SOCS3 inhibits many of the same cytokine/growth factor receptor systems as SOCS1
(Table 2), including LIF/IL-6, IL-4, GH, IFN, and PRL.

The new research suggests that the effects of SOCS1
loss in patients might also disable the p53 tumour suppression pathway.

and SOCS3," Arteriosclerosis, Thrombosis, and Vascular Biology, vol.
To investigate the mechanism by which DJC inhibits AGEs-induced JAK2-STAT1/STAT3 activation in GMCs, we further examined the effects of DJC on AGEs-mediated SOCS1
and SOCS3 proteins expression.
These changes are often already present at early stages of carcinogenesis and lead to the silencing of relevant tumor suppressor genes that are involved in cell cycle regulation [GDKN2A  /[p16.sup.TNx4a]) CDKN2B ([p15.sup.INx4b]) RB1 (Rb)], apoptosis [DAPK1, WIF1, PYCARD (TMS1)], WNT signaling (APC, DKK1, IGFBP3), growth signal autonomy (RASSFIA, SOCS1
), hormone response (ESR1, PGR, AR), angiogenesis [THBS1 (thrombospondin)], cell adherence and invasion [CDH1 (E-cadherin), CDH13], detoxification (GSTP1), and DNA repair (MLH1, MGMT) (5, 6).
To explain the mechanisms by which miR155 is associated with inflammation, researchers found that suppressor of cytokine signaling 1 (SOCS1
) is probably one of the most important targets of miR-155; by interacting with its 3' UTR region, it decreases SOCS1
transcription and therefore its availability, which normally functions as a negative regulator of cytokine signaling and targets proteins for degradation by the proteasome.
Of the eight family members, socs1
and socs3 are the most potent inhibitors of cytokine signaling mediated by the JAK/STAT pathway [18, 19].
is also involved in the wound healing process and is responsible for regulation of cytokine signaling during inflammation and macrophage activation [47,48].
C4 has also been reported to induce expression of inhibitors of TLR signalling pathways , but we found that C4 significantly decreased mRNA expression of TLR signalling inhibitors SOCS1
and Tollip and did not affect expression of SOCS3 or ST2 (Figure 3(b)).
For example, astilbin alleviated contact hypersensitivity by inhibiting Th1 cytokine production and stimulating endogenous interleukin-10, and it upregulated the downstream proteins of interleukin-10, suppressor of cytokine signaling 1 (SOCS1
), and SOCS3.

) and SOCS3 in glia," The Journal of Biological Chemistry, vol.
Substantive meta-analysis studies show that HCC tumours exhibit consistent CpG island promoter hypermethylation of classical tumour suppressor genes such as ras association domain family 1A (RASSF1A), [p16.sup.ink4[alpha]a/cyclin dependent kinase inhibitor 2A (CDKN2A), p15, suppressor of the cytokine signalling 1 (SOCS1
), E-cadherin (CHD1), and glutathione-S-transferase Pi 1 (GSTP1) [42, 43] (Figure 1).
Increased expression of SOCS1
and SOCS3 was seen in biopsies of patients with DKD when compared to those with minimal change disease .
