Protective effect of Spirulina in the ovary of rats against Doxorubicin toxicity
Summary
This experimental study examined whether Spirulina supplementation could protect rat ovaries from toxicity caused by doxorubicin, an anti-cancer agent known to cause reproductive side effects. Spirulina's antioxidant phytopigments including beta-carotene and tocopherols were found to reduce Dox-induced reproductive toxicity in ovarian tissue.
Doxorubicin (Dox) is an anti–cancer agent used of ovarian, breast, liver, lung cancers and solid tumors such as leukemia and lymphoma treatment. However, since it is an antineoplastic agent with a high toxic effect, it causes toxicity on many organs and tissues in the organism. Spirulina spp. (SP) contains phytopigments such as β–carotene, tocopherols and xanthophylls and is a natural source of vitamin A as well as its anticarcinogenic effect. For these reasons, this study was planned to experimentally reveal the antioxidant and protective effects of SP on Dox–induced reproductive toxicity in female rats. In the study, histopathological evaluation was performed after Hematoxylin–Eosin staining in female rats with Dox toxicity. The distribution of GSK–3β for cell proliferation, HIF–1α for oxidative stress and VEGF for vascularization were evaluated. TUNEL staining was performed to determine apoptosis. It was determined that SP prevented tissue damage on the ovarian tissue of rats with Dox toxicity, and this positive effect was achieved through factors such as oxidative stress (HIF–1α), vascularization (VEGF) and inhibition of cell death (Apoptosis). It has been observed that SP treatment to be applied after chemotherapy is effective in protecting both the developing follicles and the primordial follicle pool.

The Possible Impact of Spirulina and Chlorella on some Hematological and Biochemical Aspects in Irradiated Rats
Researchers found that oral supplementation of Spirulina platensis or Chlorella vulgaris before and after whole-body gamma irradiation significantly attenuated radiation-induced decreases in red and white blood cell counts, hemoglobin, and platelets, and reduced liver enzyme elevation in male albino rats. The results suggest both microalgae may offer protective effects against radiation-induced hematological and organ damage.
Apigetrin ameliorates doxorubicin prompted testicular damage: biochemical, spermatological and histological based study
Researchers tested whether the flavonoid apigetrin could protect rat testicular tissue from damage caused by the chemotherapy drug doxorubicin. They found that doxorubicin caused significant oxidative stress, inflammation, hormone imbalance, and tissue damage in the testes, but co-administration of apigetrin substantially reduced these harmful effects. The study suggests that natural plant compounds may help protect reproductive health during cancer treatment.
Clinicopathological Studies on the Impact of Grape Seed Extract and L-Carnitine as Cardioprotective Agents Against Doxorubicin-Induced Toxicity in Rats
Researchers investigated whether grape seed extract and L-Carnitine could protect rat hearts from the toxic side effects of the cancer drug doxorubicin. Both supplements significantly reduced heart damage markers, lipid oxidation, and inflammation while improving antioxidant enzyme levels. The study suggests these natural compounds may offer protective benefits against drug-induced cardiac injury through their antioxidant and anti-inflammatory properties.
The mitigating effect of Spirulina (Arthrospira platensis) on the hemotoxicity of gibberellic acid on juvenile tilapia (Oreochromis niloticus)
Researchers investigated whether Spirulina algae supplementation could protect Nile tilapia fish from blood toxicity caused by gibberellic acid, a plant growth hormone widely used in agriculture that contaminates nearby waterways. Fish fed higher doses of Spirulina showed near-normal blood cell counts and reduced DNA damage after exposure, suggesting the algae has protective antioxidant properties that could help organisms cope with agricultural chemical contamination.
Overview of the evaluation of the destructive effect of procarbazine on the ovarian reserve in the apoptotic, inflammatory, and oxidative pathways
This review evaluated the evidence on procarbazine's toxic effects on ovarian function, examining both clinical data from cancer treatment and experimental findings on mechanisms of ovarian damage. The findings are relevant for fertility preservation in women receiving procarbazine-containing chemotherapy.
