It is essential that we understand the global scope and dynamic range of this complex and widespread class of PTMs before we can unlock the full therapeutic potential of protein lipidation.

“The abbreviation and chemical name DOTP, dioctyl terephthalate should be DOTP, 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetrakis(methylenephosphonate). These occur in three places in the paper: on p. 211 in the Abstract and the Introduction, and on p. 212 in the Experimental section. “
“Some explanations can be found with a closer look at enhanced

cell communication and motility by endogenous electrical signals (electro-taxis). Dunkin et al1 found that skin cuts to a depth of 0.5–0.6 mm close by electrical cell stimulation without any trace of scar tissue. Zhao et al2 reported similar effects of electrical currents on cell motility and healing. Deeper skin cuts close by “skin repair” that ultimately results in scar formation Figure 1.

In 2010 Liebl proposed that microneedling could be used in treating chronic wounds. In reviewing the literature related to wound healing by electric field stimulation, he theorized that the mechanisms for the main action of microneedling may include trans-epithelial potentials (TEPs) and the skin battery.3 Foulds and Barker4 placed electrodes on the stratum corneum (SC) and inside the dermis, and measured a negative potential Liothyronine Sodium difference of the SC ranging from 10 to 60 mV, and averaging −23.4 mV (Figure 2). When a medical grade, non-traumatic microneedle, preferably made from stainless steel, enters the SC and is pushed into the electrolyte of the intercellular space, the only possible reaction is a short circuit of the endogenous electric fields (Figure 3). It must be noted that the needle penetration lasts only fractions of seconds while the microneedles of the device (e.g. Dermaroller®) roll over the skin. Non-traumatic microneedles with a preferable tip radius of not more than 2–3 μm do not create a classical wound that bleeds. Figuratively speaking, an ordinary hypodermic needle merely “pushes” cells aside. In a classical wound usually bleeding occurs from punctured or cut vessels. In contrast during microneedling there is minimal to no bleeding since only capillaries are punctured. Never-the-less, the mild trauma to the skin results in a mild inflammatory response, likely due to bradykinins and histamine release from mast cells.
