Table 2. Differential fold change in expression of cell death genes in human colorectal cancer (HT-29) versus normal colon mucosal epithelia cells.

Anti-Apoptotic Genes
Gene Fold Change (HT-29) Fold Change (NCM460) Gene Function
Bcl-2 (B-Cell Lymphoma 2) −2.2 ± 0.23 +3.2 ± 0.44 An integral outer mitochondrial membrane protein that blocks the apoptotic death by interacting and inhibiting pro-apoptotic proteins, e.g BAX, APAF1 [20]
Bcl-2A1 (Bcl-2 related protein A1) −1.5 ± 0.21 +15.5 ± 1.1 BCL2A1 is a target of NF-kB activation, in response to inflammatory signals. This gene exerts pro-survival functions and is generally overexpressed in several cancers [21]
CD40LG −1.4 ± 0.11 +11.2 ± 0.7 An integral membrane protein and a member of the TNF superfamily, overexpressed in several carcinomas. Enhances cytokine production and promotion of cell proliferation [22]
GALNT5 (polypeptide N-acetylgalactosaminyltransferase 5) −1.8 ± 0.23 +8.5 ± 0.75 A member of the TNF superfamily. They are responsible for the altered O-linked glycosylation occurring during the development of various cancers and their progression via altering O-glycan biosynthesis [23]
PARP2 (poly (ADP-ribose) polymerase 2 −1.2 ± 0.15 +2.2 ± 0.25 Induced by double stranded DNA breaks, as a cellular response to DNA damage. It is involved in DNA repair and transcriptional regulation. PARP inhibitors are an emerging field in cancer therapy [24, 25]
SYCP2 (Synaptonemal Complex 2) −1.3 ± 0.16 +2.0 ± 0.22 A major component of synaptic complexes during meiosis (prophase). May be involved in the organization of chromatin by temporarily binding to DNA scaffold attachment regions [26]
TMEM57 (Transmembrane Protein 57) −1.4 ± 0.25 +1.6 ± 0.25 A target of Jun Kinase signaling. Has been shown to interact with several proteins, including the transcription regulators HTT and SMAD9). Its function is still being studied
ULK1 (Unc-51 Like Autophagy Activating Kinase 1)/ ATG1 −1.3 ± 0.16 +3.1 ± 0.2 A serine/threonine protein kinase involved in autophagy in response to starvation by phosphorylating Beclin-1. Transcriptional activation of ULK1 is involved in cancer cell survival [27, 28]
Pro-Apoptotic Genes
BMF (Bcl-2 modifying factor) +1.4 ± 0.23 +7.2 ± 0.55 A Bcl-2 family membrane that might activate apoptosis and anoikis. Interacts with other members of the Bcl-2 family for apoptosis induction [29, 30]
DEFB1 (Defensin, Beta 1) +1.3 ± 0.09 −40 ± 7.54 Found to be down-regulated in several cancer types and plays a significant role in innate and adaptive immune response to promote cytotoxicity [31]
HSPBAP1 (Heat shock protein 27kDa associated protein 1) +1.1 ± 0.11 +2.5 ± 0.3 May play a role in cellular stress response. Knockdown of this gene is associated with an increase in caspase-3/7 activation [32]
IFNG (Interferon Gamma) +3.3 ± 0.25 +1.5 ± 0.5 Coordinate various cell response programs, including macrophage activation, inhibition of cell proliferation and activation of apoptosis [33]
NFKB1 (Nuclear factor kappa B) +1.1 ± 0.11 −2.3 ± 0.3 Has both pro- and anti-apoptotic activities; a major transcription factor in various cell signaling pathways [34, 35]
TNFRSF1A (Tumor Necrosis Factor Receptor Superfamily, Member 1A) +1.5 ± 0.15 −2.2 ± 0.3 Member of the TNF superfamily. Recruits adapter domains such as FADD and TRADD for activation of extrinsic apoptosis [36]
CASP1 (Caspase-1) +12.3 ± 2.1 −2.5 ± 0.25 Cleaves a variety of substrates (121 substrates), including pro-inflammatory cytokine pro-interleukin (IL)-1β to induce apoptosis (pyroptosis) [37]
SNCA (Alpha synuclein) +3.0 ± 0.14 −4.8 ± 0.45 A biomarker of colorectal cancer, and overexpressed in various other cancers; might be involved in cell death activation in certain cell types [38, 39]
TNF +8.3 ± 0.32 −7.5 ± 0.55 A cytokine that binds to its receptors (TNFR1, TNFRSF1A) and promotes extrinsic apoptosis under ideal conditions [40]
Pro-Autophagic Genes
GAA (Acid alpha glucosidase) +1.2 ± 0.22 +9.9 ± 0.34 Active in the lysosomes for the breakdown of glycogen into glucose. Plays a role in autophaic induction by encouraging the degradation of p62 conjugated cargo [41]
