Health-Related Quality of Life With Ulipristal Acetate for Treatment of Uterine Leiomyomas: A Randomized Controlled Trial.

OBJECTIVE: To investigate effects of ulipristal acetate on health-related quality of life (QOL) and symptom severity in women with symptomatic uterine leiomyomas and abnormal uterine bleeding. METHODS: Women were randomized to ulipristal (5 mg, 10 mg) or placebo in two phase 3, multicenter, double-blind, placebo-controlled trials (VENUS I and II). Health-related QOL and symptom severity were assessed at baseline, and over one (VENUS I and II) and two (VENUS II) 12-week treatment courses using the Uterine Fibroid Symptom Health-Related Quality of Life questionnaire. In pooled VENUS I and II data, change from baseline to the end of the first course for each Uterine Fibroid Symptom Health-Related Quality of Life scale was analyzed, including a Revised Activities subscale that measured physical and social activities. The proportion of women achieving meaningful change in the Symptom Severity (20 or more points), Health-Related QOL Total (20 or more points), and Revised Activities (30 or more points) scales was calculated. In VENUS II data, change from baseline to the end of each course in each scale was analyzed for each treatment arm. RESULTS: In pooled analyses, the intent-to-treat population included 589 patients (placebo, n=169; ulipristal 5 mg, n=215; ulipristal 10 mg, n=205). Significantly greater improvements from baseline in all Uterine Fibroid Symptom Health-Related Quality of Life scales were observed with both ulipristal doses compared with placebo (P<.001). A meaningful change in Revised Activities was achieved by 51 patients receiving placebo (34.9%), compared with 144 (73.5%; OR 5.0 [97.5% CI 2.9-8.6]) and 141 (80.6%; OR 7.9 [97.5% CI 4.3-14.6]) patients receiving ulipristal 5 mg, and 10 mg, respectively. In VENUS II, at end of courses 1 and 2, both ulipristal doses demonstrated significant improvements from baseline compared with placebo for all Uterine Fibroid Symptom Health-Related Quality of Life scales (P<.01). Mean Revised Activities scores showed that beneficial ulipristal effects were maintained in course 2, and improvements occurred on switching to ulipristal; results for other scales were similar. CONCLUSION: Ulipristal was associated with significant improvements in health-related QOL and symptom severity compared with placebo for women with symptomatic uterine leiomyomas.

SCT Promoter Methylation is a Highly Discriminative Biomarker for Lung and Many Other Cancers.

Aberrant DNA methylation has long been implicated in cancers. In this work we present a highly discriminative DNA methylation biomarker for non-small cell lung cancers and fourteen other cancers. Based on 69 NSCLC cell lines and 257 cancer-free lung tissues we identified a CpG island in SCT gene promoter which was verified by qMSP experiment in 15 NSCLC cell lines and 3 immortalized human respiratory epithelium cells. In addition, we found that SCT promoter was methylated in 23 cancer cell lines involving >10 cancer types profiled by ENCODE. We found that SCT promoter is hyper-methylated in primary tumors from TCGA lung cancer cohort. Additionally, we found that SCT promoter is methylated at high frequencies in fifteen malignancies and is not methylated in~1000 non-cancerous tissues across >30 organ types. Our study indicates that SCT promoter methylation is a highly discriminative biomarker for lung and many other cancers.

Novel Foxo1-dependent transcriptional programs control T(reg) cell function.

Regulatory T (T(reg)) cells, characterized by expression of the transcription factor forkhead box P3 (Foxp3), maintain immune homeostasis by suppressing self-destructive immune responses. Foxp3 operates as a late-acting differentiation factor controlling T(reg) cell homeostasis and function, whereas the early T(reg)-cell-lineage commitment is regulated by the Akt kinase and the forkhead box O (Foxo) family of transcription factors. However, whether Foxo proteins act beyond the T(reg)-cell-commitment stage to control T(reg) cell homeostasis and function remains largely unexplored. Here we show that Foxo1 is a pivotal regulator of T(reg )cell function. T(reg) cells express high amounts of Foxo1 and display reduced T-cell-receptor-induced Akt activation, Foxo1 phosphorylation and Foxo1 nuclear exclusion. Mice with T(reg)-cell-specific deletion of Foxo1 develop a fatal inflammatory disorder similar in severity to that seen in Foxp3-deficient mice, but without the loss of T(reg) cells. Genome-wide analysis of Foxo1 binding sites reveals ~300 Foxo1-bound target genes, including the pro-inflammatory cytokine Ifng, that do not seem to be directly regulated by Foxp3. These findings show that the evolutionarily ancient Akt-Foxo1 signalling module controls a novel genetic program indispensable for T(reg) cell function.
