A comprehensive view on the quercetin impact on bladder cancer: Focusing on oxidative stress, cellular, and molecular mechanisms

Bladder cancer (BC) is known as a prevalent genitourinary malignancy and has a significant mortality rate worldwide. Despite recent therapeutic approaches, the recurrence rate is high, highlighting the need for a new strategy to reduce the BC cell progression. Quercetin, a flavonoid compound, demonstrated promising anticancer properties and could be used in the management of various malignancies such as BC. This comprehensive review summarized quercetin's cellular and molecular mechanisms underlying anticancer activities. The study's findings indicated that quercetin prevents the proliferation of the human BC cell line, promotes apoptosis of BIU-87 cells, reduces the expression of p-P70S6K, and induces apoptosis by p-AMPK. Moreover, quercetin restricts tumor growth through the AMPK/mTOR cascade and prevents colony formation of human BC cells by triggering DNA damage. Studying this review article will help researchers better understand quercetin's functional role in the prevention and treatment of BC.

Seropositivity for Viral Infectious Diseases in Leukemia Patients and Its Relationship with Cytogenetic Changes

Introduction: Leukemias are involving the bone marrow and the soft tissues in the inner parts of the bones. This malignancy is the most common pediatric cancer, and its etiologic causes are not well understood. This multifactorial disease is believed to be linked to genetic and non-hereditary environmental factors. Cytogenic analyses of chromosomal abnormalities provide diagnostic and prognostic values in leukemia patients. Given the high prevalence of viral diseases and clinical suspicions of the relationship between certain viral infections and leukemia, it is necessary to investigate this possible relationship, especially in third-world countries. The present study recruited 65 children with leukemia (AML, CML, or ALL) who were presented to two tertiary hospitals. At first, all the patients underwent testing for HBV, HCV, CMV, EBV, and HIV. Bone marrow specimens were studied for identifying possible chromosomal abnormalities in cytogenic investigations. According to our findings, there was a relationship between the incidence of leukemia, the 12:21 chromosomal translocation, and CMV infection. Therefore, preventing CMV infection can lead to a reduced incidence of leukemia. It is expected that the findings of this study enlighten scientists to conduct more extensive research on the relationship between viral diseases and leukemia in third-world countries. Materials and Methods: The present study recruited 65 children with leukemia (AML, CML, or ALL) who were presented to two tertiary hospitals. At first, all the patients underwent testing for HBV, HCV, CMV, EBV, and HIV. Bone marrow specimens were studied for identifying possible chromosomal abnormalities in cytogenic investigations. Results: According to our findings, there was a relationship between the incidence of leukemia, the 12:21 chromosomal translocation, and CMV infection. Thus, CMV infection is highly suspected to cause a chromosomal abnormality and predispose children to leukemia . Therefore, preventing CMV infection can lead to a reduced incidence of leukemia. Conclusion: In this study, we demonstrated that acute Lymphoblastic Leukemia is relevant to the 12:21 chromosomal translocation and CMV virus infections, So the reduction in leukemia prevalence is dependent on the prevention of CMV disease. It is expected that the findings of this study enlighten scientists to conduct more extensive research on the relationship between viral diseases and leukemia in third-world countries.
