Aging is known to lead to the impaired recovery of muscle after disuse as well as the increased susceptibility of the muscle to damage. Here, we show that, in the older rats, reloading after disuse atrophy, causes the damage of the muscle fibers and the basement membrane (BM) that structurally support the muscle fibers. Male Wistar rats of 3-(young) and 20-(older) months of age were subjected to hindlimb-unloading for 2weeks followed by reloading for a week. In the older rats, the soleus muscles showed necrosis and central nuclei fiber indicating the regeneration of muscle fibers...

BACKGROUND: Congenital heart defects (CHDs) are the most common birth defects in the United States, and the population of individuals living with CHDs is growing. Though CHD prevalence in infancy has been well characterized, better prevalence estimates among children and adolescents in the United States are still needed. METHODS: We used capture-recapture methods to estimate CHD prevalence among adolescents residing in 11 New York counties. The three data sources used for analysis included Statewide Planning and Research Cooperative System (SPARCS) hospital inpatient records, SPARCS outpatient records, and medical records provided by seven pediatric congenital cardiac clinics from 2008 to 2010...

Activity of endogenous promoters can be altered by including additional responsive elements (REs). These elements can be responsive to features of the tumor environment or alternatively to signaling pathways specifically activated in cancer cells. These REs incorporated into tumor-specific promoters can improve cancer targeting, the replicative capacity, and lytic activity of conditionally replicative adenovirus. Here we outline an approach to incorporate hypoxia and inflammation REs into a specific fragment of the SPARC promoter and the steps to clone a nucleosome positioning sequence (NPS ) identified in the osteocalcin promoter that contains a Wnt RE upstream of a heterologous synthetic promoter...

Here we describe a collection of methods that have been adapted to isolate and modify tumor-specific promoters (TSPs ) to drive viral replication for cancer therapy and other uses. We will describe as examples the secreted protein acidic and rich in cysteine (SPARC ) and the protease-activated receptor-1 (PAR-1) promoter. We outline strategies to select appropriate TSPs using bioinformatics resources and the methods utilized in their subsequent cloning, assessment of transcriptional activity, and their use in conditionally replicative oncolytic adenoviruses ...

AIM: The aim was to investigate the effect of miR-377 on DNMT1 expression and cancer phenotype in pancreatic cancer cells. MATERIALS & METHODS: Real-time PCR, luciferase assay, MTT and Annexin-PI staining were used. RESULTS: Decreased miR-377 and increased DNMT1 (verified as a target for mir-377) levels in pancreatic cancer tissues and cell lines in comparison with normal tissues was confirmed to be influenced by promoter methylation. Also hypermethylation of BNIP3, SPARC, TFPI2 and PENK promoters was observed in tumor samples but not in normal tissues which negatively correlated with their expression...

INTRODUCTION: During laparoscopic cholecystectomy (LC), common bile duct (CBD) visualization either directly or with cholangiography (IOC) is less routine. Cholangiography can be used to identify and possibly prevent bile duct injury (BDI), which is a dreaded complication of cholecystectomy. The purpose of our study was to evaluate the trend of IOC/CBD exploration and BDI during LC for benign disease. METHODS: A state-wide database (SPARCS) was used to identify all LC for benign biliary non-obstructive and obstructive disease between 2000 and 2014 in the state of New York...

Secreted protein acidic and rich in cysteine (SPARC) is a secreted protein which is involved in various biological processes. SPARC expression is associated with tumor metastasis and poor prognosis in several types of cancer. However, the SPARC-induced signaling pathway was not fully understood in head and neck cancer. In this study, our results showed that SPARC treatment promoted cell proliferation and migration in head and neck cancer cell lines FaDu and Detroit 562. In addition, SPARC induced expression of epithelial mesenchymal transition (EMT) regulators, including Slug, Snail, and Twist in Detroit 562...

Fibrotic stroma and tumor-promoting pancreatic stellate cells (PSCs), critical characters in the pancreatic ductal adenocarcinoma (PDA) microenvironment, promote a tumor-facilitating environment that simultaneously prevents drug penetration into tumor foci and stimulates tumor growth. Nab-PTX, a human serum albumin (HSA) nanoparticle of paclitaxel (PTX), indicates enhanced matrix penetration in PDA probably due to its small size in vivo and high affinity of HSA with secreted protein acidic and rich in cysteine (SPARC), overexpressed in the PDA stroma...
