Clinical significance of acidic pI isoenzyme of ribonuclease in human serum: Clinical significance of acidic pI isoenzyme of ribonuclease in human serum. Hishiki, Shuji; Sakaguchi, Shukichi; Kanno, Takashi (Sch. Med., Hamamatsu Univ., Hamamatsu City, Japan). Clin. Chim. Acta, 136(2-3), 155-64 (English) 1984. CODEN: CCATAR. 9001-99-4 which is the cas registry number is also used here. ISSN: 0009-8981. DOCUMENT TYPE: Journal CA Section: 14 (Mammalian Pathological Biochemistry) Section cross-reference(s): 9 Three major isoenzymes (basic, neutral, and acidic) of RNase were found in human blood serum. The acidic isoenzyme was obsd. in pancreatic and hepatic cancer cells and in fetal pancreas and liver; it was frequently detected in the sera of patients with pancreatic and hepatic cancer. This isoenzyme was not, however, detected in the sera of non-cancerous patients. In pancreatic cancer tissues, other isoenzymes, except for the acidic one, were suppressed and the isoelectrophoretic patterns of the cancerous tissues closely resembled those obtained from fetal pancreatic tissue. The acidic isoenzyme could represent one of the carcinofetal proteins and the detection of this isoenzyme in the patient's serum may be useful for the diagnosis of pancreatic and hepatic cancer. .

Preparation of 3'-ribonucleotides by the enzymic method: Preparation of 3'-ribonucleotides by the enzymic method. Sun, Rongrong (Shanghai Chem.Several substances are used for example 84-52-6 and 9001-99-4 which are their cas registry numbers. Reagent Works, Shanghai, Peop. Rep. China). Huaxue Shiji, 5(2), 103-6 (Chinese) 1983. CODEN: HUSHDR. DOCUMENT TYPE: Journal CA Section: 16 (Fermentation and Bioindustrial Chemistry) 3'-Ribonucleotides were produced from RNA by RNase [9001-99-4] from Rhodotorula gracilis. The nucleotides were sepd. by chromatog. on a strongly basic anion exchanger into the 4 major nucleotides, 3'-AMP [84-21-9], 3'-CMP [84-52-6], 3'-UMP [84-53-7], and 3'-GMP [117-68-0], and were also concd. by ion-exchange chromatog. .
