    Author : Nataša Pavlović; Femke Heindryckx; Jessica Maiers; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hepatocellular carcinoma; fibrosis; endoplasmic reticulum stress; unfolded protein response; platelets; P2Y12; Molekylär cellbiologi; Molecular Cellbiology; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Abstract : Hepatocellular carcinoma (HCC), a highly deadly primary liver cancer with a rising global incidence and limited therapeutic options, is characterized by a vicious cross-talk between the tumor and its surrounding hepatic stroma. The stromal environment, consisting of hepatic stellate cells (HSC), endothelial cells, resident and infiltrating macrophages and other immune cells, platelets and extracellular matrix (ECM) components, actively contributes to creating an ideal niche for tumor proliferation and invasiveness.

  2. 2. The role of Lhx2 in the hematopoietic stem cell function, liver development and disease

    Author : Ewa Wandzioch; Leif Carlsson; Stephen A Duncan; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; liver fibrosis; liver development; Lhx2; hematopoietic stem cells; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi; molecular cell biology; molekylär cellbiologi;

    Abstract : During embryonic development, generation of functional organs is dependent on proper interactions between different cell types. Elucidation of the mechanisms operating during organ formation might provide insights into the origin of many pathological disorders in the adult. READ MORE

    Abstract : Experimental models with specific approaches to augment human fetal liver cell engraftment Pradeep Patil Department of Surgery, Institute of Clinical Sciences, Sahlgrenska Academy at University of Gothenburg Background: Liver disease is a common cause of morbidity and mortality worldwide. Orthotopic liver transplantation has so far been the only available therapy for patients with end-stage liver failure. READ MORE

  4. 4. Effects of 2,3,7,8-tetrachlorodibenzo-p-dioxin on vitamin A storage in rat hepatic stellate cells

    Keywords : Dioxin; TCDD; vitamin A; retinoids; lecithin:retinol acyltransferase; absorption; stellate celL hepatic vitamin A accumulation; intestinal lymph collectionDoctoral Thesis 1996 Annika Hanberg;

    Abstract : The polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs), popularly called dioxins, are persistent pollutants with widespread occurrence in the environment as well as in human food and tissues. 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD), the most toxic dioxin, as well as other dioxin-like compounds induce a broad spectrum of biochemical and toxic effects, many of which occur at extremely low doses or concentrations.

  5. 5. The Role of Lhx2 During Organogenesis : - Analysis of the Hepatic, Hematopoietic and Olfactory Systems

    Author : Åsa Kolterud; Leif Carlsson; Stefan Thor; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; LIM-homeobox gene; Lhx2; fetal liver; hepatic stellate cells; hematopoietic stem cells; septum transversum; self-renewal; odorant receptor genes; olfactory epithelium; olfactory sensory neuron; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; molekylärbiologi; Molecular Biology;

    Abstract : During embryonic development a variety of tissues and organs such as the lung, eye, and kidney are being formed. The generation of functional organs is regulated by reciprocal cell-cell interactions. Via the secretion of soluble molecules one type of cells affect the fate of their neighboring cells. READ MORE
