Abstract
Cancer anemia, which is known as the malignant anemia associated with cancer, is one of the clinical symptoms of cancer and occurs in about half of cancer patients. Malignant tumor anemia is a common complication in various malignant tumors. In this anemia, the destruction of red blood cells leads to a decrease in access of tissues to oxygen leading to a reduced sensitivity of tumors to treatments such as radiotherapy and chemotherapy, and thus reduced quality of life in patients, reduced survival time and impact on the cancer prognosis. So, that the mortality rate in patients with anemia is two times higher than the patients without anemia during three years after diagnosis of cancer. Despite the fact that some studies have found that erythropoietin may improve symptoms of cancer-related anemia, this issue is still controversial in scientific literature and sessions.

Summary
Our previous study showed that Urena lobata L. hairy root is a potential pharmaceutical source for type 2 diabetes treatment. In order to improve the transformation efficacy and the quality of hairy roots, this study examined the effects of several factors including age, parts of plants, infection time and culture medium in inducing hairy roots in Urena lobata L. Methods: In this study, we investigated four factors to improve the hairy root induction in Urena lobata L These factors include: age of plant (15-day-old in vitro plants, 45-day-old in vitro plants and after two subculture generations plants), different parts of plant (roots, stems, and leaves), infection time (10, 20 and 30 minutes), and culture medium (Murashige and Skoog (MS), Gamborg B5 medium (GB5) and Woody plant medium (WPM)). Results: The results showed that the optimized procedure which used 15-day-old in vitro plants, the leafy part, the infection time of 10 minutes and culture in the WPM medium was better than the original procedure. After optimizing culturing parameters (medium composition, elicitor, precursor), hairy roots can be optimized to grow rapidly and produce valuable compounds 9
