Also, the 60kDa heat shock protein is a chaperonin mainly involved in mitochondrial protein folding and translocation, but it is also suggested as a danger signal of stressed or damaged cells [54].
A newly designed loop-mediated isothermal amplification (LAMP) assay based on cpn60 (encoding for chaperonin 60) was carried out in a total volume of 25 [micro]L containing 0.5 [micro]L each of pho-F3 and Pyo-B3 primer (25pmol/[micro]L) equivalent to 0.5 [micro]M final concentration, 1 [micro]L each of Pyo-LoopF and Pyo-LoopB primer (25pmol/[micro]L) equivalent to 1.0 [micro]M final concentration, 2 [micro]L each of Pyo-FIP and Pyo-BIP primer (25pmol/[micro]L) equivalent to 2.0 [micro]M final concentration, and 15 [micro]L Isothermal Master Mix Iso-001 (Optigene, Horsham, UK).

MERVL and Zscan4 have recently been reported to be associated with DNA demethylation in the nuclear [33], while the expression of Hsp70.1 (known as a chaperonin) and eIF-1A may affect the process of posttranscriptional regulation in the cytoplasm; thus, the detection of the combination of these four factors may well reflect the cell state.
