The emergence of colistin resistance may be related to drug-selection pressure, but horizontal transmission is a recognized cause of acquisition, and gene transfer factors (i.e., transposons and integrons) may also be involved [ 22– 22].
Mutations in those receptors have been reported to be the cause of resistance acquisition [ 8].
9– 11 In a majority of cases, the hyperactivation of MAPK pathway is caused by acquisition of oncogenic mutation in BRAF or NRAS genes.
It also appears unlikely that any further intensifying of instruction in English would cause the rate of acquisition to become much faster.
In the present study, the day/night temperature in the greenhouse cells were 25/16 ± 2 °C, if the soil temperature was the same, then 2.4 °C increase of soil temperature in the AW treatment would result in soil temperature much higher than the optimal, i.e., 20 °C, thus might have negatively affected the root growth of the wheat plants causing a reduction of acquisition area for mineral nutrients.
Exogenous TM1 expression can reverse transformation, suggesting a direct role for TM1 in transformation (Prasad et al, 1993; Braverman et al, 1996; Shah et al, 2001) and, conversely, enforced downregulation of TM1 causes the acquisition of transformed characteristics (Boyd et al, 1995).
Repeated hospital admissions and transfer of patients with MRSA between hospitals are identified as causes of nosocomial MRSA acquisition [ 6].
The transfer of colonized or infected patients between hospitals, and repeated hospital admissions were identified to be the two major causes of nosocomial MRSA acquisition [ 2, 3].
In support of accumulating human data associating cadmium exposure with pancreatic cancer (Adams et al. 2012; Amaral et al. 2011; Kriegel et al. 2006; Schwartz and Reis 2000), the present study shows chronic in vitro exposure to a nontoxic, low level of cadmium causes acquisition of multiple tumor cell characteristics in normal human pancreatic epithelial cells.
The SNAIL transcription factor inhibits the expression of genes encoding adhesive proteins and causes the acquisition of migratory and invasive phenotype of epithelial cells, and is thus considered an important factor of malignancy.
In Luliang, men migrated temporarily from villages to cities due to multiple causes: the acquisition of farmland for the construction of reservoirs; the lease of land to companies for tobacco plantations; and the lure of attractive job opportunities outside the village.
