Can L-Ergothioneine and Pyrroloquinoline Quinone Work Together?

Last time, we said that L-Ergothioneine (EGT) and taurine work well together, because the pair forms a “Shield and Supply” combo. This week, we introduce a new pair, namely, EGT and Pyrroloquinoline Quinone (PQQ), as the combo of “Shield and Spark” to boost mitochondrial health.

Why Is PQQ Unique?

Like both EGT and taurine, PQQ is a powerful antioxidant. But unlike either member of “Shield and Supply,” PQQ also functions as a cell-signaling modulator, directly stimulating mitochondrial biogenesis.

What Happens During Mitochondrial Biosynthesis?

Mitochondria are cellular power plants. Their biogenesis, where both the individual mass and the total number increase, can be seen as infrastructure construction projects, a process to start only when cell needs more energy. It can be triggered by vigorous exercise, caloric restriction, cold exposure, or in our case, a handful of specific nutrients.

The process entails a complex collaboration between the nucleus and mitochondria themselves. One of the critical players involved is a protein called PGC-1α. When it travels to the nucleus, it kicks off a process that leads to the splitting of an existing mitochondria, essentially doubling the number of power plants.

How Does PQQ Flip The Biogenesis Switch?

When PQQ enters a cell, it activates enzymes, likely AMPK or MARK, which in turn chemically modify a transcription factor called CREB. Studies show that within minutes of PQQ exposure, the modification of CREB can be detected.

When the modified CREB enters the nucleus, it instructs the DNA to start making proteins needed for mitochondrial biosynthesis, one of which is PGC-1α. As the "Master Regulator," PGC-1α then goes on to activate a second wave of factors, including:

• NRF-1 and NRF-2: They tell the nucleus to build some of mitochondrial structural proteins, coded in one’s genome.
• TFAM: It enters the mitochondria to begin the synthesis of the rest of structural proteins, this time coded in mitochondria itself.

Why Is This "Direct"?

Compared to other nutrients, PQQ differs by its ability to simulate a genuine signal that triggers the mitochondrial biosynthesis. In another word, it rewrites the cell's priority list and forces it to focus on "infrastructure construction" projects first.

Why It Matters For Longevity?

As we age, mitochondrial biogenesis becomes sluggish. This leads to conditions such as muscle loss, neurodegeneration, and the struggle to metabolize fat and sugars, often leading to insulin resistance. By rejuvenating the biogenesis "machinery," PQQ keeps cells biologically younger and more resilient to stress.

So, What Is “Shield and Spark”?

In addition to the biogenesis spark induced by PQQ, EGT is there to ensure that all of our power plants are protected from oxidative stress. Two biological processes have been implicated to benefit from their synergy.

• SIRT1/ATM/p53: Based on recent research, the combination of PQQ with other agents (like EGT) are found to activate SIRT1/ATM/p53 signaling pathway, which prevents premature cell aging and untimed programmed cell death.
• Prevention of "Reductive Stress": A direct trigger aside, PQQ also lets mitochondria continue to perform even when the usual pathway is strained. EGT further supports this extra capability by ensuring the enzymes required remain functional.

Therefore, when taken together, PQQ stimulates the growth of new mitochondria, while EGT provides targeted protection to mitochondrial DNA. This can benefit especially someone exposed to a high-stress environment.
