Heart failure (HF) progression has not been studied in pediatric patients as well as HF in patients with a normal ejection fraction (HFNEF). We aimed to evaluate galactin-3 in children with HFNEF and reduced ejection fraction (HFREF) and its correlation to disease severity and progression. This cross-sectional study involved 45 chronic HF patients taking G1a (23 HFNEF children) and G1b (22 HFREF children) compared to 45 age- and sex-matched controls (G2) subjected to history taking, Ross functional HF classification, conventional and tissue Doppler echocardiographic systolic and diastolic function assessment (FS%, E/A, S m, E m/A m, E/E m) and laboratory investigations [glomerular filtration rate, serum galactin-3 level (ELISA)]...

BACKGROUND/AIMS: Cirrhotic cardiomyopathy (CCM) is defined as an abnormal heart structure and function in cirrhotic patients. CCM includes systolic and diastolic dysfunction, electrophysiological abnormalities, and structural changes, both microscopic and macroscopic. Currently, there is no one diagnostic test that can identify patients with CCM. Evaluation of the validity of galactin-3 and brain natriuretic peptide (BNP) as biomarkers in the early detection of CCM in comparison to conventional echocardiography...

BACKGROUND: Proteomic approaches identifying biomarkers have been applied to asthma to only a very limited extent. METHODS: With an antibody array (RayBiotech, Norcross, GA, USA), the relative intensity and rank differences of 444 proteins were compared in 24 plasma samples obtained at age 3, 11 from children with and 12 without asthma diagnoses at ages 5 and 9. Protein candidates identified by antibody array were quantitated by ELISA in an enlarged sample. Proteins found to differentiate children with and without asthma were also examined for association with known Year 1 asthma risk factors, eczema, and wheeze...

We aim to investigate the expression profiles of galectin family genes (galectins-1, 2, 3, 4, 7, 8, 9, 10, and 11) in colorectal carcinomas. Messenger RNA (mRNA) expression of galectin family members (1, 2, 3, 4, 7, 8, 9, 10, and 12) was analyzed by real-time polymerase chain reaction in colorectal tissues from 201 patients (54 noncancer colorectal tissues, 49 adenomas, and 98 adenocarcinomas). Galectin-1 and galectin-3 protein expressions were determined by immunohistochemistry. In general, high galectin mRNA expression was noted in colorectal carcinomas in early stages of their pathogenesis...

Poor healing of epithelial wounds in cornea is a major clinical problem, leading to persistent epithelial defects and ulceration. The primary cause is poor cell migration over the wound. Carbohydrate-binding protein galectin-3 binds to extracellular matrixes (ECMs) and promotes lamellipodia formation by cross-linking to α3 integrin. Recombinant galectin-3 also facilitates wound healing in the rodent cornea. The purposes of the present experiments were to: (1) establish epithelial wound healing models in monkey corneal explant culture, the models more relevant to human, (2) evaluate the healing effect of galectin-3 in our models, and (3) determine if galectin-3 enhances cell adhesion by interacting with ECMs on corneal surface and their ligand integrins...

The use of soluble cardiac biomarkers such as N-terminal pro-brain natriuretic peptide (NT-proBNP) and troponin has revolutionized prognostication for patients with AL amyloidosis. Soluble ST2 (sST2) and galectin-3 have also been reported to have prognostic value in other cardiac patient populations. We identified 502 patients with AL amyloidosis, who provided a research sample and consent to review their medical records between 1/1/2006-12/31/2010 within 90 days of their diagnosis. Samples were assayed for sST2 and galectin-3...

Although most of Dr Scully's research addressed diseases of the ovary, about 10% of his published manuscripts focused on endometrial lesions, most often consisting of observations about unusual types or deceptive patterns of endometrial carcinoma that had not previously been described, or lesions for which the behavior had been unknown. He characterized and clarified the entity of clear cell carcinoma of the endometrium, and wrote about endometrial carcinomas with argyrophil, oxyphil, and giant cells, and those simulating microglandular hyperplasia of the cervix, as well as uterine papillary serous, squamous cell, and small cell carcinoma,...

Lymph node metastasis is recognized as an important mode of liver cancer metastasis. Our previous study has built two hepatocarcinoma cell lines, Hca-F with high (75%) and Hca-P with low (25%) incidences of lymph node metastasis, and has indicated that annexin A7 is an important factor in the lymphatic metastasis of tumors. There is evidence that galectin-3 is the binding protein of annexin A7 and works in protein complexes. Our current study shows that both annexin A7 and galectin-3 express higher in Hca-F than Hca-P...

There are few mouse models that adequately mimic large bowel cancer in humans or the gastrointestinal inflammation which frequently precedes it. Dextran sodium sulphate (DSS)-induces colitis in many animal models and has been used in combination with the carcinogen azoxymethane (AOM) to induce cancer in mice. Smad3(-/-) mice are deficient in the transforming growth factor beta (TGFβ) signaling molecule, SMAD3, resulting in dysregulation of the cellular pathway most commonly affected in human colorectal cancer, and develop inflammation-associated colon cancer...

INTRODUCTION: Oral epithelial dysplasia (OED) is a potentially malignant lesion characterized by a combination of cytological and architectural anomalies, which are essential for its diagnosis. Galectins are proteins that participate in cell cycle, adhesion and differentiation, apoptosis, and immune responses, as well as in cancer development and progression. MATERIALS AND METHODS: The aim of this study was to analyze the immunohistochemical expression of galectins-1, -3, and -7 in the OED (21 low risk and 29 high risk) and normal oral mucosa (NOM)...

The macrofollicular variant of papillary thyroid carcinoma (MFPTC) is a well-established entity with characteristic large follicles containing pale colloid and lined by cells with nuclear features of papillary thyroid carcinoma (PTC). In this study, we present three cases of MFPTC, along with a brief review of the literature. For all three of our cases, the histology of the resected specimen showed predominantly macrofollicular structures lined by cells with nuclear characteristics of PTC. Immunohistochemically, the three cases show positivity for galactin-3, cytokeratin-19, and HBME-1...

Systemic lupus erythematosus (SLE) is a prototypic systemic autoimmune diseases, which affects multiple organ systems such as kidney. The imbalance of T-helper 1 (Th1)/Th2 cells is critical in the pathogenesis of SLE. The T-cell immunoglobulin mucin (TIM) proteins comprise a family of cell surface molecules expressed on T cells that regulate Th1- and Th2-cell-mediated immunity. Recent work has found increased expression of TIM-1 and TIM-3 ligand (galactin-9) mRNA in SLE patients and implied that TIM proteins might be involved in the pathogenesis of SLE...

Very few of the genes that are important in pituitary tumor initiation, progression, and metastasis have been identified to date. To identify potential genes that may be important in pituitary tumor progression and carcinoma development, we used Affymetrix GeneChip HGU-133A-oligonucleotide arrays, which contain more than 15,000 characterized genes from the human genome to study gene expression in an ACTH pituitary carcinoma metastatic to the liver and four pituitary adenomas. Reverse-transcriptase real-time quantitative- PCR (RT-qPCR) was then used to analyze 4 nonneoplastic pituitaries, 19 adenomas, and the ACTH carcinoma...

Galactinol synthase catalyzes the first committed step in the biosynthesis of raffinose sugars. Previous attempts to purify the enzyme have proven difficult and have resulted in low quantities of unpurified enzyme. Galactinol synthase was purified 752-fold from mature zucchini (Cucurbita pepo L. cv Burpee Hybrid) leaves using sequential liquid chromatography on DE 52, Octyl-Sepharose CL-4B, and Sephacryl S-200. This isolation scheme resulted in an 18.6% recovery of the initial activity. The purified enzyme had a specific activity of 23...

Galectin-3 has been extensively studied as an immunohistochemical marker of thyroid malignancy, and a high diagnostic accuracy has been reported even for difficult pathological diagnoses, such as minimal invasive follicular carcinoma. We consequently hypothesized that the quantitative analysis of galectin-3 mRNA rather than the more observer-dependent immunohistological determination might enhance the diagnostic workup of ambiguous thyroid lesions. In the present study, we set out to validate this approach by analyzing concomitantly the expression and production of galectin-3 in benign and malignant thyroid tumors by means of quantitative PCR and immunohistochemistry...

Galectin-3 was detected immunohistochemically in nine canine gastric carcinomas. In normal gastric tissue adjacent to the neoplasms, the gastric epithelial cells showed faint immunolabelling for galectin-3, but in all the tumours the neoplastic cells showed moderate to strong immunolabelling. Galectin-3 was localized in the cytoplasm of the normal mucosal cells, whereas it was found in both the cytoplasm and the nucleus of the neoplastic cells. Positive cells typically exhibited dark brown coloration of the nucleus or cytoplasm, without background labelling...
