<p>&nbsp;</p>
<p>New methods include protein microarrays, <u><strong>immunoaffinity chromatography followed by mass spectrometry(MALDI-TOF mass spectrometry), </strong> </u>and combinations of experimental methods such as phage display and computational methods.</p>
<p>&nbsp;</p>
<p><strong><u>Therefore, Focus more on protemoics, Metabolome!</u></strong></p>

<p>-&gt; Illustration of the major physiological and metabolic</p>
 
<p>processes with which adipose tissue is involved through the secretion</p>
 
<p>of various adipokines from adipocytes. The interactions may be</p>
 
<p>autocrine, paracrine, or endocrine.</p>

<p><strong><span style="font-size:16px">&lt;What is Col6?&gt;</span></strong></p>
 
<p>- COL6 = Collagen type 6</p>
 
<p>- Abundant constituent of white adipose tissue (WAT)</p>
 
<p>- COL6 levels positively correlate with hyperglycaemia and insulin resistance</p>
 
<p>- Composed of three distinct a chains, a1, a2 and a3.(COL6 trimeric building block) and are subsequently secreted into the ECM</p>
 
<p>&nbsp;</p>
 
<p><strong><span style="font-size:16px">&lt;What is a3 Chain?&gt;</span></strong></p>
 
<p>-&gt; longest of the three chains</p>
 
<p>- contains an unusually long N terminus and a globular C5 domain at the C-terminus</p>
 
<p>&nbsp;</p>
 
<p>-&gt; C-terminal portion of the a3 subunit is cleaved off during the post-translational processing of COL6 fibrils(COL6a3, Endotrophin)</p>
 
<p>&nbsp;</p>
 
<p><strong><span style="font-size:16px">&lt;What is Endotrophin?&gt;</span></strong></p>
 
<p>- Adipokine with potent tumour-promoting effects</p>
 
<p>- Plays a pivotal role in shaping a metabolically unfavorable microenvironment in adipose tissue during consumption of a high-fat diet (HFD)</p>
 
<p>- Powerful co-stimulator of pathologically relevant pathways within the &lsquo;unhealthy&rsquo; adipose tissue milieu, triggering fibrosis and inflammation and ultimately leading to enhanced insulin resistance&amp; metabolic dysfunction.</p>
 
<p>- Exerts a major influence in adipose tissue</p>
 
<p>- Endotrophin within the tumor microenvironment serves as a major mediator of COL6-stimulated mammary tumor growth and subsequent chemo resistance</p>
 
<p>- Stimulates fibrosis, activates endothelial cell migration and promotes macrophage infiltration into growing solid tumors.</p>
 
<p>=&gt; elevated mammary tumor expansion and more pronounced metastatic growth</p>

<p>&nbsp;</p>
 
<div><strong>-&gt; Find the Receptor according to the New method of Protemoics.</strong></div>
 
<div><strong>-&gt; Find the interaction, relationship and mechanisms how they act.(Study of Omics)</strong></div>
 
<div><u><strong>&nbsp;-&gt; Omics could be applied to genomics perspective!</strong></u></div>
