Chromosomal aberrations as a cause of infertility: diagnosis and genetic counseling in Las Tunas

open access: yesRevista Electrónica Dr. Zoilo E. Marinello Vidaurreta, 2017
Background: infertility is a clinical problem with a significant social medical impact on the health of the couple. It is considered that 36 % of the genetic causes of infertility are caused by chromosomal aberrations.Objective: to describe the results ...

A polymer physics model of the interphase cell nucleus for radiobiological simulations

open access: yesScientific Reports
Advances in chromatin architectures achieved through super-resolution imaging and high-throughput chromosome conformation capture (Hi-C) techniques remain to be integrated into the modeling framework of radiobiology.

Single‐cell DNA methylation profiling: Technologies, computation, and applications in precision oncology

open access: yesMolecular Oncology, EarlyView.
Single‐cell DNA methylation (scDNAme) profiling maps epimutational clonal evolution, revealing mechanisms of malignancy and therapeutic resistance across diverse cancer types. By providing a high‐resolution landscape of intratumoral heterogeneity, these technologies empower precise patient stratification, guide the development of enhanced ...

COMPARISON BETWEEN TWO FISH TECHNIQUES IN THE IN VITRO STUDY OF CYTOGENETIC MARKERS FOR LOW-DOSE X-RAY EXPOSURE IN HUMAN PRIMARY FIBROBLASTS

open access: yesFrontiers in Genetics, 2013
This work is about the setup of an in vitro system to report low-dose of X-rays as measured as cytogenetic damage. Q- and m-FISH, for telomere length and chromosome instability analysis respectively, were compared to evaluate their sensitivity in the low-

Pharmacological chromatin remodeling enhances response to estrogen therapy in ER+ breast cancer

open access: yesMolecular Oncology, EarlyView.
Estrogen therapy elicits clinical benefit in ~ 30% of patients with endocrine‐resistant estrogen receptor (ER)‐positive breast cancer. Based on findings that ER transcriptional activation underlies response to estrogen therapy, we tested the effects of epigenetic dysregulation via pharmacological inhibition of histone deacetylases (HDACi).

Nonrandom chromosome abnormalities in cancer An overview

open access: yes, 2015
This chapter discusses neoplastic karyotypes. It emphasizes the difference between primary and secondary changes and address the questions of why, how, when, and where chromosome abnormalities arise; compare numerical and structural aberrations in terms ...

PANoptosis in the pathogenesis of myelodysplastic syndromes

open access: yesMolecular Oncology, EarlyView.
PANoptosis, a combination of three types of programmed cell death, is mediated by a large protein complex called a PANoptosome. In healthy bone marrow hematopoietic cells, PANoptosis is restricted by inhibitory signaling. In MDS, bone marrow cells become sensitive to the PANoptotic stimuli due to the aberrant inactivation of inhibitory signaling or ...

Cytomolecular identification of individual wheat-wheat chromosome arm associations in wheat-rye hybrids [PDF]

open access: yes, 2013
Chromosome pairing in the meiotic metaphase I of wheatrye hybrids has been characterized by sequential genomic and fluorescent in situ hybridization allowing not only the discrimination of wheat and rye chromosomes, but also the identification of the
