25846879 PPP1R3C, a novel hypermethylated gene in colorectal cancer, may play a critical role in cancer cell growth in association with glucose levels.
24861485 detection of methylation of PPP1R3C alone or in combination with EFHD1 in plasma DNA showed high sensitivity and specificity in CRC detection, and may be useful detection method for CRC, especially for early-stage CRCs.
21738631 Findings suggest that variations in PTG may condition the course of Lafora disease and establish PTG as a potential target for pharmacogenetic and therapeutic approaches.
20888814 Results demonstrated that HIF1 promotes glycogen accumulation through regulating PPP1R3C expression under hypoxia, which revealed a novel metabolic adaptation of cells to hypoxia.
19171932 phosphorylation of R5/PTG at Ser-8 by AMPK accelerates its laforin/malin-dependent ubiquitination and subsequent proteasomal degradation, which results in a decrease of its glycogenic activity.
