Previously, scientific studies have shown that meditation could affect free radical levels and biophoton emissions.  There have been a few studies on meditation and it’s affects on gene expression but no genes seemed to be altered that could increase height during development or reinstate height growth in adults.

Rapid changes in histone deacetylases and inflammatory gene expression in expert meditators

“Here we explored the impact of a day of intensive practice of mindfulness meditation in experienced subjects (n = 19) on the expression of circadian, chromatin modulatory and inflammatory genes in peripheral blood mononuclear cells (PBMC){Ideally we’d like gene expression of the growth plate and bone marrow but this could give us some insight if meditation can alter any genes involved in development processes}. In parallel, we analyzed a control group of subjects with no meditation experience who engaged in leisure activities in the same environment (n = 21). PBMC from all participants were obtained before (t1) and after (t2) the intervention (t2 − t1 = 8 h) and gene expression was analyzed. Both groups were also presented with the Trier Social Stress Test (TSST).
Core clock gene expression at baseline (t1) was similar between groups and their rhythmicity was not influenced in meditators by the intensive day of practice. Similarly, we found that all the epigenetic regulatory enzymes and inflammatory genes analyzed exhibited similar basal expression levels in the two groups. In contrast, after the brief intervention we detected reduced expression of histone deacetylase genes (HDAC 2, 3 and 9), alterations in global modification of histones (H4ac; H3K4me3) and decreased expression of pro-inflammatory genes (RIPK2 and COX2) in meditators compared with controls. We found that the expression of RIPK2 and HDAC2 genes was associated with a faster cortisol recovery to the TSST in both groups.”

HDAC2 binds to the cartilage promotor Sox9 which is a height increase link there.  Although it is not necessarily a positive binding as HDAC2 did repress some cartilage specific genes like Col2a1 in one study.  Since Meditation reduces HDAC2 expression that could be beneficial to height growth.

H3K4me3 is associated with gene activation.  Thus raising the possibility that meditation alters genes other than those listed.  Jeffrey Baron thinks that declining H3K4me3 levels are associated with declining organ growth with age.  Elevated levels of H3K4me3 is associated with chondrogenesis.

“Increased telomerase activity was detected in response [to yogic meditation]”

” Rapid epigenetic changes in response to environmental exposures such as diet and physical exercise have also been detected in human peripheral tissues”

It seems with the genes above mentioned, that meditation has the ability to accelerate but not induce or increase chondrogenesis.  So, you’ll grow taller faster but not taller than you would have.
Meditation would accelerate growth by inhibiting HDAC2 which supresses chondrogenesis.  The elevated levels of H3K4me3 could be a sign of increased gene activation but it’s not likely that H3K4me3 is driving the gene activation.  Whether meditation can activate growth plate inducer genes or genes that enhance growth remains to be seen.
