STUDY QUESTION Is pigment epithelium-derived factor (PEDF) expressed in the rodent endometrium and can it be utilized to treat endometriosis without negatively affecting reproductive parameters? SUMMARY ANSWER PEDF is dynamically expressed in rat endometrium throughout the estrous cycle in a reciprocal manner to vascular endothelial growth factor (VEGF); it possesses potent therapeutic proper...
D on timing and venue, new blood vessel growth can be either beneficial or pathological. Vigorous vessel growth is absolutely necessary for tissue, organ, and limb development as was graphically demonstrated a few decades ago with thalidomide, now known to be a compound with antiangiogenic properties. As one ages though, the need for angiogenesis decreases or stops entirely except for specializ...
Diabetic retinopathy (DR) is a major cause of blindness in working age adults, and oxidative stress plays a vital role in the pathogenesis of DR. Pigment-epithelium-derived factor (PEDF), a multifunctional protein, has shown to inhibit the development of DR by accumulating evidence. This paper highlights the current understanding of probable mechanism about how PEDF blocks the deterioration of ...
Recent studies have suggested that a novel adipokine, C1q/tumor necrosis factor-related protein-3 (CTRP-3), a paralog of adiponectin, may play an important role in the regulation of glucose metabolism and innate immunity. Pigment epithelium-derived factor (PEDF), a multifunctional protein with antioxidant and anti-inflammatory properties, is associated with insulin resistance and metabolic synd...
Pigment epithelium-derived factor (PEDF) was first identified in retinal pigment epithelium cells. It is an endogenously produced protein that is widely expressed throughout the human body such as in the eyes, liver, heart, and adipose tissue; it exhibits multiple and varied biological activities. PEDF is a multifunctional protein with antiangiogenic, antitumorigenic, antioxidant, anti-inflamma...
Male fertility depends on spermatogenesis, which takes place in the seminiferous tubules of the testis. This compartment is devoid of blood vessels, which are however found in the wall of the seminiferous tubules. Our proteomic study using cultured human testicular peritubular cells (HTPCs) i.e. the cells, which form this wall, revealed that they constitutively secrete pigment epithelium-derive...
Metastatic melanoma cells are highly adaptable to their in vivo microenvironment and can switch between protease-dependent mesenchymal and protease-independent amoeboid invasion to facilitate metastasis. Such adaptability can be visualized in vitro, when cells are cultured in conditions that recapitulate three-dimensional microenvironments. Using thick collagen layers in cell culture and in viv...
AIMS Mesenchymal stem cells (MSCs) can ameliorate myocardial infarction (MI) injury. However, older-donor MSCs seem less efficacious than those from younger donors, and the contributing underlying mechanisms remain unknown. Here, we determine how age-related expression of pigment epithelium-derived factor (PEDF) affects MSC therapeutic efficacy for MI. METHODS AND RESULTS Reverse transcriptas...
Clinical expansion of mesenchymal stem cells (MSCs) is hampered by the lack of knowledge regarding how to prevent MSC apoptosis and promote their proliferation in serum-free medium. Our in vitro studies demonstrated that human umbilical cord MSCs (HUCMSCs) underwent apoptosis in the serum-free medium. When HUCMSCs were co-cultured with retinal pigment epithelial cells (ARPE19), however, HUCMSCs...
Neuroblastoma is notable for its cellular heterogeneity and unpredictable outcome. Tumors are a variable mixture of primitive malignant neuroblasts, more differentiated ganglionic cells, Schwann and endothelial cells. Although often fatal, neuroblastomas can spontaneously regress, possibly due to favorable autocrine and paracrine interactions among these cells. Here, pigment epithelium-derived ...
