Objective To study effect of the antisense oligodeoxynucleotide (ASODN) of small subunit of human ribonucleotide reductase (RRM2) mRNA on cell line of human choriocarcinoma in vitro. Methods Two 20-mer gapmer ASODNs with a full phosphorothioate backbone were artificially synthesized, which were complementary to nucleotides 626-645 (a coding region) and 1572-1591 (a 3′untranslated region) of RRM2, respectively. ASODNs were transfected into JAR cells through oligofectamine. The survival rate was assessed by methyl thiazolyl tetrazolium (MMT) assay, and RRM2 expression was detected by immunoblot and reverse transcriptase polymerase chain reaction (RT-PCR) methods. Results Antisense oligodeoxynucleotide one (ASODN1) targeting the coding region significantly inhibited growth of JAR cells in a dose- and time-dependent manner and downregulated RRM2 expression in a time-dependent manner. ASODN1 at 100 nmol/L could inhibit significantly cell growth ( P =0.000), and the effects of ASODN1 on JAR cell proliferation were enhanced with increase of ASODN1 concentration and reached the peak point at 400 nmol/L concentration ( P =0.000). Cell growth was significantly inhibited by 200 nmol/L of ASODN1 after 24 h of treatment ( P =0.000). The effect of ASODN1 was at the maximum at 48 h ( P =0.000), and began to decrease at 72 h of treatment. RRM2 expression started to reduce after ASOND1 treatment for 12 hours, and was obviously downregulated at 24 h of treatment, and decreased to the lowest level at 48 h ( P

Objective To provide the theoretical supportting for targeted heparanase (HPA) inhibition of cervical cancer through observing the anti-proliferative effect of the HPA inhibitor on HeLa cell line of cervical cancer. Methods The two series of 13 kinds of novel HPA inhibitors were synthesized and optimized. Heparan degrading enzyme assay kit was used to test the effect of the inhibitors on the inhibition of HPA enzyme activity. Methyl thiazolyl tetrazolium (MTT) method and scratch test were used to observe the anti-proliferative and the migration effect of the inhibitors on HeLa cells. Flow cytometry was performed to determine the cell cycles and apoptosis. The expression of HPA was evaluated by reverse transcription (RT)-PCR, western blot and immunocytochemistry. Results All tested inhibitors could inhibit the activity of HPA enzyme [the range of 50% inhibiting concentration (IC50) values from 4.47 to 47.19 μmol/L] and the growth of HeLa cells (the range of IC50 values from 48.16 to 96.64μmol/L). Among them, No.16 compound exhibits the strongest inhibition against the growth of HeLa, which could arrest the cell into G0/G1 and G2/M phases. The rate of cell apoptosis in the group treated with 50μmol/L No.16 for 48 hours [(11.9±1.2)%] was significantly higher than that [(6.6 ± 1.8)%] in untreated group (P=0.013). Real time PCR and western blot showed that expression levels of HPA mRNA (1.23±0.46) and protein (0.46±0.31) significantly decreased in the treated group as compared with the levels of HPA mRNA (3.43 ± 0.45) and protein (1.30 ± 0.58) in the untreated group (both P<0.05). Immunocytochemistry also showed that the treatment of No.16 significantly reduced the average optical density (0.39 ± 0.04) of HPA immuostaining signal compared with that in the control group (0.50 ± 0.09; P=0.026). Conclusion Novel 1,3-O,N spiroheterocyclic HPA inhibitors could inhibit the proliferation of HeLa cells,inhibit the HPA enzyme activity in different degree, and down-regulate the expression of HPA protein.

Objective To explore the role of σ1 receptor (σ1R) in the clinical prognosis of cervical cancer,and provide a theoretical basis for σ1R targeted molecular therapy through observing the inhibition of synthetic σ1R-specific ligand compounds on the growth of cervical cancer cells. Methods (1) Immunohistochemical or immunocytochemistry staining were respectively used to detect the expression and localization of σ1R protein.(2)The Cancer Genome Atlas (TCGA) data set was used to validate our results. (3)Two series of 4 novel σ1R ligand compounds were synthesized by altering the N-terminal substituents on the piperidine ring of the prezamicol analogue, named as 14a, 14e, 15c and 15f. Methyl thiazolyl-tetrazolium (MTT) assay was detect the anti-proliferative effect of the four compounds on HeLa and SiHa cells. Compound 14a with potent inhibitory activity and the highest specificity of σ1R was selected for further experiments. Scratch test was observed the migration effect of compound 14a on HeLa and SiHa cells. Flow cytometry was determined cell cycles and apoptosis. Results (1) Immunostaining of σ1R protein was located in the cytoplasm and nucleus of cervical epithelium. The expression of cervical squamous cell carcinoma (SCC) was significantly higher than those of high-grade squamous intraepithelial lesion (HSIL) or normal cervical tissues. There was no significant difference in the expression of σ1R between HSIL and normal cervical tissues. σ1R expression in cervical adenocarcinoma (AC) was higher than that in SCC (P=0.020). The nuclear expression rate of σ1R in AC (10/18) was higher than that of SCC (27.1%, 19/70; P=0.024). The median overall survival (MOS) of σ1R-positive SCC patients was lower than that of σ1R-negative patients [(45.8±3.1) vs (51.7±2.9) months, P=0.045]. MOS of the patients with σ1R nuclear positive SCC was lower than that of non-nuclear staining [(38.9±3.8) vs (48.7±2.1) months, P=0.022]. MOS of the patients with σ1R nuclear positive AC was lower than that of non-nuclear staining [(35.0± 6.3) vs (44.2±4.2) months, P=0.034]. (2) Analysis of TCGA data showed that σ1R expression of in SCC was correlated with age (P=0.005). σ1R expression in AC was significantly associated with advanced stage, lymphnode metastasis and vascular invasion (all P<0.05). MOS of AC patients with σ1R overexpression was significantly lower than that of the patients with low expression (P=0.034). There was no significant difference in the MOS of different expression of σ1R mRNA in SCC patients(P=0.930). (3) MTT assay showed that these four compounds could suppressed the growth of HeLa and SiHa cells in time- and dose-dependent manner. The growth inhibition rates of HeLa and SiHa cells at 48 hours treated by combination of different concentrations of nedaplatin (NDP) with compound 14a (6 μmol/L) were significantly higher than those treated by NDP alone. Compound 14a (30 μmol/L) significantly inhibited the migration (both P<0.01) and induced the apoptosis of HeLa or SiHa cells (both P<0.01). Conclusions σ1R is over-expressed in cervical cancer and HSIL. σ1R nuclear expression is an important marker of AC. σ1R over-expression, especially σ1R nuclear expression is associated with the poor prognosis of cervical cancer. Our study is mostly consistent with cervical cancer data of TCGA. These results suggest that the novel synthetic prezamicol analogues 14a for σ1R could inhibit the growth of cervical cancer cells and cell migration through inducing apoptosis and arresting cell cycle in G0/G1 period, enhance NDP-induced cytotoxicity.

OBJECTIVE:
To explore the genetic basis of a fetus with enlargement and enhanced echo of the kidneys.
METHODS:
The imaging data of the fetus were collected, in addition with 20 mL amniotic fluid sample and 2 mL peripheral blood samples of both parents. Amniotic DNA was extracted for library construction and whole exome sequencing, and Sanger sequencing was carried out to verify candidate variant associated with the fetal phenotype.
RESULTS:
Prenatal ultrasound showed that the fetus had enlargement and enhanced echo of the kidneys, in addition with many small renal cysts. Whole exome sequencing showed that the fetus carried pathogenic compound heterozygous variants of the ETFDH gene, namely c.3G>C and c.1436dupA. Sanger sequencing of the family suggested that the variants were inherited from its mother and father, respectively.
CONCLUSION
By combining its clinical manifestations and results of whole exome sequencing, the fetus was diagnosed as glutaric acidemia type ⅡC due to the compound heterozygous variants of the ETFDH gene. Above results have provided a basis for prenatal diagnosis and genetic counseling. Fetal exome sequencing has provided an important tool for prenatal diagnosis.
