Murine models based on acute myeloid leukemia-initiating stem cells xenografting

World Journal of Stem Cells 2018年第6期10卷 57-65页

作者： cristina Mambet Mihaela Chivu-Economescu Lilia Matei Laura Georgiana Necula Denisa Laura Dragu Coralia Bleotu Carmen cristina diaconu Cellular and Molecular Pathology Department Stefan S. Nicolau Institute of Virology Nicolae Cajal Institute Titu Maiorescu University

Acute myeloid leukemia(AML) is an aggressive malignant disease defined by abnormal expansion of myeloid blasts. Despite recent advances in understanding AML pathogenesis and identifying their molecular subtypes based on somatic mutations, AML is still characterized by poor outcomes, with a 5-year survival rate of only 30%-40%, the majority of the patients dying due to AML relapse. Leukemia stem cells(LSC) are considered to be at the root of chemotherapeutic resistance and AML relapse. Although numerous studies have tried to better characterize LSCs in terms of surface and molecular markers, a specific marker of LSC has not been found, and still the most universally accepted phenotypic signature remains the surface antigens CD34+CD38- that is shared with normal hematopoietic stem cells. Animal models provides the means to investigate the factors responsible for leukemic transformation, the intrinsic differences between secondary post-myeloproliferative neoplasm AML and de novo AML, especially the signaling pathways involved in inflammation and hematopoiesis. However, AML proved to be one of the hematological malignancies that is difficult to engraft even in the most immunodeficient mice strains, and numerous ongoing attempts are focused to develop "humanized mice" that can support the engraftment of LSC. This present review is aiming to in-troduce the field of AML pathogenesis and the concept of LSC, to present the current knowledge on leukemic blasts surface markers and recent attempts to develop best AML animal models.

Recent advances in gastric cancer early diagnosis

World Journal of Gastroenterology 2019年第17期25卷 2029-2044页

作者： Laura Necula Lilia Matei Denisa Dragu Ana I Neagu cristina Mambet Saviana Nedeianu Coralia Bleotu Carmen C diaconu Mihaela Chivu-Economescu Department of Cellular and Molecular Pathology Stefan S.Nicolau Institute of Virology Faculty of Medicine Titu Maiorescu University

Gastric cancer(GC) remains an important cause of cancer death worldwide with a high mortality rate due to the fact that the majority of GC cases are diagnosed at an advanced stage when the prognosis is poor and the treatment options are limited. Unfortunately, the existing circulating biomarkers for GC diagnosis and prognosis display low sensitivity and specificity and the GC diagnosis is based only on the invasive procedures such as upper digestive endoscopy. There is a huge need for less invasive or non-invasive tests but also highly specific biomarkers in case of GC. Body fluids such as peripheral blood, urine or saliva,stomach wash/gastric juice could be a source of specific biomarkers, providing important data for screening and diagnosis in GC. This review summarized the recently discovered circulating molecules such as microRNAs, long non-coding RNAs, circular RNAs, which hold the promise to develop new strategies for early diagnosis of GC.
