Developmental Dynamics, EarlyView.Abstract Background CD163 is a scavenger receptor predominantly expressed on the surfaces of macrophages in various mammalian species and is a marker of anti‐inflammatory (M2‐like) macrophages. High density of CD163‐positive tumor‐associated macrophages (TAMs) is associated with worse prognosis in various patient tumors.

Stochastic nonlinear model for somatic cell population dynamics during ovarian follicle activation [PDF]
arXiv, 2019 In mammals, female germ cells are sheltered within somatic structures called ovarian follicles, which remain in a quiescent state until they get activated, all along reproductive life. We investigate the sequence of somatic cell events occurring just after follicle activation, starting by the awakening of precursor somatic cells, and their ...

Control of ovarian primordial follicle activation [PDF]
Clinical and Experimental Reproductive Medicine, 2012 The ovarian follicles develop initially from primordial follicles. The majority of ovarian primordial follicles are maintained quiescently as a reserve for the reproductive life span. Only a few of them are activated and develop to an advanced follicular stage.

Regulation of reproduction via tight control of gonadotropin hormone levels. [PDF]
, 2018 Mammalian reproduction is controlled by the hypothalamic-pituitary-gonadal axis. GnRH from the hypothalamus regulates synthesis and secretion of gonadotropins, LH and FSH, which then control steroidogenesis and gametogenesis. In females, serum LH and FSH

Bitter Taste Receptor Agonists Induce Apoptosis in Papillary Thyroid Cancer
Head &Neck, EarlyView.ABSTRACT Background Papillary thyroid carcinoma (PTC) is the most common thyroid malignancy, with a 20% recurrence rate. Bitter taste receptors (T2Rs) and their genes (TAS2Rs) may regulate survival in solid tumors. This study examined T2R expression and function in PTC cells.

The spatiotemporal expression pattern of the bone morphogenetic protein family in rat ovary cell types during the estrous cycle. [PDF]
, 2003 In the mammalian ovary, great interest in the expression and function of the bone morphogenetic protein (BMP) family has been recently generated from evidence of their critical role in determining folliculogenesis and female fertility.

Head &Neck, EarlyView.ABSTRACT Background Data connecting PTEN mutations with thyroid cancer risk for indeterminate nodules remain limited due to the rare nature of these mutations. The aim of this study was to determine the relationship between PTEN mutations identified in cytologically indeterminate nodules and final pathology and clinical outcomes.

Action of the Metalloproteinases in Gonadal Remodeling during Sex Reversal in the Sequential Hermaphroditism of the Teleostei Fish Synbranchus marmoratus (Synbranchiformes: Synbranchidae) [PDF]
, 2018 Teleostei present great plasticity regarding sex change. During sex reversal, the whole gonadincluding the germinal epithelium undergoes significant changes, remodeling, and neoformation.However, there is no information on the changes that occur within ...

Epigenomics‐guided precision oncology: Chromatin variants in prostate tumor evolution
International Journal of Cancer, EarlyView.Abstract Prostate cancer is a common malignancy that in 5%–30% leads to treatment‐resistant and highly aggressive disease. Metastasis‐potential and treatment‐resistance is thought to rely on increased plasticity of the cancer cells—a mechanism whereby cancer cells alter their identity to adapt to changing environments or therapeutic pressures to create

Advances in methods for determining fecundity: application of the new methods to some marine fishes [PDF]
, 2009 Estimation of individual egg production (realized fecundity) is a key step either to understand the stock and recruit relationship or to carry out fisheries-independent assessment of spawning stock biomass using egg production methods.
