Aims: The term ovarian carcinoma (OC) refers to a heterogeneous collection of five distinct diseases known as histotypes. While histotype-specific treatment is still a clinical challenge in OC, well-characterized models are required for testing new therapeutic strategies. We employed OncoTherad® (MRB-CFI-1), an interferon (IFN-γ)-stimulating nano-immunotherapy mediated by Toll-like receptors (TLR) 2/4, in association or not with Erythropoietin (EPO) in a chemically-induced ovarian cancer model.

Study Design: Experimental spinal cord lesion study.

Objectives: To evaluate the effects of erythropoietin at different doses on neural regeneration in rats undergoing spinal cord injury.

Methods: Anesthetized Wistar rats were submitted to standardized spinal cord injury and randomized into eight groups, receiving different magnitudes of trauma and single or repeated doses of intraperitoneal erythropoietin (500 or 5000 IU/kg of body weight).

Motor disorders are considered to originate mainly from brain lesions. Placental dysfunction or maternal exposure to a persistently hypoxic environment is a major cause of further motor disorders such as cerebral palsy. Our main goal was to determine the long-term effects of mild intrauterine acute ischemic stress on rat soleus myofibres and whether erythropoietin treatment could prevent these changes.

Article Synopsis
  • Erythropoietin (EPO) is a key growth factor that helps reduce cell death, manage oxidative stress, and promote new blood vessel formation (angiogenesis) in various tissues.
  • In a study using BALB/c mice, researchers compared the effects of EPO treatment versus no treatment and saline injection on brain angiogenesis.
  • The results showed that chronic treatment with recombinant human erythropoietin (rHuEPO) significantly increased the number of blood vessels in healthy mouse brains by 44%, indicating that lesions or low oxygen levels are not required for EPO's angiogenic effects.

Background: Recent studies have reported that helix B surface polypeptide (HBSP), an erythropoietin derivative, exhibits strong tissue protective effects, independent of erythropoietic effects, in a renal ischemia-reperfusion (IR) injury model. Meanwhile, the transforming growth factor-β (TGF-β) superfamily member glial cell line-derived neurotrophic factor (GDNF) demonstrated protective effect on podocytes . Using a rat puromycin aminonucleoside nephropathy (PAN) model, this study observed the renal protective effect of HBSP and investigated its renal protective effect on podocytes and mechanism related to GDNF.
