| Source name |
Human frontal cortex (BA10)
|
| Organism |
Homo sapiens |
| Characteristics |
Sex: Male
age: 58 yr
genome build: hg19
library strategy: snmC-seq + SAP
|
| Growth protocol |
Male C57Bl/6J mice were purchased from Jackson laboratories at 8 weeks of age and maintained in our facility for 48h before dissection. Animals were maintained in the Salk animal barrier facility on 12h dark-light cycles with food ad-libitum. Human brain specimens were obtained from University of Miami Brain Endowment Bank. snmC-seq with Shrimp Alkaline Phosphatase treatment (snmC-seq + SAP) was applied to frontal cortex (Brodmann Area 10, BA10) tissue of a deceased 58-year-old Caucasian male with PMI = 23.4. snmC-seq2 was applied to BA10 tissue of a deceased 25-year-old Caucasian male with PMI = 20.8.

| Extraction protocol |
Bisulfite-converted samples were denatured at 95°C for 3 minutes, then placed on ice for 2 minutes. 5µL Random Priming master mix [1µL 10x Blue Buffer (Enzymatics B0110), 0.25µL Klenow Exo- (50U/µL, Enzymatics, P7010-HC-L), 0.5µL dNTP (10mM each, NEB N0447L), 3.25µL water] was added and incubated at 4°C for 5 min, 25°C for 5 min, and 37°C for 60 min followed by 4°C. 1.5µL enzyme mix containing Exonuclease 1 (20U/µL, Enzymatics X8010L) and rSAP (1U/µL, NEB M0371L) was added, then incubated at 37°C for 30 min followed by 4°C. 0.8x SPRI beads were added, mixed and incubated for 5 minutes at room temperature to allow DNA to bind. The beads were washed 3 times with 80% ethanol and eluted in 10µL EB buffer (Qiagen 19086). The plates were denatured again at 95°C for 3 minutes, and 10.5µL Adaptase master mix [2µL G1, 2µL G2, 1.25µL G3, 0.5µL G4 and 0.5µL G5 (Swift Biosciences 33096)] was added and incubated at 37°C for 30 minutes, then 95°C for 2 minutes. 25µL 2x KAPA HiFi HotStart ReadyMix (Kapa, KK2602) and 5µL custom indexing primer mix (6µM P5, 10µM P7) were added. The PCR was programmed as follows: 1) 95°C 2 min, 2) 98°C 30 sec, 3) 98°C 15 sec, 4) 64°C for 30 sec, 5) 72°C for 2 min, 6) 72°C 5 min, 7) 4°C hold. Repeat steps 3-5 for 15 total cycles. PCR reactions were cleaned with 0.8X SPRI beads for three rounds. Library concentration was determined with Qubit™ dsDNA BR Assay Kit (ThermoFisher Q32853). Libraries were sequenced using Illumina Novaseq instrument.

| Data processing |
Sequencing reads mapping, quality filtering and the summary of DNA methylation level for each cytosine was performed as previously described in Luo et al., 2017 with minor modifications. Non-clonal mapped reads were filtered for MAPQ > 10 using samtools view -bq10 option.
Supplementary_files_format_and_content: tab delimited text files of methylcytosine calls; columns in allc files are: column 1 - chromosome; column 2 - position; column 3 - strand; column 4 - class; column 5 - mC reads; column 6 - total reads; column 7 - methylated (Boolean value indicating the result of statistical test for methylated cytosines)
