The mec-5 and mec-9 genes encode putative extracellular proteins that allow a set of six touch receptor neurons in C. elegans to respond to gentle touch. MEC-5 is a collagen made by the epidermal cells that surround the touch cells. Mutations causing touch insensitivity affect the Gly-X-Y repeats of this collagen. mec-9 produces two transcripts, the larger of which is expressed in the touch cel...

Community acquired-methicillin resistant Staphylococcus aureus (CA-MRSA) is a socially problematic pathogen that infects healthy individuals, causing severe disease. CA-MRSA is more virulent than hospital associated-MRSA (HA-MRSA). The underlying mechanism for the high virulence of CA-MRSA is not known. The transcription product of the psm-mec gene, located in the mobile genetic element SCCmec ...

Inactivation of the ARF-p53 tumor suppressor pathway leads to immortalization of murine fibroblasts. The role of this pathway in immortalization of human epithelial cells is not clear. We analyzed the functionality of the p14(ARF)-p53 pathway in human mammary epithelial cells (MEC) immortalized by human papillomavirus 16 (HPV16) E6, the p53 degradation-defective E6 mutant Y54D, or hTERT. E6-MEC...

Mobile edge computing (MEC), affords service to the vicinity of mobile devices (MDs), has become a key technology for future network. Offloading big data to the MEC server for preprocessing is a attractive choice of MDs. In the paper, we investigate data offloading from MDs to MEC servers. A coalitional game based pricing scheme is proposed. We apply coalitional game to depict the offloading re...

Background CoNS species are likely reservoirs of the staphylococcal cassette chromosome mec (SCC mec ) in Staphylococcus aureus . S . aureus CC395 is unique as it is capable of exchanging DNA with CoNS via bacteriophages, which are also known to mediate transfer of SCC mec . Objectives To analyse the structure and putative origin of the SCC mec element in S . aureus CC395. Methods The only ...

Selective protein degradation is a key regulator of neuronal development and synaptogenesis. Complexes that target proteins for degradation often contain F-box proteins. Here we characterize MEC-15, an F-box protein with WD repeats, which is required for the development and function of Caenorhabditis elegans touch receptor neurons (TRNs). Mutations in mec-15 produce defects in TRN touch sensiti...

We examined the repertoire and extent of inflammation dependent gene regulation in a bovine mammary epithelial cell (MEC) model, to better understand the contribution of the MEC in the immune defence of the udder. We challenged primary cultures of MEC from cows with heat inactivated Escherichia coli pathogens and used Affymetrix DNA-microarrays to profile challenge related alterations in their ...

BACKGROUND While microbial electrolysis cells (MECs) can simultaneously produce bioelectrochemical hydrogen and treat wastewater, they consume considerable energy to overcome the unfavorable thermodynamics, which is not sustainable and economically feasible in practical applications. This study presents a proof-of-concept system in which hydrogen can be produced in an MEC powered by theoretical...

Mechanotransduction in Caenorhabditis elegans touch receptor neurons is mediated by an ion channel formed by MEC-4, MEC-10 and accessory proteins. To define the role of these subunits in the channel’s response to mechanical force, we expressed degenerin channels comprised of MEC-4 and MEC-10 in Xenopus oocytes and examined its response to laminar shear stress (LSS). Shear stress evoked a rapid ...

Hearing, touch and proprioception are thought to involve direct activation of mechano-electrical transduction (MeT) channels. In Caenorhabditis elegans touch receptor neurons (TRNs), such channels contain two pore-forming subunits (MEC-4 and MEC-10) and two auxiliary subunits (MEC-2 and MEC-6). MEC-4 and MEC-10 belong to a large superfamily of ion channel proteins (DEG/ENaCs) that form nonvolta...
