The dd-PCR plot shows that mcr-2a and mbac, which were not detected by RT-PCR, were more abundant in digesters A and B, respectively. Both datasets indicated that operational temperature was an important factor for explaining the community variation, which is consistent with previous observations by Levén et al. [11] Ku-0059436 nmr and Zielinska et al. [19], who reported that temperature is the key determinant of

growth of specific methanogens when the microbial communities of mesophilic and thermophilic digesters were compared. In summary, both technologies exhibited nearly identical PCR efficiencies and the same detection limits of detection. However, dd-PCR was more sensitive for DNA quantification than qPCR. The two technologies

showed quantitative agreement on the methanogen groups that were detected by both of them. In addition, both datasets revealed similar community comparison results. Therefore, dd-PCR is very promising for examining mcrA-based methanogen communities as an alternative to qPCR.

“Matrix metalloproteinase 1 (MMP1), the member of MMP family, is a kind of zinc and calcium-dependent endopeptidase and collagenase that are able to degrade essentially all extracelluar matrix (ECM) components, such as basement membranes, collagen, and fibronectin [23], [16] and [24]. The human MMPs family, which consists of at least 26 proteases, can be divided into several subgroups according to their structure and substrate specificity [22] and [28]. These subfamilies include collagenases, gelatinases, stromelysins, matrilysins, and membrane-type MMPs (MT-MMPs), among others. MMPs play

an important role in both physiological and pathological conditions, including tissue regeneration, RVX-208 wound repair, reproduction, arthritis, atherosclerosis, and autoimmune blistering disorders of the skin [3]. MMPs have also been implicated in carcinogenesis because of their ability to degrade ECM, which is a key event in cancer progression [7]. Growing evidence has shown that MMPs can facilitate tumor growth, invasion, and metastasis in various cancers [7]. The ECM is composed of collagen and elastin, and is very important for creating the cellular environments during morphogenesis, tissue repair and remodeling [28] and [16]. Degradation of ECM in skin tissue would cause skin wrinkle [8]. The human MMPs family, which consists of at least 26 proteases, can be divided into several subgroups according to their structure and substrate specificity [22] and [28]. These subfamilies include collagenases, gelatinases, stromelysins, matrilysins, and membrane-type MMPs (MT-MMPs).
