Salk Institute discovers that Serine improves diabetic neuropathy

 Supplementation with amino acid serine eases neuropathy in diabetic mice

 

"Foods naturally rich in serine include soybeans, nuts, eggs, chickpeas, lentils, meat, and fish, and serine supplements are inexpensive and available over the counter."

Lysine and (+) Catechin disable melanoma cells from establishing metastases

 (+)-Catechin in a 1:2 Complex with Lysine Inhibits Cancer Cell Migration and Metastatic Take in Mice

 

10uM preincubation for 6 hours before inoculation into the mice.  This is different from establishing a xenograft and administering catechin:lysine orally.  They openly state that the anti-metastatic activity is independent of a lack of cytotoxic effect, attributed to EGCG, but not catechin. 

 

 

Then one would ask, is 5-10uM Catechin achievable in the blood?   Yes.  Is 5-10uM lysine achievable in blood?  Yes.

One could imagine a solid tumor, when constantly bathed in this complex in a live mammal, would encounter this effect described.  

 

The next step would be to administer this complex by IV catheter and in an oral formulation in mice with established solid malignancy and check for met burden in non-hormone driven malignancy.  I guess that hormone driven malignancies will not respond, but non-hormone driven maligancies will be contained.

Is there any evidence whatsoever that dietary L-Lysine is helpful against atherosclerosis? Yes, but

It was not until 2014, until a group in Japan studied a kidney disease related calcification disorder of the arteries.  It wouldn't be scientific to conflate this discovery to any other etiologies or use this for a cross claim where there was no evidence, although it recommends that L-Lysine be studied in atherosclerosis arrived through various pathologies.  A novel MOA, not considered before is the suppression of iPTH.  Very profound.  Importantly, they do not claim it reverts pre-existing calcification, and that this is an open question.  

The General Electric Lysine-Sepharose column for Lipoprotein(a) purification relies on the lysine binding sites (LBS) of apo(a) to capture it before eluting it with stronger affinity lysine analogs.  The study was never done in rodents to see if lysine could dislodge Lp(a) deposits in atherosclerotic plaque.  There certainly was ample time and resources available to do so and it remains an open question.
