The role of monocarboxylate transpoter 1 to uptake acetate in low glycolytic hepatocellular carcinoma cell line HepG2 cells
Conclusions Our data demonstrate that acetate was supported to HCC cells through MCT1 specifically in the low glycolytic cancer cells, and high MCT1 expression is related with low glycolytic phenotype cancer that would be the therapeutic target or diagnosis probe for low glycolytic cancers.

Tpl2 inhibitors thwart endothelial cell function in angiogenesis and peritoneal dissemination.
Abstract Angiogenesis is critical in the development of cancer, which involves several angiogenic factors in its peritoneal dissemination. The role of protein tumor progression locus 2 (Tpl2) in angiogenic factor-related endothelial cell angiogenesis is still unclear. To understand the precise mechanism(s) of Tpl2 inhibition in endothelial cells, this study investigated the role of Tpl2 in mediating angiogenic signals using in vitro, in vivo, and ex vivo models. Results showed that inhibition of Tpl2 inhibitor significantly reduced peritoneal dissemination in a mouse model by positron emission tomography/computed ...

Nitrilase 1 modulates lung tumor progression in vitro and in vivo.
In this study we aimed to determine the role of Nit1 in a transgenic mouse lung cancer model driven by a G12D Kras mutation. Nit1 knockout mice (Nit1-/-) were crossed with KrasG12D/+ mice to investigate whether a G12D Kras mutation and Nit1 inactivation interact to promote or inhibit the development of NSCLC. We found that lung tumorigenesis was suppressed in the Nit1-null background (Nit1-/-:KrasG12D/+). Micro-CT scans and gross tumor measurements demonstrated a 5-fold reduction in total tumor volumes compared to Nit1+/+KrasG12D/+ (p<0.01). Furthermore, we found that Nit1 is highly expressed in human lung cancer tissue...

Regulation of Acetate Utilization By Monocarboxylate Transporter 1 (MCT1) in Hepatocellular Carcinoma (HCC).
Authors: Jeon J, Lee M, Whang S, Kim JW, Cho A, Yun M Abstract Altered energy metabolism is a biochemical fingerprint of cancer cells. Hepatocellular carcinoma (HCC) shows reciprocal18F-Fluorodeoxyglucose (FDG) and 11C-acetate uptake, as revealed by positron emission tomography/computed tomography (PET/CT). Previous studies have focused on the role of FDG uptake in cancer cells; in this study, we evaluated the mechanism and roles of 11C-acetate uptake in human HCCs and cell lines. The expression of monocarboxylate transporters (MCTs) was assessed to determine the transporters of 11C-acetate uptake in HCC cell lines...

Metformin Promotes 2-Deoxy-2- 18 FFluoro-D-Glucose Uptake in Hepatocellular Carcinoma Cells Through FoxO1-Mediated Downregulation of Glucose-6-Phosphatase
ConclusionsWe propose that treatment of HCC cells with Met may be a useful strategy for improving the efficacy of [18F]FDG as a tracer for PET/CT imaging of HCC tumors in patients.

Ghrelin protects against depleted uranium-induced bone damage by increasing osteoprotegerin/RANKL ratio.
Abstract Depleted uranium (DU) is widely used in military and civil activities, and bone is the main target organ of chronic DU toxicity. The aim of this study was to evaluate the effects of ghrelin on rats implanted with DU and explore the underlying mechanisms. The results showed that ghrelin could increase the expression of ghrelin receptor in bone tissue, thus alleviate the apoptosis of bone tissue after 3 months of 0.3 g DU embedded in the tibia. Micro-computed tomography examination showed that after DU implantation, the density of cortical bone showed no significant difference, but the trabecular bone d...

Inositol trisphosphate receptor type 3-mediated enhancement of EGFR and MET co-targeting efficacy in non-small cell lung cancer detected by 18F-fluorothymidine.
CONCLUSIONS: Our findings indicate that 18F-FLT PET/CT is able to detect the enhanced efficacy of EGFR and MET inhibitors in oncogene-driven NSCLC and that such enhancement is mediated by IP3R3 through its interaction with K-Ras. PMID: 29618618 [PubMed - as supplied by publisher]

Age-dependent expression of the Vitamin D receptor and the protective effect of Vitamin D receptor activation on H2O2-induced apoptosis in rat intervertebral disc cells
Publication date: Available online 21 March 2019Source: The Journal of Steroid Biochemistry and Molecular BiologyAuthor(s): Tong Tong, Zhihui Liu, Hua Zhang, Jinglei Sun, Dongxia Zhang, Feng Wang, Dechao Miao, Yong ShenAbstractAccumulating evidence shows that genetic polymorphism of the vitamin D receptor (VDR) gene is associated with intervertebral disc degeneration (IDD), implying that VDR may be involved in the pathogenesis of IDD. However, the exact relationship between VDR and IDD remains unknown. The aim of this study was to investigate the age-dependent expression of VDR in rat intervertebral discs and to determine ...

Ability to Suppress TGF- β-Activated Myofibroblast Differentiation Distinguishes the Anti-pulmonary Fibrosis Efficacy of Two Danshen-Containing Chinese Herbal Medicine Prescriptions
Conclusion: This study suggests that a clinically efficacious cardiovascular Chinese herbal medicine (DLP) can be successfully repurposed to treat a lung disease in pulmonary fibrosis guided by TCM theory. Our comparative study between DLP and DHP demonstrated a critical requirement of suppressing both pro-inflammatory and pro-fibrotic pathways for the treatment of pulmonary fibrosis, supporting that a multi-component prescription capable of “removing both phlegm and blood stasis” will better achieve co-protection of heart and lung in PHD. Introduction Idiopathic pulmonary fibrosis (IPF) is a chronic ...

Tracking adiponectin biodistribution via fluorescence molecular tomography indicates increased vascular permeability after streptozotocin-induced diabetes.
Abstract Adiponectin, highly abundant in plasma, plays an important role in mediating important beneficial effects in diabetes, inflammation and cardiovascular disease. To act on target tissues, adiponectin must move from circulation to the interstitial space, suggesting that vascular permeability plays an important role in regulating adiponectin action. To test this hypothesis, fluorescently-labelled adiponectin was used to monitor its biodistribution in mice with streptozotocin-induced diabetes (STZD). Adiponectin was indeed found to have increased sequestration in the highly fenestrated liver and other tissues ...
