Abstract
Propofol is an important and widely used anaesthetic drug in the clinic. Many works have shown that propofol has important biological functions except as an anaesthetic. In the current study, we mainly explored the effect of propofol on the biological activity of IGF-1, which is an important growth factor involved in regulating the growth and development of the stomach. Here, we explored the effect of propofol on the biological activity of IGF-1 in a GES-1-cell model. We found that propofol affected the biological activity of IGF-1. It not only reduces IGF-1/IGF-1R signalling but also changes IGF-1R cell characteristics. We further explored the mechanism by which propofol affected IGF-1 activity. Through a series of experiments, we found that propofol affected the stability of membrane-localised IGF-1R. It also affects the recycling of the IGF-1R receptor Propofol can affect the degradation of IGF-1R by changing the endocytosis of IGF-1R. In short, the current study found that propofol affected the biological activity of IGF-1, which laid the foundation for related research.

Abstract
Breast cancer is the most common malignancy affecting women worldwide. The insulin-like growth factor 1 (IGF-1) gene encodes a protein responsible for a wide variety of physiological processes, including differentiation and cell proliferation. Despite several studies on tumor tissues, no study has evaluated IGF-1 expression in the peripheral blood of women with recurrent breast cancer.In this cross-sectional study, IGF-1 expression in the peripheral blood of 146 women with breast cancer treated approximately 5 years ago was quantified by quantitative reverse transcription polymerase chain. The women were divided into 2 groups: non-recurrence (n = 85) and recurrence (n = 61). Statistical analysis of the data was performed using ANOVA, Mann-Whitney, and Chi-squared tests (P < .05).The results showed no significant difference in IGF-1 expression between the non-recurrence and recurrence groups (P = .988). In the subgroups of patients with lymph node involvement, no statistically significant difference was observed in IGF-1 expression between women with recurrence and those non-recurrence (P = .113). In patients without lymph node metastases, IGF-1 messenger ribonucleic acid (mRNA) expression levels were significantly higher in the non-recurrence group than in the recurrence group (P = .019). Furthermore, using the median IGF-1 mRNA expression as the cutoff point, it was obtained a statistically significant difference in tumor histological grade among women with recurrent breast cancer (P = .042).These data showed significantly higher IGF-1 expression in women without lymph node metastases in the non-recurrence group compared with the recurrence group. In addition, a significant difference was observed in median IGF-1 mRNA expression in relation to tumor histological grade in women with recurrent breast cancer.

Abstract
MicroRNAs (miRs), a class of non-coding RNAs that are 18–25 nucleotides in length, serve as key regulators in the development and progression of human cancers. Previously, miR-503 has been implicated in breast cancer. However, the underlying mechanism of miR-503 in regulating the proliferation and invasion of breast cancer cells remains largely unknown. In the present study, reverse transcription-quantitative polymerase chain reaction analysis indicated that the expression of miR-503 was significantly reduced in breast cancer tissues compared with their matched adjacent normal tissues. Furthermore, miR-503 expression levels were markedly reduced in T2-T4 stage breast cancer, compared with T1 stage. Insulin-like growth factor 1 receptor (IGF-1R) was further identified as a novel target of miR-503. Overexpression of miR-503 significantly suppressed the protein expression levels of IGF-1R. Furthermore, it inhibited the proliferation and invasion of human breast cancer MCF-7 cells, as assessed by MTT and Transwell assays, respectively. However, restoration of IGF-1R expression markedly ameliorated the suppressive effects of miR-503 overexpression on MCF-7 cell proliferation and invasion, indicating that miR-503 inhibits breast cancer cell proliferation and invasion at least partially via directly targeting IGF-1R. Furthermore, the mRNA and protein expression levels of IGF-1R were demonstrated to be significantly increased in breast cancer tissues compared with their matched adjacent normal tissues. In addition, IGF-1R mRNA expression levels were reversely correlated with miR-503 expression levels in breast tumors, suggesting that the upregulation of IGF-1R may be due to downregulation of miR-503 in breast cancer. In conclusion, the present study expanded the understanding of the regulatory mechanism of miR-503 in breast cancer, and implicates the miR-503/IGF-1R axis as a potential therapeutic target for breast cancer.

Increased insulin-like growth factor-1 receptor mRNA expression predicts poor survival in immunophenotypes of early breast carcinoma. Mod Pathol 2011; 24:201-8.

Abstract
The biology of breast carcinoma shows a great variation, reflected by the recent classification of phenotypes based on DNA microarrays or immunohistochemistry. The aim of this study was to determine the prevalence of insulin-like growth factor-1 receptor (IGF1R) in breast carcinoma subtypes and the impact on the outcome. We studied 197 consecutive breast carcinoma patients in stage I-II treated conservatively. Phenotypes were assessed on the basis of the expressions of ER/PR, HER2, Ki67, p53, Bcl2, CK5/6 and EGFR. Moreover, IGF1R expression (α-subunit and β-phosphorylated/active form) was evaluated by immunohistochemistry, IGF1R mRNA levels by quantitative RT-PCR and IGF1R mutations by direct DNA sequencing. Overall, 40% (78/197) of tumors were luminal A, 24% (48/197) luminal B, 19% (37/197) HER2-positive and 17% (34/197) basal/triple-negative. Luminal A tumors were predominantly of low grade, without necrosis, presenting in older patients as a ≤2-cm unilateral mass (all P ≤ 0.046). α-IGF1R overexpression was observed more frequently in luminal A (49%) cases, followed by luminal B (20%), HER2-positive area under the curve (22%) and basal/triple-negative cases (9%) (P = 0.01) with similar results for mRNA levels (53, 24, 13 and 10%, respectively) (P = 0.038), but without differences for mutations (P = NS). High IGF1R mRNA correlated with poor patient survival among subtypes (P = 0.004) (Kaplan-Meier; log-rank test). For overall survival, only histological grade and IGF1R mRNA emerged as significant predictors (P ≤ 0.034; Cox regression). Increased IGF1R mRNA implies poorer patient prognosis among the different subtypes, and that may be associated with the lack of responsiveness to tamoxifen in cases with a positive hormone receptor status. Our results highlight the biological and clinical relevance of IGF1R in early breast carcinoma subtypes, and provide knowledge to assist in treatment decision.

Abstract
The type 1 insulin-like growth factor receptor (IGF-1R) is essential for tumorigenicity, tumor proliferation, and protection from apoptosis. IGF-1R overexpression has been found in many human cancers including osteosarcoma. To explore its possibility as a therapeutic target for the treatment of osteosarcoma, lentivirus-mediated siRNA was employed to downregulate endogenous IGF-1R expression to study the function of IGF-1R in tumorigenesis and radioresistance of osteosarcoma cells. The IGF-1R expression was persistently and markedly reduced by lentivirus-mediated RNAi. Downregulation of IGF-1R expression in osteosarcoma cells significantly suppressed their growth rates in vitro and reduced the potential of tumorigenicity in vivo. Moreover, the specific downregulation arrested cells in G(0)/G(1) phase of cell cycle and also induced apoptosis which correlated with the activation of Caspase-3. Furthermore, we also observed that suppression of IGF-1R could reduce the invasiveness of osteosarcoma cells and enhance their radiosensitivity. Our study suggested that lentivirus-mediated RNAi silencing targeting IGF-1R could induce potent antitumor activity and radiosensitizing activity in human osteosarcomas.

Abstract
Background The predictive value of IGF1R on local recurrence in invasive breast carcinoma (BC) is not well known. Methods In a series of 197 lymph-node negative BC patients treated with breast-conserving surgery and radiation therapy, we performed immunohistochemistry for alpha-IGF1R, beta-IGF1R (phosphorylated/active form) and Estrogen/Progesterone receptors. We further evaluated the IGF1R mRNA expression by quantitative RT-PCR and IGF1R mutations by direct DNA sequencing (exons 19 and 21) in 85 primary BC (42 control cases, 31 with local recurrence and 12 with distant metastasis) and in 31 local recurrences. Unconditional logistic regression analyses were performed to identify risk factors for recurrence. Results Local recurrences were associated with high-grade tumors, PR-negative and low active-IGF1R, which emerged as independent breast relapse predictors by multivariate analysis. Conclusion Patients with early BC treated with lumpectomy and radiation who have low-grade tumors and favorable markers (increased content of active IGF1R and PR-positive) have a low risk of local recurrence. Therefore, do not benefit from a boost dose on the surgical scar.
