Expression of activin subunits and receptors in the developing human ovary:activin A promotes germ cell survival and proliferation before primordial follicle formation [PDF]

, 2004
The formation of the essential functional unit of the ovary, the primordial follicle, occurs during fetal life in humans. Factors regulating oogonial proliferation and interaction with somatic cells before primordial follicle formation are largely ...

Activins and Activin Receptors in Cell Growth

Experimental Biology and Medicine, 1997
Activin and inhibin, members of transforming growth factor-beta (TGFbeta) superfamily, have diverse and widespread effects within living organisms at many stages during growth and development. From the initial isolation of these growth factors based on their effects of FSH secretion, the study of these factors, as well as of the activin-binding protein

BMP15 regulates the inhibin/activin system independently of ovulation rate control in sheep [PDF]

, 2017
Polymorphisms in the gene encoding bone morphogenetic protein 15 (BMP15) have been associated with multiple ovulations in sheep. As BMP15 regulates inhibin expression in rodents, we assumed that the ovarian inhibin/activin system could mediate part of ...

Lutzomyia longipalpis TGF-β Has a Role in Leishmania infantum chagasi Survival in the Vector

Frontiers in Cellular and Infection Microbiology, 2019
Despite the increasing number of studies concerning insect immunity, Lutzomyia longipalpis immune responses in the presence of Leishmania infantum chagasi infection has not been widely investigated. The few available studies analyzed the role of the Toll

Activin regulates betaA-subunit and activin receptor messenger ribonuclic acid and cellular proliferation in activin-responsive testicular tumor cells [PDF]

, 1998
Activin, a member of the transforming growth factor-beta superfamily of growth and differentiation factors, has a number of actions in embryonic as well as adult tissues. These actions are mediated via a family of receptors containing two subtypes and at

Testis exposure to unopposed/elevated activin A in utero affects somatic and germ cells and alters steroid levels mimicking phthalate exposure

Frontiers in Endocrinology, 2023
Correct fetal testis development underpins adult male fertility, and TGFβ superfamily ligands control key aspects of this process. Transcripts encoding one such ligand, activin A, are upregulated in testes after sex determination and remain high until ...

Activin-A: active in inflammation in COPD [PDF]

European Respiratory Journal, 2014
Chronic obstructive pulmonary disease (COPD) is characterised by irreversible airflow limitation in which chronic inflammation of the airways plays a major role. The persistent inflammation is triggered by inhaled toxic substances, such as cigarette smoke.

Activin A as a Novel Chemokine Induces Migration of L929 Fibroblasts by ERK Signaling in Microfluidic Devices

Frontiers in Cell and Developmental Biology, 2021
Activin A, a member of the transforming growth factor-beta (TGF-β) superfamily, contributes to tissue healing and fibrosis. As the innate tissue cells, fibroblasts also play an important role in wound healing and fibrosis. Herein, this study was aimed to

Localization of Activin and Activin Receptors in Rat Spinal Motoneurons

Journal of Biomedical Science, 1996
The purpose of this experiment was to determine whether rat spinal motoneurons (a) produce activin protein and (b) transcribe mRNAs coding for the betaA-subunit of activin and activin receptors II and IIB. The production of activin was determined by immunocytochemistry.

Activin/follistatin system in grass carp pituitary cells: - Regulation by local release of growth hormone and luteinizing hormone and its functional role in growth hormone synthesis and secretion.

PLoS ONE, 2017
Gonadotrophin regulation by activin/follistatin system is well-documented, but the corresponding effect on growth hormone (GH) has not been fully characterized and with little information available in lower vertebrates, especially in fish models.
