FURTHER TARGETS

WHSC1
 histone-lysine N-methyltransferase NSD2 is an enzyme that in humans is encoded by the WHSC1 gene.[1][2][3]
This gene encodes a protein that contains four domains present in other developmental proteins: a PWWP domain, an HMG box, a SET domain, and a PHD-type zinc finger. It is expressed ubiquitously in early development. Wolf-Hirschhorn syndrome (WHS) is a malformation syndrome associated with a hemizygous deletion of the distal short arm of chromosome 4. This gene maps to the 165 kb WHS critical region and has also been involved in the chromosomal translocation t(4;14)(p16.3;q32.3) in multiple myelomas(WIKIPEDIA)

THERE WAYS TO SUPPRESS SOME OF THE CYTOKINE

 

A unique mRNA initiated within a middle intron of WHSC1/MMSET encodes a DNA binding protein that suppresses human IL-5 transcription.

Abstract

Human interleukin (IL)-5 gene transcription is regulated by several transcription factor binding sites, including CLE 0, GATA, and a region from position -123 to -92 known as response element (RE)-II. By expression cloning, a partial protein was identified that bound to concatamers of RE-II. Recombinant protein derived from this initial complementary DNA (cDNA) encoding the partial protein specifically bound to RE-II-containing oligonucleotides in electromobility shift assays."

DTL GENE 

activates  p21

The p21(CIP1/WAF1) protein can also interact with proliferating cell nuclear antigen (PCNA), a DNA polymerase accessory factor, and plays a regulatory role in S phase DNA replication and DNA damage repair. This protein was reported to be specifically cleaved by CASP3-like caspases, which thus leads to a dramatic activation of CDK2, and may be instrumental in the execution of apoptosis following caspase activation. However p21 may inhibit apoptosis and does not induce cell death on its own.[5] Two alternatively spliced variants, which encode an identical protein, have been reported.
p21(CIP1/WAF1) is a CKI that directly inhibits the activity of cyclin E/CDK2 and cyclin D/CDK4/6 complexes. p21 functions as a regulator of cell cycle progression at S phase.[6] The expression of p21 is controlled by the tumor suppressor protein p53. Sometimes,it is expressed without being induced by p53. This kind of induction plays a big role in p53 independent differentiation which is promoted by p21. Expression of p21 is mainly dependent on two factors 1) stimulus provided 2) type of the cell. Growth arrest by p21 can promote cellular differentiation. p21 therefore prevents cell proliferation."
