Morphogenetic and histogenetic roles of the temporal-spatial organization of cell proliferation in the vertebrate corticogenesis as revealed by inter-specific analyses of the optic tectum cortex development
(Frontiers Research Foundation, 2016-03)
The central nervous system areas displaying the highest structural and functional complexity correspond to the so called cortices, i.e. concentric alternating neuronal and fibrous layers. Corticogenesis, i.e. the development ...
HIF involvement in the regulation of rat Sertoli cell proliferation by FSH
(Academic Press Inc Elsevier Science, 2018-08)
The final number of Sertoli cells reached during the proliferative periods determines sperm production capacity in adulthood. It is well known that FSH increases the rate of proliferation of Sertoli cells; however, little ...
Metformin counteracts the effects of FSH on rat Sertoli cell proliferation
(BioScientifica, 2018-05)
Metformin (MET) is one of the most widely used anti-hyperglycemic agents for treating patients with type 2 diabetes and it has started to be used in pediatric population at ages when Sertoli cells are still proliferating. ...
Effect of lead on proliferation, oxidative stress and genotoxic damage of 3T3-L1 fibroblasts
(Oxford University Press, 2020-04)
Lead (Pb) is an environmental and industrial contaminant that still represents a public health problem. In this paper, we investigated the effect of Pb on proliferation, lipid peroxidation and the number of micronucleated ...
PLAGL1 gene function during hepatoma cells proliferation
(Impact Journals LLC, 2018-08-28)
Hepatocellular carcinoma develops as a multistep process, in which cell cycle deregulation is a central feature, resulting in unscheduled proliferation. The PLAGL1 gene encodes a homonym zinc finger protein that is involved ...
Effects of aromatase inhibitors on proliferation and apoptosis in eutopic endometrial cell cultures from patients with endometriosis
(American Society for Reproductive Medicine, 2005-08)
To study the effect of letrozole (Let) and anastrozole (Anas) on apoptosis and cell proliferation in epithelial endometrial cells (EEC) from patients with endometriosis (EDT). Prospective study. Eighteen women with untreated ...
Molecular mechanisms and signaling pathways involved in Sertoli cell proliferation
(Frontiers Media, 2019-04)
Sertoli cells are somatic cells present in seminiferous tubules which have essential roles in regulating spermatogenesis. Considering that each Sertoli cell is able to support a limited number of germ cells, the final ...
CXCL12 is a costimulator for CD4+ T cell activation and proliferation in chronic lymphocytic leukemia patients
(Springer, 2013-01)
Activated T cells from patients with chronic lymphocytic leukemia (CLL) provide survival and proliferative signals to the leukemic clone within lymphoid tissues. Recruitment of both, CLL cells and T lymphocytes, to this ...
Cellular and molecular basis associated with metacestode proliferation in subarachnoid neurocysticercosis
(Frontiers Media, 2022)
Taenia solium is a cestode parasite with a complex life cycle that includes two mammalian hosts: pigs and humans. Humans are the only definitive host, in whose small intestine develops and lives the adult form of the ...
Progestin activation of nongenomic pathways via cross talk of progesterone receptor with estrogen receptor beta induces proliferation of endometrial stromal cells
(Endocrine Society, 2005-12)
Uterine decidualization is characterized by stromal cell proliferation and differentiation, which are controlled by ovarian hormones estradiol and progesterone. Here we report that the proliferative response of UIII rat ...
