ABSTRACT

ObjectiveTo investigate the expression of RNA binding motif single stranded interacting protein 3 (RBMS3) in epithelial ovarian cancer (EOC) tissues and its relationship with the clinicopathological features and prognosis of EOC. MethodsThe study enrolled the paraffin-embedded tissues from 110 EOC cases and 73 benign epithelial ovarian tumor cases pathologically diagnosed in the first affiliated Hospital of Bengbu Medical College from January 2015 to December 2019. By using anti-RBMS3 polyclonal antibody, the immunohistochemical staining was employed to detect RBMS3 expression in the tissues and then its correlation with the clinicopathological parameters and prognosis of EOC was analyzed. ResultsRBMS3 was expressed in both EOC and benign epithelial ovarian tumor tissues. RBMS3 expression in EOC tissues, significantly related with International Federation of Gynecology and Obstetrics (FIGO) stage, histological grade, CEA levels and survival status, was significantly lower than that in benign epithelial ovarian tumor tissues (P<0.05). Kaplan–Meier survival curve showed that low RBMS3 expression in EOC patients was correlated with decreased progression-free survival (PFS) and overall survival (OS) (P<0.05). Univariate analysis showed that RBMS3 expression, FIGO stage, residual lesion size, intestinal metastasis and intraperitoneal implantation were associated with OS of EOC patients (P<0.05); multivariate analysis showed that low RBMS3 expression and intestinal metastasis were independent risk factors for poor prognosis in EOC patients (P<0.05). ConclusionsRBMS3 is expressed at low levels in EOC tissues, which is closely related to poor prognosis of EOC patients. RBMS3 may function as a tumor suppressor gene in EOC tissues and can be used as an EOC-independent prognostic marker for targeted therapy against EOC.

ABSTRACT

Tumor microenvironment (TME) is composed of endothelial cells, pericytes, immune cells, cancer-associated fibroblasts (CAFs), cancer stem cells (CSCs), extracellular matrix (ECM) and other components of the complex biological environment. TME interacts with the tumor cells through a large amount of signaling pathways, participates in the process of tumor progression, invasion, and metastasis. Hence, TME has become a potential therapeutic target for cancer treatment, exhibiting excellent therapeutic potential and research value in the field of cancer treatment. Currently, the novel nanotechnology has been widely applied in anticancer therapy, and nanotechnology-mediated drug delivery system is being explored to apply in TME modulation to inhibit tumor progression. Nanotechnology-mediated drug delivery has many advantages over traditional therapeutic modalities, including longer circulation times, improved bioavailability, and reduced toxicity. This review summarized the research of targeted nano-drug delivery based on TME regulation, including regulation strategies based on CSCs, CAFs, immune cells, ECM, tumor vascularization, exosomes, and microbiota. In addition, we summarized the advantages, opportunities, and challenges of TME regulation strategy compared with traditional treatment strategy, which provides a reference for the application of nano-drug delivery system based on TME regulation strategy in tumor precision therapy.

ABSTRACT

@#【Objective】To investigate the mechanism of action of long non-coding RNA highly up-regulated in liver cancer(LncRNA HULC)on the growth of glioblastoma U87 cells in vitro and in vivo.【Methods】The cultured glioblastoma U87 cells were divided into four groups:overexpression group(HULC-over)and its vector control group(VEC),silent expression group(HULC- siRNA)and its negative control group(NC).Quantitative real- time polymerase chain reaction PCR(qRT-PCR)was used to verify the expression levels of HULC. CCK8 proliferation assay and colony formation assay were adopted to monitor the proliferation of glioblastoma U87 cells. Flow cytometry was utilized to detect the apoptosis of glioblastoma U87 cells. By injecting U87 cells,we divided the orthotopic xenograft mouse model into HULC- over group(n=10),VEC group(n=10),HULC-siRNA group(n=10)and NC group(n=10)accordingly. The survival of the mice in each group was observed. The expression of Ki67 was analyzed by immunohistochemistry. 【Results】 The expression level of HULC was significantly higher in HULC-over group than that in VEC group and significantly lower in HULC-siR NA group than that in NC group(P < 0.01). The cell proliferation ability was significantly increased in HULC-over group compared with that in VEC group and significantly decreased in HULC- siRNA group compared with that in NC group(P < 0.01 on days2,3and4). The colony formation rates in VEC group,HULC-over group,NC group and HULC-siRNA group were,respectively,(34.47 ± 1.56)% ,(95.4 ± 2.74)% ,(23.83 ± 0.92)% and (10.23 ± 0.61)% ,which revealed that overexpression of HULC elevated the colony formation rate and silencing expression of HULC reduced the colony formation rate(P < 0.01). The early apoptosis rates in VEC group,HULC- over group,NC group and HULC- siRNA group were,respectively,(3.55±0.56)% ,(0.09±0.01)% ,(2.89±0.67)% ,and(7.13±0.14)% ,which showed that overexpression of HULC elevated the early apoptosis rate and silencing expression of HULC reduced the early apoptosis rate (P <0.01). The survival curve of nude mouse indicated shorter survival time in HULC-over group than that in VEC group and longer survival time in HULC-siRNA group than that in NC group(P < 0.05). Ki67 protein expression was up-regulated in the HULC-over group compared with that in VEC group and down-regulated in the HULC-siRNA group compared with that in NC group(P < 0.05).【Conclusion】LncRNA HULC can enhance the growth of glioblastoma U87 cells in vitro and in vivo.

ABSTRACT

@#【Objective】 To explore the effects of long- chain non- coding RNA highly up- reglated in liver cancer(LncRNA HULC)silencing expression on proliferation and apoptosis of human glioblastoma cell line SHG44.【Methods】 Quantitative Real- time Polymerase Chain Reaction (qRT- PCR) was used to verify the expression level of HULC in HULC silent expression group (HULC- siRNA)and negative control group (NC group). CCK8 proliferation assay and plate colony formation assay were used to detect the proliferation of glioblastoma cells. Cell cycle and apoptosis assays were used to detect the cell cycle distribution and apoptosis of glioblastoma cells. 【Results】 qRT- PCR confirmed that HULC- siRNA group had significantly lower expression of HULC than NC group (P=0.003). CCK8 proliferation experiment showed that the proliferation rate of HULC-siRNA group was significantly lower than that of NC group on the second,third and fourth days of experiment(Day 2,P=0.003;Day 3,P=0.005;Day 4,P=0.009). Plate colony formation assay showed the cloning rates in the NC and HULC-siRNA groups were(34.11 ± 1.24)% and(14.44 ± 0.87)%,and it showed that the cell clone formation rate was clearly decreased after silenced expression of HULC (P<0.001). The cell cycle assay showed that the numbers of cells in NC group and HULC-siRNA group were G1 phase(36.89 ± 4.09,51.74± 0.68)and S phase(46.95 ± 2.49,36.89 ± 2.13),and it showed that the cell cycle was blocked in G1/S phase after silencing HULC expression (G1 phase,P=0.023,S phase,P=0.038). Apoptosis experiment showed that the early apoptotic rates of NC group and HULC-siRNA group were(2.57 ± 0.22)% and(7.063 ± 0.71)%,and it showed that the early apoptotic rate of the cells was significantly increased after silencing HULC expression (P=0.004). 【Conclusion】 Silencing of LncRNA HULC can inhibit the proliferation of glioblastoma cells and promote their apoptosis.
