MARCKS (Regulator of Cytokines and Inflammation), an new gliomagenesis-specific candidate lncRNAs involved in epigenetic regulation, which was induced by multiple TLR stimuli and acted as a master regulator of inflammatory responses. [1].[2].And MROCKI expression is association with violent suicide the mechanism of the MARCKS.[3].

Characteristics
MARCKS harbors an intragenic CpG island and is closely flanked by the uncharacterized MROCKI(hg19: chr6:114,189,179-114,194,512), which codes for an antisense transcript, a long noncoding RNA(ncRNA).[3]
Function
MROCKI changed expression in glioma is methylation-dependent and methylation correlates with WHO malignancy grade. Methylation is also distinctive between astrocytoma I-III and other glioma subtypes and may thus serve as an additional biomarker in glioma diagnosis.[1] MROCKI expression were linked to a reduced risk of certain inflammatory and infectious disease in humans, including inflammatory bowel disease and tuberculosis.[2] MROCKI is acted as a master regulator of inflammatory responses. [2] MROCKI expression is association with violent suicide the mechanism of the MARCKS.[3] Epigenetic changes associated with suicide represent two facets of epigenetic mechanisms related to MROCKI—that is, DNA methylation and ncRNA expression.[3]
Regulation
MROCKI interacted with APEX1 (apurinic/apyrimidinic endodeoxyribonuclease 1) to form a ribonucleoprotein complex at the MARCKS promoter. [2] MROCKI-APEX1 recruited the histone deacetylase HDAC1, which removed the H3K27ac modification from the promoter, thus reducing MARCKS transcription and subsequent Ca2+ signaling and inflammatory gene expression.[2]
Expression
In all glioma subtypes levels of MROCKI were significantly higher in comparison to normal brain reference RNA, and expression was inversely associated with promoter methylation.[1] MROCKI expression is significantly increased in violent suicides irrespective of MARCKS transcription levels.[3]
Diseases
Glioma tumours[1]
