TL;DR: Ch Chromatin immunoprecipitations show that PRMT5 is associated specifically with the transcription start site region of the cyclin E1 promoter, providing the first direct experimental evidence that a type II arginine methylase is involved in the control of transcription and proliferation.
Abstract: We have identified previously a repressor element in the transcription start site region of the cyclin E1 promoter that periodically associates with an atypical, high molecular weight E2F complex, termed CERC. Purification of native CERC reveals the presence of the type II arginine methyltransferase PRMT5, which can mono- or symetrically dimethylate arginine residues in proteins. Chromatin immunoprecipitations (ChIPs) show that PRMT5 is associated specifically with the transcription start site region of the cyclin E1 promoter. ChIP analyses also show that this correlates with the presence on the same promoter region of arginine-methylated proteins including histone H4, an in vitro substrate of PRMT5. Consistent with its presence within the repressor complex, forced expression of PRMT5 negatively affects cyclin E1 promoter activity and cellular proliferation, effects that require its methyltransferase activity. These data provide the first direct experimental evidence that a type II arginine methylase is involved in the control of transcription and proliferation.

TL;DR: Results suggest that increased SDF‐1 production by MSCs acts in an autocrine manner and is required for migratory responses to tumor cells.
Abstract: Distinct signals that guide migration of mesenchymal stem cells (MSCs) to specific in vivo targets remain unknown. We have used rat MSCs to investigate the molecular mechanisms involved in such migration. Rat MSCs were shown to migrate to tumor microenvironment in vivo, and an in vitro migration assay was used under defined conditions to permit further mechanistic investigations. We hypothesized that distinct molecular signals are involved in the homing of MSCs to tumor sites and bone marrow. To test this hypothesis, gene expression profiles of MSCs exposed in vitro to conditioned medium (CM) from either tumor cells or bone marrow were compared. Analysis of the microarray gene expression data revealed that 104 transcripts were upregulated in rat MSCs exposed to CM from C85 human colorectal cancer cells for 24 hours versus control medium. A subset of 12 transcripts were found to be upregulated in rat MSCs that were exposed to tumor cell CM but downregulated when MSCs were exposed to bone marrow CM and included CXCL-12 (stromal cell-derived factor-1 [SDF-1]), CXCL-2, CINC-2, endothelial cell specific molecule-1, fibroblast growth factor-7, nuclear factor-kappaB p105, and thrombomodulin. Exposure to tumor cell CM enhanced migration of MSCs and correlated with increased SDF-1 protein production. Moreover, knockdown of SDF-1 expression in MSCs inhibited migration of these cells to CM from tumor cells, but not bone marrow cells, confirming the importance of SDF-1 expression by MSCs in this differential migration. These results suggest that increased SDF-1 production by MSCs acts in an autocrine manner and is required for migratory responses to tumor cells.

TL;DR: The results underscore the risk posed by cultural adjustment problems, the potential for progressive deterioration of this population's mental health, and the need for culturally appropriate mental health services.
Abstract: OBJECTIVES: In this study, the prevalence of and risk factors for 12 psychiatric disorders were examined by sex and ethnicity (Indian vs non-Indian) among Mexican migrant farm-workers working in Fresno County, California. METHODS: Subjects aged 18 through 59 years were selected under a cluster sampling design (n = 1001). A modified version of the Composite International Diagnostic Interview was used for case ascertainment. The effects of sociodemographic and acculturation factors on lifetime psychiatric disorders were tested. RESULTS: Lifetime rates of any psychiatric disorder were as follows: men, 26.7% (SE = 1.9); women, 16.8% (SE = 1.7); Indians, 26.0% (SE = 4.5); non-Indians, 20.1% (SE = 1.3). Total lifetime rates were as follows: affective disorders, 5.7%; anxiety disorders, 12.5%; any substance abuse or dependence, 8.7%; antisocial personality, 0.2%. Lifetime prevalence of any psychiatric disorder was lower for migrants than for Mexican Americans and for the US population as a whole. High acculturation and primary US residence increased the likelihood of lifetime psychiatric disorders. CONCLUSIONS: The results underscore the risk posed by cultural adjustment problems, the potential for progressive deterioration of this population's mental health, and the need for culturally appropriate mental health services.

TL;DR: In this article, the authors developed and evaluated an intervention designed to encourage successful coping with stigma and found that people perceive and experience stigma and that these perceived perceptions affect their coping with mental illnesses.
Abstract: The stigma of mental illness has been shown to be a strong negative feature in the lives of many people with mental illnesses and their families. As a consequence it makes sense to undertake efforts to reduce the negative impact of stigma on the lives of people who experience it. In keeping with this idea we set out to develop and evaluate an intervention designed to encourage successful coping with stigma. Specifically, we constructed measures designed to assess the experience of stigma and to develop a pilot intervention designed to interrupt some of the negative consequences of stigma. To achieve this goal we studied people attending a clubhouse program, randomly assigning participants to intervention and control groups in the context of pretest-postest design. In a unique feature we also followed up the participants two year following the pre-test when all participants had the opportunity to experience the intervention. We found that people perceive and experience stigma and that these percep...

TL;DR: At doses of 0.3 mg/kg or more per week, intravenous efalizumab produced significant clinical and histologic improvement in psoriasis, which correlated with sustained serum efalIZumab levels and T-cell CD11a saturation and down-modulation.
Abstract: Background Leukocyte function–associated antigen 1 (LFA-1), consisting of CD11a and CD18 subunits, plays an important role in T-cell activation and leukocyte extravasation. Objective To test whether blocking CD11a decreases immunobiologic and clinical activity in psoriatic plaques. Design Open-label, multicenter, dose escalation study. Patients Thirty-nine patients with moderate-to-severe psoriasis. Intervention Intravenous infusions of efalizumab, a humanized anti-CD11a monoclonal antibody, for 7 weeks at doses of 0.1 mg/kg every other week or 0.1 mg/kg weekly (category 1), 0.3 mg/kg weekly (category 2), and 0.3 increasing to 0.6 or 1.0 mg/kg weekly (category 3). Skin biopsies were performed on days 0, 28, and 56. Main Outcome Measures Serum efalizumab levels, levels of total and unoccupied T-cell CD11a, T cell counts, epidermal thickness, cutaneous intercellular adhesion molecule 1 (ICAM-1) and keratin 16 (K16) expression, Psoriasis Area and Severity Index (PASI) scores. Results Dose-response relationships were observed for pharmacokinetics and pharmacodynamic measures. Category 1 failed to maintain detectable serum efalizumab or T cell CD11a down-modulation between doses. Category 2 achieved both. Category 3 achieved both and additionally maintained sustained T-cell CD11a saturation between doses. A dose-response relationship was also observed clinically and histologically. The mean decrease in the PASI score was 47% in category 3, 45% in category 2, and 10% in category 1 ( P Conclusions At doses of 0.3 mg/kg or more per week, intravenous efalizumab produced significant clinical and histologic improvement in psoriasis, which correlated with sustained serum efalizumab levels and T-cell CD11a saturation and down-modulation.
