Abstract
To evaluate whether human microglia cells (hMG) can be activated by neuromelanin (NM), hMG were cultured with and without the presence of NM for 24 h and then harvested to measure gene expression of selected pro-inflammatory and neurotoxic factors.
RNA is extracted using a RNeasy‱ Mini kit (Qiagen) according to manufacturer’s instructions and quantified with a NanoDrop one spectrophotometer (Thermo Fisher Scientific).
Reverse transcription into complementary cDNA is performed with the Superscript III First-Strand Synthesis System (Invitrogen‱) to a final concentration of 2 ng/μL.
Gene expression is measured by real time quantitative Reverse Transcription Polymerase Chain Reaction (qRT-PCR).
8 ng of cDNA are loaded in every well of a MicroAmp‱ Optical 384-well Reaction Plate (Applied Biosystems‱) with 10 nM of forward and reverse primers (Life Technologies) and PowerUp‱ SYBR‱ Green Master Mix (Applied Biosystems‱).
Plate is run in a 7900HT Fast Real-Time PCR System with 384-well Block Module (Applied Biosystems‱) following a standard cycling mode.
Cycling values are normalized to the housekeeping gene β-Actin and the relative fold gene expression of samples was calculated using the 2-ΔΔCt method.
