The role and implications of mammalian cellular circadian entrainment

open access: yesFEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Serum-Free Cryopreservation of Five Mammalian Cell Lines in Either a Pelleted or Suspended State

open access: yesBiological Procedures Online, 2004
Herein we have explored two practical aspects of cryopreserving cultured mammalian cells during routine laboratory maintenance. First, we have examined the possibility of using a serum-free, hence more affordable, cryopreservative.

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10

open access: yesFEBS Letters, EarlyView.
Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...

ASIC currents in cultured primate retinal amacrine/ganglion cells

open access: yesPhysiological Reports
Acid‐sensing ion channels (ASICs) are proton‐gated cation channels belonging to the epithelial Na + channel/degenerin superfamily. In the CNS, ASICs are involved in synaptic plasticity, learning/memory, and acidosis‐mediated injury.

Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

open access: yesFEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

Extraction and purification of tumorigenic Schwann cells in vitro from neurofibromatosis type 2 tissues

open access: yesChinese Journal of Contemporary Neurology and Neurosurgery, 2011
Objective To establish a simple method to extract and purify tumorigenic Schwann cells (TSCs) from neurofibromatosis type 2 (NF2) tumor tissues in vitro, in order to improve the successful rate of primary culture and obtain a large number of TSCs from ...

Real‐time assay of ribonucleotide reductase activity with a fluorescent RNA aptamer

open access: yesFEBS Letters, EarlyView.
Ribonucleotide reductases (RNR) synthesize DNA building blocks de novo, making them crucial in DNA replication and drug targeting. FLARE introduces the first single‐tube real‐time coupled RNR assay, which enables isothermal tracking of RNR activity at nanomolar enzyme levels and allows the reconstruction of allosteric regulatory patterns and rapid ...

Effects of light-curing time on the cytotoxicity of a restorative composite resin on odontoblast-like cells

open access: yesJournal of Applied Oral Science, 2010
This in vitro study evaluated the cytotoxicity of an experimental restorative composite resin subjected to different light-curing regimens. METHODS: Forty round-shaped specimens were prepared and randomly assigned to four experimental groups (n=10), as ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Experimental model for establishment of hypoxia in 75 cm² culture flasks Modelo experimental para o estabelecimento de hipóxia em balões de cultura de 75 cm²

open access: yesActa Cirúrgica Brasileira, 2004
In Plastic Surgery, cell culture represents the perspective of studying cellular mechanisms that guide the healing process of several tissues. Some steps of the healing process depend on physical factors as the tissular partial pressure of O2.
