Cyclins D1 and A2 are cell cycle regulators that also have the ability to interact with the estrogen receptor (ER) and consequently interfere with antiestrogen treatment in breast cancer. Experimental data support this concept, but the clinical relevance needs to be further established. In this study, we evaluated cyclin D1 and A2 protein expression by immunohistochemistry and cyclin D1 gene (C...
In vitro manipulation of hematopoietic stem cells (HSCs) is a key issue in both transplantation therapy and regenerative medicine, and thus new methods are required to achieve HSC expansion with self-renewal. GATA2 is a transcription factor controlling pool size of HSCs. Of interest, continuous overexpression of GATA2 does not induce HSC proliferation. In this report, we demonstrate that GATA2 ...
BACKGROUND Loss of cardiomyocytes after myocardial infarction (MI) causes heart failure. In this study, we investigate whether the in situ cardiomyocytes can re-enter the cell cycle and to what extent cell division of cardiomyocytes occurs after acute MI (AMI) in rats. METHODS Sprague Dawley (SD) rats were used in this study; the left anterior descending coronary artery was ligated. At time p...
Arginine is a non-essential amino acid that modulates nitric oxide production and cancer homeostasis. In our previous study, we observed that blocking argininosuccinate lyase (ASL) attenuates tumor progression in liver cancer. However, the role of ASL in human breast cancer has been studied to a lesser degree. In the present study, we investigated the effect of targeting ASL in breast cancer. W...
Arginine biosynthesis and nitric oxide (NO) production are important for cancer homeostasis. Degradation of arginine may be used to inhibit liver tumors with low argininosuccinate synthetase (ASS) expression. In this report, we investigated an alternative therapeutic approach by targeting argininosuccinate lyase (ASL). ASL is transcriptionally induced by endoplasmic reticulum stress and is over...
17β-Estradiol (E2) is a multifunctional steroid hormone in modulating metabolism in vivo. Previous studies have reported that E2 could promote insulin secretion and protect β cells from apoptosis. In this study, the partial pancreatectomy (PPx) model was used to study the role of E2 in islet cell proliferation. The animals were divided into four groups, including sham control, PPx model, E2, an...
Gastric cancer is one of the most common cancers globally with high rates of morbidity and mortality. Purified Omphalia lapidescens protein (pPeOp) is a protein extracted from the sclerotium of Omphalia lapidescens. The present study aimed to investigate the effects of pPeOp on the viability, migration, cell cycle progression and apoptosis of SGC-7901 cells. The expression of numerous proteins,...
Kaposi's sarcoma (KS) is common in Africa, but economic constraints hinder successful treatment in most patients. Propranolol, a generic β-adrenergic antagonist, decreased proliferation of KS-associated herpesvirus (KSHV)-infected cells. Downregulation of cyclin A2 and cyclin-dependent kinase 1 (CDK1) recapitulated this phenotype. Additionally, propranolol induced lytic gene expression in assoc...
