The involvement of apoptosis in neurodegeneration can be detected by quantifying the apoptotic proteins in hippocampal lysate. Apoptosis can occur due to the overproduction of apoptotic proteins under the influence of external trigger or due to the overexpression of the apoptotic genes. Thus, the imbalance in the production of apoptotic proteins can be quantified using the Western blotting technique and the overexpression of apoptotic genes in hippocampal DNA can be quantified using the real-time quantification of mRNA expression of the apoptotic proteins. Here we provide the methodology of detecting the apoptosis-related proteins like Bax and Bcl-2 and their mRNA expression in hippocampal neurodegeneration. In this chapter, we have described the methodology for quantification of mRNA expression of these apoptosis-related proteins in the hippocampal lysate using the real-time quantitative polymerase chain reaction (qPCR) technique and the methodology of detection and characterization of respective protein expression in the hippocampal lysate using the Western blotting technique.

The developmental competence and epigenetic progression of oocytes gradually become dysregulated with increasing maternal age. However, the mechanisms underlying age-related epigenetic regulation in oocytes remain poorly understood. Zygote arrest proteins 1 and 2 (ZAR1/2) are two maternal factors with partially redundant roles in maintaining oocyte quality, mainly known by regulating mRNA stability.

No biomarker can effectively screen for early gastric cancer (EGC). Players in the A disintegrin and metalloproteinase (ADAM)-natural killer group 2 member D (NKG2D) receptor axis may have a role for that. As a proof-of-concept pilot study, the expression of ADAM8, ADAM9, ADAM10, ADAM12, ADAM17, and major histocompatibility complex (MHC) class I chain-related sequence A (MICA), a ligand for NKG2D, in gastric cancer was investigated in silico using The Cancer Genome Atlas (TCGA) database.

Background: Messenger RNA 3' untranslated regions (3'UTRs) control many aspects of gene expression and determine where the transcript will terminate. The polyadenylation signal (PAS) AAUAAA (AATAAA in DNA) is a key regulator of transcript termination and this hexamer, or a similar sequence, is very frequently found within 30 bp of 3'UTR ends. Short interspersed element (SINE) retrotransposons are found throughout genomes in high copy numbers.

Oxidative stress caused by reactive oxygen species (ROS) and superoxides is linked to various cancer-related biological events. Extracellular superoxide dismutase (SOD3), an antioxidant enzyme that removes superoxides, contributes to redox homeostasis and has the potential to regulate tumorigenesis. Histone deacetylase 6 (HDAC6), a major HDAC isoform responsible for mediating the deacetylation of non-histone protein substrates, also plays a role in cancer progression.
