In Vivo Chromatin Structure of the Murine Interleukin-5 Gene Region: A New Intact Cell System
BioTechniques, 1996 The study of chromatin involvement in the regulation of gene expression has traditionally required the isolation of nuclei. However, cell fractionation techniques are subject to redistribution of proteins during the isolation procedure, which prevents ...

Lysosomal membrane permeabilization in cell death [PDF]
Oncogene, 2008 Mitochondrial outer membrane permeabilization (MOMP) constitutes one of the major checkpoint(s) of apoptotic and necrotic cell death. Recently, the permeabilization of yet another organelle, the lysosome, has been shown to initiate a cell death pathway, in specific circumstances.

Carbachol increases intracellular free calcium concentrations in human granulosa-lutein cells [PDF]
, 1992 We investigated whether the stimulation of human granulosa-lutein cells with muscarinic and nicotinic receptor agonists can cause increases in intracellular free calcium (Ca2+), using Fura-2 microfluorimetry.

Concerted action of human chorionic gonadotropin and norepinephrine on intracellular-free calcium in human granulosa-lutein cells [PDF]
, 1993 Luteal cells are known to possess receptors for LH/hCG and receptors of the beta-adrenergic type. Interactions of specific agonists with either receptor lead to the activation of adenylate cyclase and subsequently to an increase of cAMP.

, 2021 In response to various pathological stimuli, such as oxidative and energy stress accompanied by high Ca2+, mitochondria undergo permeability transition (PT) leading to the opening of the non-selective PT pores (PTP) in the inner mitochondrial membrane ...

Permeabilization of lymphocytes with polyethylene glycol 1000. Discrimination of permeabilized cells by flow cytometry [PDF]
Cytometry, 1982 AbstractThe toxicity of polyethylene glycol 1000 (PEG) used similarly as in cell hybridization experiments, has been studied by flow cytometry, measuring the light scattering and fluorescence distributions of PEG‐treated human lymphocytes stained with propidium iodide, fluorescein diacetate and acridine orange (AO).

Bio-Protocol, 2020 Stress granules (SGs) are membrane-less organelles that form in the cytoplasm through phase separation, in response to diverse stressors. SGs contain translationally stalled mRNAs, proteins involved in translation, and various RNA-binding proteins (RBPs).

Guanylate cyclase activity in permeabilized Dictyostelium discoideum cells [PDF]
, 1996 Dictyostelium discoideum cells respond to chemoattractants by transient activation of guanylate cyclase. Cyclic GMP is a second messenger that transduces the chemotactic signal. We used an electropermeabilized cell system to investigate the regulation of
