Design, Synthesis, and Screening of Novel Phosphatidylinositol 3-Kinase (PI3K) Inhibitors Activated by Prostate Specific Antigen (PSA): Prodrug Treatment for Androgen-Independent Prostate Cancer
… drugs are potent, but often lack the cellular specificity needed to lower toxicity effects. Here we show the design and synthesis of two types of novel PSA-activated PI3K inhibitors for the treatment of androgen-independent prostate cancer. Both literature and predictive molecular modeling …

ΔΙΕΡΕΥΝΗΣΗ ΤΟΥ ΡΟΛΟΥ ΤΟΥ ΕΙΔΙΚΟΥ ΠΡΟΣΤΑΤΙΚΟΥ ΑΝΤΙΓΟΝΟΥ (PSA) ΣΤΗΝ ΠΑΘΟΛΟΓΙΑ ΤΟΥ ΠΡΟΣΤΑΤΗ
WE MEASURED SERUM PROSTATE SPECIFIC ANTIGEN (PSA) FROM 135 MEN (55 PROSTATE CANCER, 39 BENIGN PROSTATE HYPERTROPHY, 9 PROSTATITIS, 32 NORMAL). PSA IS A SPECIFIC-CELL TYPE ANTIGEN OF PROSTATE AND IS MORE SENSITIVE MARKER THAN PROSTATE ACID PHOSPHATASE (PAP)-71% TO 27,3%. PSA CAN NOT SOLVE THE …

Integrative Bioinformatics Approaches to Elucidating Prostate Cancer Cell Heterogeneity, Plasticity, and Treatment Response
<p>Prostate cancer (PCa) is the most common non-cutaneous tumor in American men, and the second leading cause of cancer-related deaths. PCa-related deaths can be attributed to heterogeneous tumors containing metastatic and therapy-resistant cancer cells. Cancer stem cells (CSC) are an important …

Ankstyvosios diagnostikos programos poveikio sergamumui priešinės liaukos vėžiu Lietuvoje vertinimas /
Prostate cancer is most common and second deadliest tumour diagnosed in Lithuanian men. Prostate specific antigen (PSA) test in early detection of prostate cancer could result in decreased morbidity and mortality. Radical treatment of low-risk prostate emerged as an inevitable satellite of early …

An MRI compatible manipulator for prostate cancer detection and treatment
Prostate cancer is the most frequently diagnosed cancer in men and the second most common cause of cancer related death in men. Prostate specific antigen (PSA) blood tests and digital rectal exams (DRE) are preliminary tests that can suggest the presence of prostate cancer. Following these tests, a …

Nanomaterials for the detection of cancer-associated biomarkers
Prostate cancer persists as a major public health issue in the United States and remains the second leading cause of cancer death in men. Early detection and disease monitoring in prostate cancer can significantly improve a patient's prognosis. The advent of prostate-specific antigen (PSA) …

Prostate Specific Antigen Screening in Texas Medicare Population: The Role of Patient Characteristics
… study were to 1) determine the prevalence of prostate specific antigen (PSA) testing in the Texas Medicare population and 2) assess which patient characteristics are associated with receipt of PSA screening. The 100% Texas Medicare claims data and 2009 population estimates from the Dartmouth …

Antibody-based biosensor assays for the detection of zilpaterol and markers for prostate cancer
… and the application of antibodies against prostate-specific antigen (PSA), a cancer marker. Polyclonal antibodies were used in the development of immunoassays in a competitive ELISA format and on the Biacore (a surface plasmon resonance-based optical biosensor capable of monitoring …

Investigation of the anti-cancer effects of rosemary (Rosmarinus Officinalis L.) extract in human breast and prostate cancer cells
Breast and prostate cancer are the most frequently diagnosed cancers in women and men respetively, in North America. Triple-negative breast cancer (TNBC) cells do not express estrogen receptor, progesterone receptor, and human epidermal growth factor receptor-2 (HER-2). TNBC accounts for 15% of all …

Fluorescence resonance energy transfer-based biosensors for monitoring prostate specific antigen
Prostate cancer has become the most commonly diagnosed cancer in men in the United States. Clinical diagnostic procedures currently include prostate-specific antigen (PSA) screening, digital rectal exam, and prostatic needle biopsy. However, these methods lack the sensitivity to detect small …

Characterizing glucocorticoid receptor in metastatic castration resistant prostate cancer
… in the context of enzalutamide resistant prostate cancer cells. Enzalutamide is a drug that functions to dampen androgen receptor (AR) signaling, thus inhibiting cancer dependency on the receptor protein. Although the application of the drug reduces AR signaling in these cancer cells, an …

Prostate-specific Antigen Nadir and Time to Prostate-specific Antigen Nadir Following Maximal Androgen Blockade Independently Predict the Prognosis in Patients with Metastatic Prostate Cancer
PURPOSE: To evaluate the influence of prostate-specific antigen (PSA) kinetics following maximal androgen blockade (MAB) on the disease progression and cancer-specific survival in patients with metastatic, hormone sensitive prostate cancer. MATERIALS AND METHODS: One hundred thirty-one patients …

Risk Factors for Acute Prostatitis after Transrectal Biopsy of the Prostate
… with acute prostatitis after transrectal prostate biopsy. MATERIALS AND METHODS: We retrospectively reviewed the medical records of 923 transrectal ultrasound-guided needle biopsy of the prostate on 878 patients performed in our institution from June 2004 to May 2009. The indications for …

Differences in Lower Urinary Tract Symptoms between Sympathetic Hyperactive and Hypoactive men
… 43 patients with symptomatic LUTS [International Prostate Symptom Score (IPSS) over 8] and 49 healthy volunteers were enrolled. No subjects had diseases that could affect the autonomic nervous system, such as diabetes or hypertension. Electrocardiographic signals were obtained from subjects in the …

Evaluation of a stage II screening protocol for prostate cancer
In 2003, prostate cancer (PCa) is estimated to be the most commonly diagnosed cancer and third leading cause of cancer death in Canada. During PCa population screening, approximately 25% of patients with a normal digital rectal examination (DRE) and intermediate serum prostate specific antigen …

Analysis of N-Linked Oligosaccharides of Prostate-Specific Antigen and Prostatic Acid Phosphatase in Prostatic Fluids
<p>Presently, prostate cancer is the most common cancer afflicting men in the United States, with serum PSA being the "gold standard" protein biomarker used in the clinic for detecting and diagnosing prostate cancer. Nonetheless, serum PSA levels can also be elevated in non-cancerous conditions as …
