'Hypoxia plays a crucial role in many pathophysiological conditions, including cancer biology, and hypoxia-inducible factor (HIF) regulates transcriptional responses under hypoxia. To elucidate the cellular responses to hypoxia, we performed chromatin immunoprecipitation with deep sequencing in combination with microarray analysis and identified HIF-1 targets. We focused on one of the ... More
Optimization of gene delivery methods in Xenopus laevis kidney (A6) and Chinese hamster ovary (CHO) cell lines for heterologous expression of Xenopus inner ear genes.
'The Xenopus inner ear provides a useful model for studies of hearing and balance because it shares features with the mammalian inner ear, and because amphibians are capable of regenerating damaged mechanosensory hair cells. The structure and function of many proteins necessary for inner ear function have yet to be ... More
Gallic acid induces mitotic catastrophe and inhibits centrosomal clustering in HeLa cells.

Cancer cells divide rapidly, providing medical targets for anticancer agents. The polyphenolic gallic acid (GA) is known to be toxic for certain cancer cells. However, the cellular mode of action has not been elucidated. Therefore, the current study addressed a potential effect of GA on the mitosis of cancer cells. ... More
Hypermutator Salmonella Heidelberg induces an early cell death in epithelial cells.

PubMed ID26320605
We have previously described that a strain of Salmonella Heidelberg with a hypermutator phenotype, B182, adhered strongly to HeLa cells. In this work, we showed that this hypermutator Salmonella strain invaded HeLa epithelial cells and induced cytoskeleton alteration. Those changes lead to HeLa cell death which was characteristic of apoptosis. ... More
The Effect of Age on Osteogenic and Adipogenic Differentiation Potential of Human Adipose Derived Stromal Stem Cells (hASCs) and the Impact of Stress Factors in the Course of the Differentiation Process.

Human adipose tissue is a great source of autologous mesenchymal stem cells (hASCs), which are recognized for their vast therapeutic applications. Their ability to self-renew and differentiate into several lineages makes them a promising tool for cell-based therapies in different types of degenerative diseases. Thus it is crucial to evaluate ... More
MicroRNA and protein profiling of brain metastasis competent cell-derived exosomes.
AuthorsCamacho L, Guerrero P, Marchetti D,
Journal
PubMed ID24066071
Exosomes are small membrane vesicles released by most cell types including tumor cells. The intercellular exchange of proteins and genetic material via exosomes is a potentially effective approach for cell-to-cell communication and it may perform multiple functions aiding to tumor survival and metastasis. We investigated microRNA and protein profiles of ... More
Nucleocytoplasmic coagulation: an injury-induced aggregation event that disulfide crosslinks proteins and facilitates their removal by plasmin.

Cellular injury causes a myriad of processes that affect proteostasis. We describe nucleocytoplasmic coagulation (NCC), an intracellular disulfide-dependent protein crosslinking event occurring upon late-stage cell death that orchestrates the proteolytic removal of misfolded proteins. In vitro and in vivo models of neuronal injury show that NCC involves conversion of soluble intracellular proteins, ... More
Spreading of neurodegenerative pathology via neuron-to-neuron transmission of ß-amyloid.
Alzheimer's disease (AD) is the major cause of dementia. During the development of AD, neurofibrillary tangles progress in a fixed pattern, starting in the transentorhinal cortex followed by the hippocampus and cortical areas. In contrast, the deposition of ß-amyloid (Aß) plaques, which are the other histological hallmark of AD, does ... More

This paper describes the use of the baculovirus Autographa californica multiple nuclear polyhedrosis virus (AcMNPV) as a vector for gene delivery into mammalian cells. A modified AcMNPV virus was prepared that carried the Escherichia coli lacZ reporter gene under control of the Rous sarcoma virus promoter and mammalian RNA processing ... More

The recombinant baculovirus/insect cell system was firmly established as a leading method for recombinant protein production when a new potential use for these viruses was revealed in 1995. It was reported that engineered recombinant baculoviruses could deliver functional expression cassettes to mammalian cell types; a system which has come to ... More

'Currently, equine metabolic syndrome (EMS), an endocrine disease linked to insulin resistance, affects an increasing number of horses. However, little is known about the effect of EMS on mesenchymal stem cells that reside in adipose tissue (ASC). Thus it is crucial to evaluate the viability and growth kinetics of these ... More

'In this study, we investigated the role of adducts formation between aminochrome and tubulin and its interference in microtubules assembly and stability in aminochrome-induced toxicity in SH-SY5Y cells. We also investigated whether changes in the microtubules structures are an early event that could affect tubulin expression. We demonstrated in vitro ... More

Endothelial cells (ECs) line the interior of blood and lymphatic vessels and experience spatially varying wall shear stress (WSS) as an intrinsic part of their physiological function. How ECs, and mammalian cells generally, sense spatially varying WSS remains poorly understood, due in part to a lack of convenient tools for ... More
