Liver injury occurs frequently during sepsis. Pterostilbene (Pte), a natural dimethylated analog of resveratrol from blueberries, exerts anti-inflammatory and anti-apoptotic effects in various diseases. However, the role of Pte in sepsis-induced liver injury and its underlying mechanisms remain unknown. The current study aimed to evaluate the protective effects of Pte on sepsis-induced liver injury and its potential mechanisms. Sepsis was induced using cecal ligation and puncture (CLP) in C57BL/6 mice. Mice were administered Pte (5, 10, 15mg/kg, i...

MicroRNAs play an important role in regulating gene expression by binding to the 3' UTR of target mRNAs. In this studywe have made an attempt to assess the molecular mechanisms by which miR-32 suppresses the expression of SRCIN1, thereby leading to promotion of proliferation and epithelial-mesenchymal transition of human liver cancer cells. Human liver cancer cell lines HepG2 were transfected with miR-32 mimics and its control. The HepG2 cell lines were the assessed for miR-32 expression. The transfected cell lines were then studied for SRCIN1 expression by luciferase assay, effect of transfection on cell proliferation and finally epithelial-mesenchymal transition...

Id1 promotes carcinogenesis and metastasis, and predicts prognosis of non-small cell lung cancer (NSCLC)-adenocarcionoma patients. We hypothesized that Id1 may play a critical role in lung cancer colonization of the liver by affecting both tumor cells and the microenvironment. Depleted levels of Id1 in LLC (Lewis lung carcinoma cells, LLC shId1) significantly reduced cell proliferation and migration in vitro. Genetic loss of Id1 in the host tissue (Id1(-/-) mice) impaired liver colonization and increased survival of Id1(-/-) animals...

BACKGROUND: Parenchyma-sparing hepatectomy techniques allow a lesser volume resection (<3 adjacent segments) for tumors involving the hepatic veins at the hepatocaval confluence, assuring adequate volume of the future liver remnant. We report the ability to perform parenchyma-sparing hepatectomy as planned from the preoperative imaging and the type of vascular intervention used to preserve hepatic outflow. METHODS: We analyzed 60 consecutive parenchyma-sparing hepatectomies in 54 patients for 7 primary and 53 metastatic tumors (48 colorectal), located in segments I, VII, VIII, or IVa and involving the hepatocaval confluence...

BACKGROUND: Current evidence indicates that miR-608 is widely down-regulated in various malignant tumors including liver cancer, colon cancer, lung cancer and glioma, and acts as a tumor suppressor by inhibiting cell proliferation, invasion and migration or by promoting apoptosis. The specific biological function of miR-608 in bladder cancer is still unknown. METHODS: qRT-PCR and Chromogenic in Situ Hybridization (CISH) was conducted to assess the expression of miR-608 in paired BCa tissues and adjacent non-tumor bladder urothelial tissues...

OBJECTIVE: To determine the impact of RAS mutation status on the traditional clinical score (t-CS) to predict survival after resection of colorectal liver metastases (CLM). BACKGROUND: The t-CS relies on the following factors: primary tumor nodal status, disease-free interval, number and size of CLM, and carcinoembryonic antigen level. We hypothesized that the addition of RAS mutation status could create a modified clinical score (m-CS) that would outperform the t-CS...

For patients with advanced hepatocellular carcinoma (HCC), sorafenib is the only systemic treatment recommended by international guidelines. We recently reported that HCC patients with a low MoRAL (model to predict tumor recurrence after LDLT) score (≤ 314.8) have excellent treatment outcomes after living-donor liver transplantation (LDLT), even though they are beyond the Milan criteria. In the present study, we investigated whether LDLT offers a better treatment outcome than sorafenib for patients with HCC beyond the Milan criteria according to the MoRAL score...

Hepatitis B virus capsid (HBVC), a self-assembled protein nanoparticle comprised of 180 or 240 subunit proteins, is used as a cage for genetic encapsulation of fluorescent proteins (FPs). The self-quenching of FPs is controlled by varying the spacing between FPs within the capsid structure. Double-layered FP nanoparticle possessing cancer cell-targeting capabilities is also produced by additionally attaching FPs and cancer cell receptor-binding peptides (affibodies) to the outer surface of the capsid. The generically modified HBVC with double layers of mCardinal FPs and affibodies (mC-DL-HBVC) exhibit a high fluorescence intensity and a strong photostability, and is efficiently internalized by cancer cells and significantly stable against intracellular degradation...

Metastasis is a complex biological process that has been difficult to delineate in human colorectal (CRC) cancer patients. A major obstacle in understanding metastatic lineages is the extensive intratumor heterogeneity at the primary and metastatic tumor sites. To address this problem, we developed a highly-multiplexed single cell DNA sequencing approach to trace the metastatic lineages of two CRC patients with matched liver metastases. Single cell copy number or mutational profiling was performed, in addition to bulk exome and targeted deep-sequencing...

We investigated a new method for combining microbubble-enhanced ultrasound cavitation (MEUC) with hemocoagulase (HC) atrox. Our goal was to induce embolic effects in the vasculature and combine these with an anti-angiogenic treatment strategy. Fourteen days after being implanted with a single slice of the liver VX2 tumor, rabbits were randomly divided into five groups: (i) a control group injected intra-venously with saline using a micropump; (ii) a group given only an injection of HC; (iii) a group treated only with ultrasound cavitation; (iv) a group treated with MEUC; (v) a group treated with MEUC + HC...

Hepatocellular carcinoma (HCC) is a cause of several deaths related to cancer worldwidely. In early stage, curative treatments such as surgical resection, liver transplant and local ablation can improve the patient ´s survival. However, the disease is detected in advanced stage; moreover some available therapies are restricted to palliative care and local treatment. Early detections of HCC and adequate therapy are crucial to increase survival as well as to improve the patient´s quality of life. Therefore, researchers have been investigating molecular biomarkers with high sensibility and reliability as Golgi 73 protein (GP73), Glypican-3 (GPC3), Osteopontin (OPN), microRNAs and others...

Targeted delivery of chemotherapeutic drug at the tumor site enhances the efficacy with minimum systemic exposure. Towards this drugs conjugated with peptides having affinity towards a particular molecular target are recognized as affective agents for targeted chemotherapy. Thus in the present study tumor homing NGR peptide ligand was conjugated to DNA alkylating nitrogen mustard, chlorambucil (CLB). The peptide drug conjugate (PDC), CLB-c(NGR) was radiolabeled with (99m) Tc-HYNIC core to trace its pharmacokinetics and biodistribution pattern...
