Abstract:
Renal cell carcinoma (RCC) is the most common malignancy of the kidney. Since RCC is curable when it is confined to the renal capsule, early diagnosis is extremely important. Promoter hypermethylation is the most common mechanism for the inactivation of the tumor suppressor genes (TSG) in the development of human cancer. This study aimed to investigate the methylation profiles of 7 TSG (RASSF1A, ECAD, TIMP3, APC, MGMT, p16 and RARbeta2) in 3 different tissue samples (normal, premalign, malign) of patients with RCC. Twenty-one patients diagnosed with RCC were included in the study. Methylation-specific polymerase chain reaction was performed to detect the methylation patterns of the 7 TSG. High methylation rates for the genes RASSF1A (76%), p16 (80%), ECAD (42%), TIMP3 (33%) and MGMT (33%) were observed in the patients with RCC. The APC (14%) and RARbeta2 (19%) genes showed low methylation rates. In conclusion, 5 TSG (RASSF1A, ECAD, TIMP3, MGMT and p16) showed high methylation rates in RCC patients. A methylation-based gene test including these genes may be useful in the early detection of RCC.

Factors Affecting Renal Clearance: Renal Impairment
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...

Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...
Renal Clearance
Renal clearance refers to the volume of plasma cleared of a specific substance, such as creatinine, per unit of time. To measure clearance, urine samples are collected over a 24-hour period during each bladder voiding, followed by a single blood sample at the...
Renal Drug Clearance: Comparison Between Renal Excretion Methods
Renal clearance is often associated with the renal glomerular filtration rate (GFR), which represents the rate at which plasma is filtered through the glomeruli in the kidney. When drug reabsorption is minimal and there is no active secretion, renal clearance is closely related to the...
