    1. he discussed studies have shown that persistent abnormalities in epigenetic markers have been detected in the brain tissues as well as peripheral biospecimens of schizophrenia patients, however, the results need to be further confirmed across multiple studies and the mechanisms behind need to be further investigated

      The impact of samples outside of brain tissues, such as the immune cells mentioned above, emphasizes the impact Schizophrenia has on a person. This mental disorder affects much more than just the brain- while scientists do not have many clear studies on this, the understanding of how Schizophrenia functions would grow deeper from studying the function of epigenetics on other peripheral biospecimens within the body.

    2. Higher level of methylation in CpG in gene SLC20A1 has been associated with current suicidal ideation in schizophrenia

      A correlation in higher suicide rates and increased hyper-methylation of serotonin receptors, another essential neurotransmitter, is not only extremely scary, but also does make sense because of serotonin's key functions as a communicator. Specifically, it is associated with mood correlation, learning and memory (see annotation above), and sleep. Going off of the data presented in above paragraphs, this evidence strengthens the claim that Schizophrenia is heavilly associated with memory and learning blockage.

    3. as well as two CpG loci in promoter of glutamic acid decarboxylase 1 (GAD1), which is the enzyme controling synthesis of GABA and associated with schizophrenia-risk single nucleotide polymorphism (SNP)

      GABA is a neurotransmitter that slows the activity of neurons; therefore, it is interesting that hyper-methylation occurs where GABA is synthesized. The receptor sites of neurotransmitters are essential to the cells' communication, and as discussed within lecture and lab, cell communication is essential to cell differentiation, and is a large part of epigenetics when comparing what genes are expressed and which ones are not.

    4. so that BDNF DNA methylation in the blood can be used as a novel biomarker for early detection of many mental diseases

      The correlation with a memory BDNF gene being methylated and the expression of not even just Schizophrenia, but many other mental disorders in general, raises questions of just how important the ability to learn and maintain information is relevant to dangerous mental disorders. This also makes me question what other genes associated with memory, learning, and neuronal development could be impacting the development of diseases such as Schizophrenia.

    5. The correlation between histone modification and schizophrenia, however, is largely unclear.

      There is much more sequencing and experimenting to be done to determine the overall impact of epigenetics on Schizophrenia. Nothing is set in stone, only observations of a vast number of genes has been collected. There is much more that can impact Schizophrenia then just the genes recognized, and that is extremely important to remember when doing research about the mental disease.

    6. Specific changes of non-coding RNAs,

      This is an example of how dark matter/non-coding genes do have longterm impact on organism function! It would be interesting to see the impact on the organism if these non-coding RNAs had other modifications done onto them, because they are not the only thing triggering Schizophrenia to develop, or even if only half of this noncoding RNA was not modified.

    7. Firstly, both DNA hypermethylation and hypomethylated have been associated with schizophrenia

      Hypermethylation prohibits transcription factors from binding with DNA- this means that Schizophrenia, regarding the specific genes being referenced, stems from the inhibition of the Central Dogma process.

    8. Both genetic and environmental factors are considered as important contributors to the development and progression of this disorder.

      This is interesting because from scouting on the web, most clinics and reliable resources have a tendency to fixate on environmental impacts that lead to Schizophrenia- that being said, one thing I would like to stress using this paper with our project is how both genetic and environmental impacts play a large role in Schizophrenia's development.
