miR-133a restoration curtailed growth and metastasis of lung cancer cells in vitro and in vivo. Moreover, miR-133a downregulated PTBP1 expression, whereas overexpression of PTBP1 attenuated the suppressive effect of miR-133a on lung cancer cell aggressiveness. The level of methylation modification of miR-133a was reduced in lung cancer cells. KDM5C inhibited the expression of miR-133a by promoting the demethylation modification of its promoter histone.
Histone demethylase KDM5C inhibits the expression of miR-133a by elevating the demethylation modification of the promoter histone of miR-133a, thereby promoting the expression of PTBP1, which finally accelerates lung cancer cell growth and metastasis.

We conducted the study to elucidate how LncRNA LINC00941 affects colon cancer progression and its possible regulatory mechanism.
The expression level of LINC00941 in colon cancer tissues and cells was detected by qRT-PCR. The function of LINC00941 on colon cancer cell proliferation, migration, and invasion was detected by CCK-8 and Transwell assay respectively. The target interactions among LINC00941, miR-205-5p, and MYC were further confirmed by dual-luciferase reporter gene assays and RNA pull-down experiments. Meanwhile, in vivo experiments were carried out to study the role of LINC00941 in the xenotransplantation model.
LINC00941 expression level was elevated in colon cancer tissues and cells. LINC00941 overexpression accelerated proliferation, migration, and invasion of colon cancer cells, while the LINC00941 knockdown showed the opposite results. In addition, LINC00941 regulated the expression of MYC by sponging miR-205-5p as a competitive endogenous RNA, and miR-205-5p knockdown reversed the tumor inhibition of LINC00941 knockdown on colon cancer cells. Xenograft model assay confirmed that LINC00941 silencing could inhibit colon cancer cell growth and metastasis.
LINC00941 may markedly promote colon cancer progression by acting on the miR-205-5p/MYC axis as a ceRNA, which offers novel clues for lncRNA to guide the treatment and prognosis of colon cancer.

This study investigated the function and molecular mechanisms of miR-744-5p in multiple myeloma (MM).
miR-744-5p and SRY-related high-mobility-group box 12 (SOX12) expression in clinical tissues and MM cells was monitored by quantitative real-time polymerase chain reactions and Western blot. miR-744-5p expression in MM cells was regulated by transfection. Cell proliferation was researched by cell counting kit-8 assay and plate clone formation experiment. Transwell experiment was utilized for migration and invasion detection. Glycolysis test was conducted for the detection of glucose uptake and lactate production of MM cells. The relationship between miR-744-5p and SOX12 was determined by dual-luciferase reporter gene assay and RNA pull-down experiment. In vivo experiment was conducted using nude mice.
miR-744-5p expression was reduced in MM patients (
<0.01). Low miR-744-5p expression was associated with lower 60-month survival in MM patients (
=0.0402). miR-744-5p overexpression inhibited MM cells proliferation, invasion, migration, glucose uptake, lactate production, and epithelial mesenchymal transformation (EMT) (
<0.01). miR-744-5p directly inhibited SOX12 expression. miR-744-5p silencing promoted MM cells proliferation, invasion, migration, glucose uptake, lactate production, and EMT by elevating SOX12 (
<0.01). miR-744-5p inhibited the growth of MM xenograft tumors in vivo (
<0.001).
miR-744-5p inhibits MM cells proliferation, invasion, migration, EMT, and glycolysis by targeting SOX12/Wnt/β-catenin.

African American (AA) male survivors of strokes or transient ischemic attacks (TIA) have the highest risk of recurrent stroke when compared to other racial-ethnic men. read more However, there is a paucity of evidence-based strategies, including organizational, educational, or behavioral interventions, that targets secondary stroke risk reduction in AA men.
Targeted Management for Reducing Stroke Risk (TEAM) is an ongoing, 6-month prospective, randomized controlled trial that will determine whether a curriculum-guided self-management approach, using peer dyads (men who had a stroke or TIA and their care partners) will improve post-stroke care in AA men.
The study sample will consist of 160 AA men who have experienced a stroke or TIA within 5 years, randomized to TEAM or Wait-list control group. The primary outcome changes in systolic blood pressure (BP) and high-density lipoprotein (HDL), while secondary outcomes include diastolic BP, total cholesterol, low-density lipoprotein, triglycerides, and glycemic control for diabetics. We hypothesize that AA men in TEAM will have significantly lower systolic BP and higher HDL when compared to AA men in the Wait-list control group at 6-month.
Persistent disparities for stroke burden in AA men highlight the need for novel interventions to promote secondary stroke-risk reduction. Building on promising pilot data, TEAM uses a group format, with a nurse and patient co-led intervention focused on AA men and family needs, practice in problem-solving, and attention to emotional and role management. In addition, the TEAM approach may help reduce stroke risk factors and health disparities in AA men.

There is a compelling rationale that effective communication between hospital allied health and primary care practitioners may improve the quality and continuity of patient care. It is not known which methods of communication to use, nor how effectively they facilitate the transition of care when a patient is discharged home from hospital. Our systematic review aims to investigate the methods and effectiveness of communication between hospital allied health and primary care practitioners.
Systematic review of quantitative and qualitative studies with narrative synthesis. Medline, CINAHL, EMBASE, PsycInfo and Proquest Nursing and Allied Health Sources were searched from January 2003 until January 2020 for studies that examined hospital-based allied health professionals communicating with community-based primary care practitioners. Risk of bias in the different study designs was appraised using recognized tools and a content analysis conducted of the methodologies used.
From the located 12,281 papers (duplicates removed), 24 studies met the inclusion criteria with hospital allied health communicating in some form with primary care practitioners.
