, aims to demystify the complex interplay between exogenous agents and our genetic blueprint. Telomeres, the protective termini of chromosomes, play instrumental roles in cellular longevity and genetic stability. Traditionally karyotyping and fluorescence in situ hybridisation (FISH), have been indispensable tools for chromosomal analysis following exposure to genotoxic agents.

Role of Mitogen-Activated Protein (MAP) Kinase Pathways in Metabolic Diseases.

Physiological processes that govern the normal functioning of mammalian cells are regulated by a myriad of signalling pathways. Mammalian mitogen-activated protein (MAP) kinases constitute one of the major signalling arms and have been broadly classified into four groups that include extracellular signal-regulated protein kinase (ERK), c-Jun N-terminal kinase (JNK), p38, and ERK5. Each signalling cascade is governed by a wide array of external and cellular stimuli, which play a critical part in mammalian cells in the regulation of various key responses, such as mitogenic growth, differentiation, stress responses, as well as inflammation.

Breast cancer is the most common cause of malignancy and the second most common cause of death due to cancer in women. This heterogeneous disease is currently broadly classified as estrogen receptor (ER), progesterone receptor (PR) positive luminal tumors, human epidermal growth factor receptor 2 (HER2) amplified tumors and triple-negative breast cancers (TNBC). Phytochemicals are proven to be promising anti-cancer chemotherapeutics agents with minimal cytotoxic effects on normal cells.

Towards equitable representation in long-term residential care: widening the circle to ensure "essential voices" in research teams.

The COVID-19 pandemic exposed long-standing inequities in Canada's long-term residential care (LTRC) sector with life-threatening consequences. People from marginalized groups are overrepresented among those who live in, and work in LTRC facilities, yet their voices are generally silenced in LTRC research. Concerns about these silenced voices have sparked debate around ways to change LTRC policy to better address long-standing inequities and enhance the conditions that foster dignity for those who live and work in LTRC.

Our analysis of 21 policies that regulate long-term care in four Canadian Provinces reveal differences in their portrayal of residents' families.

TB disease patterns by HIV and diabetes status.

TB is commonly categorised as pulmonary (PTB) or extrapulmonary TB (EPTB). Knowledge of TB disease patterns (PTB and/or EPTB) and determining risk factors remains limited. This was a prospective cohort study using point-of-care ultrasound (POCUS) in Indian patients with presumed TB.

Role of Xeroderma pigmentosum D (XPD) protein in genome maintenance in human cells under oxidative stress.

Xeroderma pigmentosum D (XPD) protein plays a pivotal role in the nucleotide excision repair pathway. XPD unwinds the local area of the damaged DNA by virtue of constituting transcription factor II H (TFIIH) and is important not only for repair but also for basal transcription. Although cells deficient in XPD have shown to be defective in oxidative base-lesion repair, the effects of the oxidative assault on primary fibroblasts from patients suffering from Xeroderma Pigmentosum D have not been fully explored.

Effects of dietary interventions on telomere dynamics.

Telomeres play a critical role in maintaining cellular fate through tight regulation of cell division and DNA damage or repair. Over the years, it is established that biological ageing is defined by a gradual derangement in functionality, productivity, and robustness of biological processes. The link between telomeres and ageing is highlighted when derangement in telomere biology often leads to premature ageing and concomitant accompaniment of numerous age-associated diseases.
