Due to an advanced understanding of cancer biology and the rapid development of genomic technologies, cancer has shifted from 200 diseases based on pathology (i.e., what a tumor looks like under the microscope) to thousands of diseases based on molecular tumor profiles (i.e., what a tumor looks like when its altered genome is interrogated). Most cancers arise from alterations to the genome, including changes in the number or structure of chromosomes and variations in a single building block of the genetic code.
Cells undergo a major epigenome reconfiguration when reprogrammed to human induced pluripotent stem cells (hiPS cells). However, the epigenomes of hiPS cells and human embryonic stem (hES) cells differ significantly, which affects hiPS cell function. These differences include epigenetic memory and aberrations that emerge during reprogramming, for which the mechanisms remain unknown.
Aneuploidies, and in particular, trisomies represent the most common genetic aberrations observed in human genetics today. To explore the presence of trisomies in historic and prehistoric populations we screen nearly 10,000 ancient human individuals for the presence of three copies of any of the target autosomes. We find clear genetic evidence for six cases of trisomy 21 (Down syndrome) and one case of trisomy 18 (Edwards syndrome), and all cases are present in infant or perinatal burials.
Declining worldwide or national stroke incidence rates are not always mirrored in disadvantaged, minority populations. Logistical barriers exist for effective measurement of incidence in minority populations; such data are required to identify targets for culturally appropriate interventions. In this comparative review, we aimed to examine whether “gold-standard” methodologies of stroke incidence studies are most effective for minority populations.
This paper argues for the enhancement of scoping review methods to incorporate Indigenous ways of knowing, being, and doing for more effective understandings of evidence of importance to Indigenous populations.
Conducting ethical and high-quality health research is crucial for informing public health policy and service delivery to reduce the high and inequitable burden of disease experienced by Aboriginal and Torres Strait Islander people.
Environmental epigenetics is a fast-growing field of scientific research attracting interest from key stakeholders in Indigenous health internationally, including researchers, clinicians, policymakers, and advocacy organisations. It is the study of how various external factors, including food, stress, and toxins, alter genetic expression, and could be biologically passed down to children (and potentially grandchildren).
Cardiovascular disease contributes significantly to disease burden among many Indigenous populations. However, data on stroke incidence in Indigenous populations are sparse. We aimed to investigate what is known of stroke incidence in Indigenous populations of countries with a very high Human Development Index locating the research in the broader context of Indigenous health.
High quality intervention research is needed to inform evidence-based practice and policy for Aboriginal and Torres Strait Islander communities. We searched for studies published from 2008-2020 in the PubMed database. A narrative review of intervention literature was conducted, where we identified researcher reported strengths and limitations of their research practice.
Within the vast majority of qualitative health research involving Indigenous populations, Indigenous people have been marginalised from research conceptualisation and conduct. This reflects a lack of regard for Indigenous ways of knowing, being, and doing, has served to perpetuate deficit narratives of Indigenous peoples’ health and wellbeing, and contributes to failure in addressing inequities as a result of ongoing colonisation and institutionalised oppression and racism.
