The regulatory role of Dicer in folliculogenesis in mice.

Study of Foeniculum vulgare Effect on Folliculogenesis in Female Mice

Effects of Morphine Dependency on the Ovarian Folliculogenesis Following Superovulation in Mice

Background: Opioids may affect hypothalamic GnRH secretion and Hypothalamic-Pituitary- Gonad axis, resulting in reproductive disturbances. Current study investigates the effects of morphine on structure of ovary following superovulalion through morphologic/morphometric studies. Methods: Twelve young female NMRI mice were allocated into treatment and control groups. Treatment group received oral...

Dicer-dependent microRNA pathway safeguards regulatory T cell function

Regulatory T (T reg) cells are indispensable for preventing autoimmunity. Incumbent to this role is the ability of T reg cells to exert their suppressor function under inflammatory conditions. We found that T reg cell-mediated tolerance is critically dependent on the Dicer-controlled microRNA (miRNA) pathway. Depletion of miRNA within the T reg cell lineage resulted in fatal autoimmunity indist...

Dicer Gene Expression as a Prognostic Factor in Acute Lymphoblastic Leukemia and Chronic Lymphocytic Leukemia in Fars Province

Alterations in the expression of microRNAs (miRNAs) have been proposed to play a role in the pathogenesis of acute lymphoblastic leukemia (ALL) and chronic lymphocytic leukemia (CLL). Dicer is one of the main regulators of miRNA biogenesis, and deregulation of its expression has been indicated as a possible cause of miRNA alterations observed in various cancers. Our aim was to analyze the expre...

Deletion of the RNaseIII Enzyme Dicer in Thyroid Follicular Cells Causes Hypothyroidism with Signs of Neoplastic Alterations

Micro-RNAs (miRNAs) are small non-coding RNAs that regulate gene expression, mainly at mRNA post-transcriptional level. Functional maturation of most miRNAs requires processing of the primary transcript by Dicer, an RNaseIII-type enzyme. To date, the importance of miRNA function for normal organogenesis has been demonstrated in several mouse models of tissue-specific Dicer inactivation. However...

P-119: Melatonin Protects Folliculogenesis through Up-Regulation of Estrogen Receptors in Mouse under Treatment with Nicotine

Background: Melatonin as the major hormone produced by the pineal gland has a significant role in mammalian reproduction. In this study the efficacy of melatonin coadministration with nicotine on mouse follicogenesis was investigated. Materials and Methods: A total of 32 Female adult NMRI mice were divided into four groups. The control group (n=8) received vehicle, group 2 (n=8) received nicoti...
