Intestinal Gucy2c Prevents Tgf-Β Secretion Coordinating Desmoplasia And Hyperproliferation In Colorectal Cancer., Ahmara V Gibbons, Jieru Egeria Lin, Gilbert Won Kim, Glen P Marszalowicz, Peng Li, Brian Arthur Stoecker, Erik S Blomain, Satish Rattan, Adam E. Snook, Stephanie Schulz, Scott A Waldman

Tumorigenesis is a multistep process that reflects intimate reciprocal interactions between epithelia and underlying stroma. However, tumor-initiating mechanisms coordinating transformation of both epithelial and stromal components are not defined. In humans and mice, initiation of colorectal cancer is universally associated with loss of guanylin and uroguanylin, the endogenous ligands for the tumor suppressor guanylyl cyclase C (GUCY2C), disrupting a network of homeostatic mechanisms along the crypt-surface axis. Here, we reveal that silencing GUCY2C in human colon cancer cells increases Akt-dependent TGF-β secretion, activating fibroblasts through TGF-β type I receptors and Smad3 phosphorylation. In turn, activating TGF-β signaling induces fibroblasts to …

Abstract: Background: Acute pulmonary embolism (PE) is a life-threatening condition. Making a definitive diagnosis with radiologic studies may delay therapy or be unsafe for the patient. Echocardiography is readily available and can suggest PE by demonstrating right ventricular (RV) dysfunction. McConnell’s sign on echocardiogram (ECHO-CG) (RV dysfunction with characteristic sparing of the apex) has been reported to have high sensitivity and specificity for the diagnosis of acute PE. It is hypothesized that McConnell’s sign on ECHO-CG in patients hospitalized with suspected acute PE would have a high positive predictive value (PPV).
Methods: Data, from 2005 to 2010, were retrospectively collected …

Dabigatran, an alternative to warfarin for prevention of stroke with non-valvular atrial fibrillation (AF), offers advantages of a fixed dosage, minimal laboratory monitoring and limited medication interactions. Dabigatran requires dosage adjustment in renal dysfunction and is contraindicated if severe dysfunction. No identified dabigatran reversal agent exists.
Methods: As part of an ongoing quality initiative, novel anticoagulant associated adverse events (AE) are monitored at a dedicated neuroscience hospital.
Results: 5 cases of intracranial bleeding associated with dabigatran occurred from 12/2011-4/2012. All patients were on anticoagulation for AF, the most common dose of dabigatran was 150 mg BID. Mean admission values were …

Warfarin has been a mainstay of therapy for treatment and prevention of venous thromboembolic disease (VTED) and prevention of stroke and systemic embolism for over 50 years. Recent FDA approval of several novel oral anticoagulants has offered more extensive treatment options for management of these disease states.
The availability of the novel anticoagulants offers an attractive alternative to warfarin therapy for patients due to their convenience of use. In comparison to warfarin, dabigatran, rivaroxaban and apixaban offer: - a fixed dosage regimen
- a relatively small potential drug interaction profile
- minimal laboratory monitoring
- little to no dietary restrictions. …

Agonists of the transmembrane intestinal receptor guanylyl cyclase C (GCC) have recently attracted interest as promising human therapeutics. Peptide ligands that can specifically induce GCC signaling in the intestine include endogenous hormones guanylin and uroguanylin, diarrheagenic bacterial enterotoxins (ST), and synthetic drugs linaclotide, plecanatide, and SP-333. These agonists bind to GCC at intestinal epithelial surfaces and activate the receptor's intracellular catalytic domain, an event initiating discrete biological responses upon conversion of guanosine-5'-triphosphate to cyclic guanosine monophosphate. A principal action of GCC agonists in the colon is the promotion of mucosal homeostasis and its dependent barrier function. Herein, GCC agonists are …

Semaphorin 4D (Sema4D/CD100) is a 150-kDa transmembrane glycoprotein expressed by platelets and T-cells. When these cells are activated, Sema4D is cleaved proteolytically, generating a biologically active 120-kDa fragment (soluble Sema4D) capable of targeting receptors on platelets, B-cells, endothelial cells and tumor cells. However, its plasma levels and significance in heart failure (HF) have not been reported. In this study, we established an ELISA and detected soluble Sema4D in human plasma. In healthy controls, plasma Sema4D levels were higher in men than women (5.15±3.30 ng/mL, n = 63, vs. 4.19±2.39 ng/mL, n = 63, P

Metastatic disease is the principle cause of death from colorectal cancer. In that context, the most significant indicator of overall survival and therapeutic response to adjuvant chemotherapy is the presence of metastatic tumor cells in regional lymph nodes. Although histopathologic analysis of lymph nodes is central to all colorectal cancer staging paradigms, its prognostic and predictive value is limited. Indeed, about 30% of patients with histopathology-negative lymph nodes (pN0) die from metastatic disease, reflected by microscopic lymph node metastases that are overlooked by standard techniques. These unrecognized tumor cells are especially important when considering racial disparities in outcomes in colorectal …
