Empagliflozin reduces blood pressure in patients with type 2 diabetes and hypertension.

Objective: To investigate the efficacy, safety, and tolerability of empagliflozin in patients with type 2 diabetes and hypertension.

Research Design And Methods: Patients (N = 825) with type 2 diabetes and hypertension (mean seated systolic blood pressure [SBP] 130-159 mmHg and diastolic blood pressure [DBP] 80-99 mmHg) were randomized (double blind) to 10 mg or 25 mg empagliflozin or placebo once daily for 12 weeks.

Results: At week 12, adjusted mean difference versus placebo in change from baseline in mean 24-h SBP (ambulatory blood pressure monitoring [ABPM]) was -3.

Inhibition of cyclooxygenase-2 causes regression of gastric adenomas in trefoil factor 1 deficient mice.

Cyclooxygenase-2 (Cox-2) expression is a marker of reduced survival in gastric cancer patients, and inhibition of Cox-2 suppresses gastrointestinal carcinogenesis in experimental animal models. To investigate the role of Cox-2 in gastric carcinogenesis in vivo, we utilized trefoil factor 1 (Tff1) deficient mice, which model the neoplastic process of the stomach by developing gastric adenomas with full penetrance. These tumors express Cox-2 protein and mRNA, and we have now investigated the effects of genetic deletion of the mouse Cox-2 gene [also known as prostaglandin-endoperoxide synthase 2 (Ptgs2)] and a Cox-2 selective drug celecoxib.

PPARdelta is pro-tumorigenic in a mouse model of COX-2-induced mammary cancer.

Cyclooxygenase-2 (COX-2), overexpressed in inflammatory conditions and cancer, regulates angiogenesis and tumorigenesis via the production of biologically active prostanoids. Previously, we showed that COX-2 over-expression in the mammary gland of transgenic mice induces an angiogenic switch and transforms the mammary epithelium into invasive mammary carcinoma. Since COX-2-derived prostanoids can activate the nuclear receptor PPARdelta, we crossed Ppardelta(-/-) mice with COX-2 transgenic mice in the FVB/N background.

VEGF-C and COX-2 expression in papillary thyroid cancer.

In papillary thyroid cancer (PTC), age appears to be the most important single prognostic factor. Another characteristic feature is the lack of association between survival and lymph node metastases. Earlier, we found that expression of cyclooxygenase-2 (COX-2) is higher in older PTC patients, in agreement with the finding that older patients have a worse prognosis.

COX-2 inhibitors and genetic background reduce mammary tumorigenesis in cyclooxygenase-2 transgenic mice.

Cyclooxygenase-2 (COX-2) overexpression is a widely recognized feature of human breast cancer and inhibitors of the enzyme have antitumor effects in a subset of tumor settings. Previously, we demonstrated that direct overexpression of COX-2 under control of the mammary-specific MMTV promoter/enhancer, was itself oncogenic and lead to the induction of mammary tumors in multiparous, outbred CD1 mice. In the present study, we provide evidence that COX-2 dependent tumor progression can also be studied in FVB/N, an inbred strain widely used for analysis of breast cancer progression.

Cytoplasmic HuR expression is a prognostic factor in invasive ductal breast carcinoma.

HuR is a ubiquitously expressed mRNA-binding protein. Intracellular localization of HuR is predominantly nuclear, but it shuttles between the nucleus and the cytoplasm. In the cytoplasm it can stabilize certain transcripts.

Cyclooxygenase-2 expression and effect of celecoxib in gastric adenomas of trefoil factor 1-deficient mice.

Expression of cyclooxygenase-2 (Cox-2) is elevated in gastric adenocarcinomas and precursor lesions leading to this disease. Mice deficient for trefoil factor 1 (TFF1) develop a pyloric adenoma with full penetrance. Because inhibition of Cox-2 suppresses tumor growth in several animal models, we studied expression of Cox-2 and effect of a selective Cox-2 inhibitor celecoxib in gastrointestinal tissues of the TFF1-deficient mice.
