A framework for decolonising and diversifying biomedical sciences curricula: rediscovery, representation and readiness.

To date, most efforts to decolonise curricula have focussed on the arts and humanities, with many believing that science subjects are objective, unbiased, and unaffected by colonial legacies. However, science is shaped by both contemporary and historical culture. Science has been used to support imperialism, to extract and exploit knowledge and natural resources, and to justify racist and ableist ideologies.

Tetherin/BST2, a physiologically and therapeutically relevant regulator of platelet receptor signalling.

The reactivity of platelets, which play a key role in the pathogenesis of atherothrombosis, is tightly regulated. The integral membrane protein tetherin/bone marrow stromal antigen-2 (BST-2) regulates membrane organization, altering both lipid and protein distribution within the plasma membrane. Because membrane microdomains have an established role in platelet receptor biology, we sought to characterize the physiological relevance of tetherin/BST-2 in those cells.

Weight Reduction Goal Achievement Among Veterans With Mental Health Diagnoses.

Despite the use of weight management programs among veterans, the impact of mental health diagnoses on weight reduction goal achievement is unknown. We aimed to describe the prevalence and association of mental health diagnoses with a 5% weight reduction goal achievement. Logistic regression was used to describe the association between mental health diagnoses and weight reduction goal achievement at 6, 12, and 24 months among 402 veterans enrolled in a weight management program.

The tumor suppressor RhoBTB1 controls Golgi integrity and breast cancer cell invasion through METTL7B.

Background: RhoBTB1 and 2 are atypical members of the Rho GTPase family of signaling proteins. Unlike other Rho GTPases, RhoBTB1 and 2 undergo silencing or mutation in a wide range of epithelial cancers; however, little is known about the consequences of this loss of function.

Methods: We analyzed transcriptome data to identify transcriptional targets of RhoBTB2.

RNA interference approaches to examine Golgi function in animal cell culture.

The ability to deplete specific proteins from cells has transformed cell biology. Targeting of gene transcripts using RNA interference has allowed for a highly refined approach to the analysis of gene function that has been applied to all aspects of cell biology. Developments of the technology have reached a point where it is now a relatively trivial task to assess the role of an individual protein in a particular cell function.

Nucleo-cytosolic shuttling of FoxO1 directly regulates mouse Ins2 but not Ins1 gene expression in pancreatic beta cells (MIN6).

The Forkhead box transcription factor FoxO1 regulates metabolic gene expression in mammals. FoxO1 activity is tightly controlled by phosphatidylinositol 3-kinase (PI3K) signaling, resulting in its phosphorylation and nuclear exclusion. We sought here to determine the mechanisms involved in glucose and insulin-stimulated nuclear shuttling of FoxO1 in pancreatic β cells and its consequences for preproinsulin (Ins1, Ins2) gene expression.

FoxO1 is required for the regulation of preproglucagon gene expression by insulin in pancreatic alphaTC1-9 cells.

Forkhead/winged helix box gene, group O-1 (FoxO1) is a member of a family of nuclear transcription factors regulated by insulin-dependent phosphorylation and implicated in the development of the endocrine pancreas. We show here firstly that FoxO1 protein is expressed in both primary mouse islet alpha and beta cells. Examined in clonal alphaTC1-9 cells, insulin caused endogenous FoxO1 to translocate from the nucleus to the cytoplasm.

The expression of growth-arrest genes in the liver and kidney of the protein-restricted rat fetus.

During fetal life, there are periods of rapid cell proliferation, which are uniquely sensitive to nutritional perturbation. Feeding the pregnant rat a protein-restricted diet alters the growth trajectory of major fetal organs such as the kidney. By day 21 of gestation, the ratio of kidney weight to total body weight is reduced in the fetuses of dams fed a protein-deficient diet.

Prenatal protein restriction does not affect the proliferation and differentiation of rat preadipocytes.

Poor development in utero may favor the development of obesity in adulthood. Animal studies showed that embryo manipulation in vitro or nutritional insults during the embryonic and fetal stages of development may lead to obesity in adult life. We studied the in vitro proliferation and differentiation of adipocytes to investigate whether early protein restriction may program cell growth and development.

Technology and rural mental health.

In addition to the specific and pervasive rural issues of isolation and suitability of services, the rural mental health system faces many of the same problems as the health system in general: access and increasing costs. The introduction of technology adds the unknown dimensions of acceptability and feasibility. Technology has the potential to decrease the gap in services and improve education, support, and connectedness between the client and the provider.
