Each of these membranes is also home to proteins that transport Ca2+ in the opposite direction, against its electrochemical gradient, the Ca2+-ATPases of the PM (PMCA), ER SERCAand and the Golgi and secretory vesicles (SPCA) (5− 7), for example.
Methods that focus on the original data instead of statistical results have also been developed and these techniques test the joint distribution of the multi-locus data or extract the principal components from the original data, such as in the linear combination test (LCT) [18] and supervised principal component analysis (SPCA) [19].
The concentration of zinc was determined by an atomic absorption spectrophotometer (SPCA-626D, Shimadzu Corporation, Kyoto, Japan).
Small-animal PET imaging was conducted on untreated) and CTX-treated) SPCA-1 human lung adenocarcinoma-bearing nude mice using F-ML-8.
After the PET scans, SPCA-1 lung adenocarcinoma-bearing nude mice were euthanized and the tumor tissues (treated and untreated nude mice tumors) were collected for histologic analysis.
In our PET imaging studies, selective higher uptake of F-ML-8 was observed in the CTX-treated SPCA-1 tumor compared with the untreated tumor models.
Interestingly, ERGIC3 was distributed at the side of nucleus in EPLC-32M1, 801D, and NCI-H446 cells, but uniformly present around nucleus in SPCA-1, GLC-82 and A549 cells.
The SPCA-1 tumor models were generated by subcutaneous injection of 5 × 10 human lung adenocarcinoma cells into the right shoulder of female athymic nude mice (Laboratory Animal Center of Sun Yat-sen UniverSun Yat-sen
Similar to the results we found in lung cancer tissues, in the lung cancer cell lines, the mRNA levels of ERGIC3 showed up to 44.9- (in SPCA-1), 61.4- (in EPLC-32M1), 60.8- (in GLC-82), 22.1- (in NCI-H446), 16.0- (in A549), 32.1- (in 801D) fold increase, compared to the immortalized normal bronchial epithelial cells, BEAS-2B.
The tumor uptake of F-ML-8 in treated versus untreated SPCA-1 tumor models was 1.39 ± 0.51 versus 0.52 ± 0.09% ID/g; and the ratios of tumor versus muscle (T/M) in treated and untreated models were 2.46 ± 0.46 versus 1.45 ± 0.25, respectively (n = 4, Figure 5).
p53 expression was higher when cancer NSCLC cells were treated with anti- miR-150 expression vector that indicates that the upregulation of p53 contributes to cancer growth [ 86]. miR-150 targets p53 in NSCLC cell lines (SPCA-1, A549, HCC827, 95-D, and BEAS-2B), which in turn regulates the expression of various tumor-suppressor miRNAs participating in cell cycle progression [ 85].
