Objective:To investigate the mechanism of downregulated programmed cell death 10 ( PDCD10) expression mediating glioblastoma multiforme (GBM) resistance to temozolomide (TMZ). Methods:U87, LN229 and T98g cell lines were transfected with PDCD10 small interfering RNA or negative small interfering RNA. TMZ-resistant cell lines were constructed using 300 μmol/L TMZ (transfected T98g cell line) and 150 μmol/L TMZ (transfected U87 and LN229 cell lines), respectively: TMZ-resistant U87 cell line transfected with PDCD10 small interfering RNA (shPDCD10-U87-RG cells), TMZ-resistant U87 cell line transfected with negative small interfering RNA (EV-U87-RG cells), shPDCD10-T98g-RG cells, EV-T98g-RG cells, shPDCD10-LN229-RG cells and EV-LN229-RG cells. Flow cytometry and real-time quantitative polymerase chain reaction (qRT-PCR) were used to detect the transfection efficiency of TMZ-resistant cell lines and PDCD10 expressions; MTT assay and colony formation assay were used to verify the drug-resistant ability of TMZ-resistant cell lines. Bioinformatics analysis was performed to detect the correlations of PDCD10 with key genes ( MSH6 and PMS2) in mismatch repair (MMR) system, and drug resistant mechanism was explored by detecting the cell cycle and neurosphere formation ability of drug-resistant cells. Results:(1) qRT-PCR showed that compared with that in EV-U87-RG cells, the PDCD10 expression in shPDCD10-U87-RG cells was statistically down-regulated by (32.85±1.14)% ( t=2.925, P=0.049); compared with that in EV-T98g-RG cells, the PDCD10 expression in shPDCD10-T98g-RG cells was significantly down-regulated by (57.17±1.81)% ( t=3.179, P=0.043); compared with that in EV-LN229-RG cells, the PDCD10 expression in shPDCD10-LN229-RG cells was significantly down-regulated by (33.68±1.34)% ( t=3.085, P=0.045). (2) MTT assay showed that compared with the EV-U87-RG cells, the shPDCD10-U87-RG cells had significantly increased viability ( P<0.05); compared with the EV-T98g-RG cells, the shPDCD10-T98g-RG cells had significantly increased viability ( P<0.05). Among the same kind of cells, the viability 3 d after wash-out was significantly increased compared with that at 72 h after TMZ treatment ( P<0.05). Colony formation assay showed that cell lines with down-regulated PDCD10 expression had higher tumorigenic ability. (3) Compared with EV-U87-RG cells and EV-T98g-RG cells, cells with down-regulated PDCD10 expression (shPDCD10-U87-RG cells and shPDCD10-T98g-RG cells) escaped from TMZ-induced G2/M arrest, resulting in TMZ resistance. (4) Bioinformatics analysis revealed that the PDCD10 expression was positively correlated with MSH6 and PMS2 expressions ( r=0.262, P<0.001; r=0.327, P<0.001); qRT-PCR indicated that downregulated PDCD10 expression caused decreased MSH6 and PMS2 expressions, which disrupted the MMR system. (5) Compared with that by EV-U87 cells, number of neurospheres formed by shPDCD10-U87 cells was significantly increased ( P<0.05); compared with that by EV-U87-RG cells, number of neurospheres formed by shPDCD10-U87-RG cells was significantly increased ( P<0.05). Conclusion:PDCD10 affects the therapeutic sensitivity of GBM to TMZ by arresting cell cycle, disrupting MMR system, and increasing cell stemness.

No. II fluorocarbon blood substitute, also known as the PFC compound was injected intravenously into rats. Then the content of this compound in different tissues and oigans was determined at various intervals after the administration. It was found that the great majority of this compound was stored in the liver and spleen after its intravenous administration while only a small part was stored in the lungs and kidneys. As time went by, the amount stored in the tissues and organs would decrease. 90% of the PFC compound injected was eliminated out of the body in the eighth week after injection.When the gas chromatogram of PFC compound was compared with the standard one.no new peak on the spectrum was discovered. This fact indicates clearly that PFC compound is relatively inert, no changes of this compound occur in the body and it does not participate in the body metabolism.
