BACKGROUND Substantially elevated blood D-lactate (DLA) concentrations are associated with neurocardiac toxicity in humans and animals. The neurological symptoms are similar to inherited or acquired abnormalities of pyruvate metabolism. We hypothesized that DLA interferes with mitochondrial utilization of L-lactate and pyruvate in brain and heart. METHODS(More)
Sphingosine-1-phosphate (S1P) is an important regulator of cancer development and progression. Its cellular concentration is controlled predominantly by sphingosine kinase (SK) and sphingosine-1-phosphate lyase (SPL). In the current study we showed that mRNA expressions for both SK and SPL were up-regulated throughout all four disease stages in human breast(More)
Hedyotis diffusa is a Chinese herbal medicine widely used in combination with other herbal medicines such as Scutellaria barbata to treat various types of cancer. Late-stage and recurrent cancer patients usually use H. diffusa during chemotherapy in expecting to achieve additive or synergistic therapeutic effects. Several classes of active ingredients,(More)
This study was performed to compare the effects of creatine supplementation (CR) before vs. after supervised resistance training (RT) in healthy older adults. Participants were randomized to one of two groups: CR-Before (0.1g•kg(-1) creatine before + 0.1g•kg(-1) placebo [rice flour] after RT, n = 11) or CR-After (placebo before + creatine after RT, n = 11).(More)
Sudden death syndrome (SDS) in fast growing broiler chickens has been recognized as a patho-physiological entity for four decades, but its pathogenesis still remains unknown. More recent investigations provided evidence that link SDS to cardiac arrhythmia, but the mechanism triggering arrhythmogenesis and factors responsible for fatal outcome are poorly(More)
Our study investigated the potential for important in vivo drug-nutrient transport interactions at the lactating mammary gland using the L-carnitine transporter substrates, cefepime and L-carnitine, as proof-of-concept. On d 4 (n = 6/treatment) and d 10 (n = 6/treatment) of lactation, rats were administered cefepime (250 mg/h) or saline by continuous i.v.(More)
Glucose, fatty acids, and L-carnitine are important substrates that support mammary epithelial cell metabolism, biosynthetic capacity, and milk yield and composition. Our study investigated the effects of LPS-induced inflammation on the expression of several glucose, fatty acid, and L-carnitine transporters in the lactating rat mammary gland at different(More)
Human tumor suppressor gene RIZ encodes two protein products, tumor suppressor RIZ1 and proto-oncoprotein RIZ2, which regulate cellular functions in a Yin-Yang fashion. The only structural difference between them is that RIZ2 lacks the N-terminal PR domain. In this study, we showed that RIZ1 mRNA expression level was elevated in stage IV of eight different(More)
Sphingosine-1-phosphate (S1P) is an important sphingolipid metabolite regulating key physiological and pathophysiological processes such as cell growth and survival and tumor angiogenesis. Significant research evidence links elevated cellular S1P concentration to cancer cell proliferation, migration and angiogenesis. Physiological levels of S1P are tightly(More)
The present study examined the possible role of reactive oxygen species in the pathogenesis of heart failure in broilers. Data were collected from three groups of birds at various risk of heart failure: Leghorn chickens (resistant to heart failure), slow-growing feed-restricted broilers (low risk of heart failure), fast-growing ad libitum fed broilers (high(More)
