Positive correlation between TMEM106B and neurofilament, heavy polypeptide mRNA levels. Neurofilament, heavy polypeptide (NFH), glial fibrillary acidic protein (GFAP), and RNA-binding protein, fox-1 homolog (Caenorhabditis elegans)-3 (RBFOX3, NEUN) mRNA expression levels were studied by quantitative reverse transcriptase-polymerase chain reaction (qPCR) in human brain tissues derived from a reference of the human frontal cortex (REF), four non-neurological causes (NC) cases, six amyotrophic lateral sclerosis (ALS) cases, four Parkinson’s disease PD cases, and seven AD cases. The expression levels were standardized against those of G3PDH. (a) NFH expression. (b) GFAP expression. (c) NEUN expression. (d) Pearson’s correlation between TMEM106B and NFH mRNA levels. Pearson’s correlation coefficient indicates 0.496 (P = 0.0221).
