PATIENT-DERIVED XENOGRAFTS AS A PRECLINICAL MODEL FOR BONE SARCOMAS [PDF]

Acta Ortopédica Brasileira, 2018
Objective: The purpose of this study was to reproduce a mouse model of bone sarcomas for use in cancer research. Methods: A fresh sample of the tumor tissue was implanted subcutaneously into nude mice.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Germline Mutation in KIF1Bβ Gene Associated with Loss of Heterozygosity: Usefulness of Next-Generation Sequencing in the Genetic Screening of Patients with Pheochromocytoma

International Journal of Endocrinology, 2020
The genetic approach of pheochromocytomas and paragangliomas has changed in the last two decades. Nowadays, we know that more than 40% of patients have a germline mutation in one of the susceptibility genes identified to date. Our aim is to underline how

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Effect of colostomy on experimentally produced neoplasms of the colon of the rat [PDF]

Cancer, 1967
As a means of determining the effect of the fecal stream in the pathogenesis of experimentally produced colonic tumors in Wistar strain rats, simple colostomies were performed in the left colon of 57 female rats at approximately 4 cm above the anus. Fifty-four rats received daily subcutaneous injections, 5 days per week, of the carcinogen 3:2'dimethyl ...

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

FEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Molecular characterization of PH-negative myeloproliferative neoplasms in Ukraine

, 2013
Aim: The aim of this study was to examine the JAK2 V617F, the G1691A allele of factor V, and the G20210A prothrombin gene mutation status, and their predictive value for thrombosis in patients with Ph-negative myeloproliferative neoplasms (MPN) in ...

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

Molecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

Mature B-CELL neoplasms in Chernobyl clean-up workers of 1986–1987: summary of cytomorphological and immunocytochemical study in 25 years after Chernobyl accident

, 2011
The data on the verified cases of mature B-cell neoplasms (chronic lymphocytic leukemia – CLL, B-prolymphocytic leukemia, non-Hodgkin’s lymphoma in leukemization phase and multiple myeloma – MM; 146 cases in total) in the consecutive group of Ukrainian ...

Experimentally Produced Neoplasms in the Frog.

Experimental Biology and Medicine, 1930
It has been known that the frog egg on the stage of the second polar spindle-metaphase passes into a resting period, awaiting fertilization. Under natural conditions this lasts for only a few hours, but can be delayed up to 3 days without impairing perceptibly the vigor of the egg. After a further delay of 2 days, however, the eggs are dead.
