Background: To determine the phytochemical constituents, antioxidant, and anticancer activities of leaf extracts on DU-145 and PC-3 human prostate cancer cell lines.
Methods: Leaf sample was subjected to Soxhlet extraction method with increasing polarity of solvents, namely, chloroform, ethyl acetate, methanol, ethanol, and aqueous. Phytochemical screening was done using different biochemical tests. Quantitative analysis for phenol was determined by Folin-Ciocalteu reagent method. The antioxidant activity was tested using 2,2-diphenyl-1-picrylhydrazyl, ferric ion reducing power assay, and phosphomolybdenum assay. anticancer activity on DU-145 and PC-3 human prostate cancer cell lines was evaluated by (3-(4, 5-dimethyl thiazole-2yl)-2, 5-diphenyl tetrazolium bromide) MTT assay.
Results: Phytochemical screening confirmed the presence of phyto-constituents like alkaloids, flavonoids, glycosides, phenols, lignins, saponins, sterols, tannins, anthraquinone, and reducing sugar. Methanol and ethanol extracts exhibited higher phenolic content as compare to aqueous extract. Antioxidant capacities were shown highest in methanol and ethanol extracts based on the test performed. The methanol and ethanol leaf extracts were found to be selectively cytotoxic to (DU-145 and PC-3) prostate cancer cell lines with IC values 529.44 ± 42.07 μg/mL and 677.11 ± 37.01 μg/mL for DU-145 and 547.55 ± 33.52 μg/mL and 631.99 ± 50.24 μg/mL for PC-3 respectively, while it had no cytotoxic effect on normal mice embryo fibroblast cells.
Conclusion: The results indicate that was a promising antioxidant and anticancer agent for DU-145 and PC-3 human prostate cancer cell lines. However, further studies are needed to conclude its therapeutic use.

Background: The metal oxide nanoparticles possess unique properties such as biological compatibility, superior reactivity, and capacity to develop reactive oxygen species, due to this they have drawn significant interest in cancer treatment. The various MONPs such as cerium oxide, Copper oxide, Iron oxide, Titanium dioxide, and Zinc oxide have been investigated for several types of cancers including brain, breast, cervical, colon, leukemia, liver, lung, melanoma, ovarian, and prostate cancers. However, traditional physiochemical synthetic methods for MONPs commonly include toxic materials, a major concern that raises questions regarding their biocompatibility and safety.

Aims: We aimed to perform a retrospective cohort study using the Centers for Disease Control and Prevention's (CDC's) Wide-Ranging Online Data for Epidemiologic Research (WONDER) database to analyse the trends in cardiovascular disease (CVD)-related mortality in patients with myeloproliferative neoplasms (MPNs) from 1999 to 2020.
Methods And Results: We analysed the death certificate data from the CDC WONDER database from 1999 to 2020 for CVD with co-morbid myeloproliferative disorders in the US population. Age-adjusted mortality rates (AAMRs) and 95% confidence intervals (CIs) were computed per 1 million population by standardizing crude mortality rates to the 2000 US census population.

Doublecortin-like kinase 1 (DCLK1) has been revealed to be involved in modulating cancer stemness and tumor progression, but its role in prostate cancer (PCa) remains obscure. Castration-resistant and metastatic PCa exhibit aggressive behaviors, and current therapeutic approaches have shown limited beneficial effects on the overall survival rate of patients with advanced PCa. This study aimed to investigate the biological role and potential molecular mechanism of DCLK1 in the progression of PCa.

Biochemical recurrence (BCR) is a critical concern in prostate cancer management; however, its underlying genetic determinants remain poorly understood. The () gene family is involved in cellular detoxification and biosynthetic processes and has been implicated in various cancers. This study investigated the association between the family members and prostate cancer recurrence.

The association of prostate cancer with deranged lipid profile and insulin levels is inconsistent and not well understood. This study aimed to analyze the serum levels of lipids, insulin, insulin-like growth factor-1 (IGF-1) and testosterone and to identify their association with the risk of benign prostatic hyperplasia, prostate cancer and its grading.
