Abstract
Inevitable emergence of acquired resistance to EGFR TKIs including third-generation TKI osimertinib limits their long-term efficacy in treating EGFR-mutant lung cancer. A fuller investigation of novel molecular mechanisms underlying acquired resistance is essential to develop efficacious therapeutic strategies. Consequently, we have identified a novel TGFβ1/integrin β3 loop that contributes to the occurrence of EGFR TKI-acquired resistance. EGFR TKIs dramatically and sustainably increased the expression of both TGFβ1 and integrin β3 in in vitro and in vivo EGFR-mutant lung cancer models with acquired resistance to EGFR TKIs. Previously, we reported that integrin β3 expression was partially induced by TGFβ1 in these models. Moreover, elevated TGFβ1 in these models was secreted mostly from lung cancer cells. Mechanistically, TGFβ1 was induced and activated by overexpressed integrin β3, forming a positive feedback loop. More importantly, the interruption of TGFβ1/integrin β3 positive feedback loop was shown to dramatically delay the occurrence of acquired resistance and greatly improve the efficacy of EGFR TKI in treating EGFR-mutant lung cancer. Taken together, our study first demonstrated the TGFβ1/integrin β3 loop a new mechanism and target for acquired EGFR TKI resistance in EGFR-mutant lung cancer.

Abstract
INTRODUCTION Activin A has been widely regarded as an important promoter of trophoblast invasion during the first trimester of pregnancy. However, whether integrin β3 is involved in activin A-upregulated trophoblast invasion and the underlying molecular mechanisms remain largely unknown. METHODS We utilized immortalized (HTR8/SVneo) and primary human extravillous trophoblast (EVT) cells, as well as first-trimester chorionic villous explants as study models to investigate the function and underlying molecular mechanisms of integrin β3 in activin A-promoted human trophoblast invasion. RESULTS We found that activin A increased integrin β3 mRNA and protein levels in both HTR8/SVneo and primary EVT cells, and knockdown of integrin β3 significantly decreased basal and activin A-upregulated trophoblast invasion. Moreover, SB431542 (a specific inhibitor of TGF-β type Ι receptor kinase) abolished activin A-upregulated integrin β3 expression and SMAD2/3 phosphorylation. In addition, siRNA-mediated knockdown of ALK4 or SMAD4 both abolished activin A-upregulated integrin β3 expression in HTR8/SVneo cells, while knockdown of ALK4 or SMAD4 attenuated activin A-upregulated integrin β3 expression in primary EVTs. DISCUSSION Our findings reveal the mediation role of integrin β3 in activin A-upregulated human trophoblast invasion and that activin An upregulates integrin β3 expression in an ALK4-SMAD4 signaling-dependent manner.

Abstract
Abstract Constructing bionic extracellular matrix (ECM) is an attractive proposition for tissue engineering and clinical regeneration therapy involving the stemness of stem cells. Here, a novel recombinant protein fibronectin-collagen peptide (FCP) was designed to modulate the function of ECM expressed by Picha. pastoris strain X33. This FCP promotes cell migration and adhesion and maintains rBMSC stemness by binding integrin β3. Its effects were blocked by both integrin β3 siRNA and the integrin β3 inhibitor Cilengitide. A template-independent ab initio prediction modeling approach is the best approach to construct a stable FCP protein model, which predicts the binding sites between FCP and integrin β3. FCP may be used in the in vitro culture and clinical regeneration of stem cells that highly express integrin β3, such as hematopoietic stem cells. The study provides information on the molecular structure of FCP and its bioactivity, which can be used to design new compounds. Key points • Design a novel recombinant fibronectin-collagen peptide biomimetic ECM. • FCP promotes cell adhesion, migration, and proliferation. • Predicted and verified FCP structure and affinity with integrin β3. • FCP binds integrin β3 to maintain rBMSC stemness.

Abstract
Pulmonary fibrosis is a progressive disease with poor prognosis and limited therapeutic options. In this study, we evaluated the potential therapeutic effects of CG223, a novel inhibitor of bromodomain and extra-terminal motif (BET) proteins, on pulmonary fibrosis by focusing on the transforming growth factor-β1 (TGF-β1) pathway. In a murine model of bleomycin-induced pulmonary fibrosis, CG223 attenuated fibrosis while reducing the infiltration of inflammatory cells into the lungs. Fibroblasts expressing BRD4, a member of the BET protein family, were enriched in the tissue regions corresponding to bleomycin-induced fibrotic lesions. Additionally, pulmonary fibroblasts isolated from bleomycin-instilled mice showed a significantly increased association of BRD4 with the promoters of two pro-fibrotic genes linked to the entry into the TGF-β1 autocrine/paracrine loop, thrombospondin 1 (Thbs1) and integrin β3 (Itgb3), as well as with the promoter of a myofibroblast marker gene, actin alpha 2 (Acta2). Subsequent in vitro studies with murine primary lung fibroblasts showed that the mRNA induction of Thbs1, Itgb3, and Acta2 by TGF-β1 can be inhibited by CG223 in a dose-dependent manner. Taken together, CG223-induced BRD4 inhibition suppressed lung fibrogenesis by affecting multiple genes, including those involved in the triggering of the TGF-β1 autocrine/paracrine loop.

Abstract
Dysfunctional dendritic arborization is a key feature of many developmental neurological disorders. Across various human brain regions, basal dendritic complexity is known to increase along a caudal-to-rostral gradient. We recently discovered that basal dendritic complexity of layer II/III cortical pyramidal neurons in the mouse increases along a caudomedial-to-rostrolateral gradient spanning multiple regions, but at the time, no molecules were known to regulate that exquisite pattern. Integrin subunits have been implicated in dendritic development, and the subunit with the strongest associations with autism spectrum disorder and intellectual disability is integrin β3 (Itgb3). In mice, global knockout of Itgb3 leads to autistic-like neuroanatomy and behavior. Here, we tested the hypothesis that Itgb3 is required for increasing dendritic complexity along the recently discovered tangential gradient among layer II/III cortical pyramidal neurons. We targeted a subset of layer II/III cortical pyramidal neurons for Itgb3 loss-of-function via Cre-loxP-mediated excision of Itgb3. We tracked the rostrocaudal and mediolateral position of the targeted neurons and reconstructed their dendritic arbors. In contrast to controls, the basal dendritic complexity of Itgb3 mutant neurons was not related to their cortical position. Basal dendritic complexity of mutant and control neurons differed because of overall changes in branch number across multiple branch orders (primary, secondary, etc.), rather than any changes in the average length at those branch orders. Furthermore, dendritic spine density was related to cortical position in control but not mutant neurons. Thus, the autism susceptibility gene Itgb3 is required for establishing a tangential pattern of basal dendritic complexity among layer II/III cortical pyramidal neurons, suggesting an early role for this molecule in the developing brain.

Abstract
Porcine reproductive and respiratory syndrome virus (PRRSV) is the pathogen of porcine reproductive and respiratory syndrome (PRRS), which is one of the most economically harmful diseases in modern pig production worldwide. Receptor of activated protein C kinase 1 (RACK1) was previously shown to be indispensable for the PRRSV replication and NF-κB activation in Marc-145 cells. Here we identified a membrane protein, integrin β3 (ITGB3), as a RACK1-interacting protein. PRRSV infection in Marc-145 cells upregulated the ITGB3 expression. Abrogation of ITGB3 by siRNA knockdown or antibody blocking inhibited PRRSV infection and NF-κB activation, while on the other hand, overexpression of ITGB3 enhanced PRRSV infection and NF-κB activation. Furthermore, inhibition of ITGB3 alleviated the cytopathic effects and reduced the TCID50 titer in Marc-145 cells. We also showed that RACK1 and ITGB3 were NF-κB target genes during PRRSV infection, and that they regulated each other. Our data indicated that ITGB3, presumably as a co-receptor, played an imperative role during PRRSV infection and NF-κB activation in Marc-145 cells. PRRSV infection activates a positive feedback loop involving the activation of NF-κB and upregulation of ITGB3 and RACK1 in Marc-145 cells. The findings would advance our elaborated understanding of the molecular host-pathogen interaction mechanisms underlying PRRSV infection in swine and suggest ITGB3 and NF-κB signaling pathway as potential therapeutic targets for PRRS control.

Abstract
Background Ovarian cancer is the third most common cause of death among gynecologic malignancies worldwide. Understanding the biology and molecular pathogenesis of ovarian epithelial tumors is key to developing improved prognostic indicators and effective therapies. We aimed to determine the effects of PAX8 expression on the migrative, adhesive and survival capabilities of high-grade serous carcinoma cells. Methods PAX8 depleted Fallopian tube secretory cells and ovarian cancer cells were generated using short interfering siRNA. Anoikis resistance, cell migration and adhesion properties of PAX8 silenced cells were analyzed by means of specific assays. Chromatin immunoprecipitation (ChIP) was carried out using a PAX8 polyclonal antibody to demonstrate that PAX8 is able to bind to the 5′-flanking region of the ITGB3 gene positively regulating its expression. Results Here, we report that RNAi silencing of PAX8 sensitizes non-adherent cancer cells to anoikis and affects their tumorigenic properties. We show that PAX8 plays a critical role in migration and adhesion of both Fallopian tube secretory epithelial cells and ovarian cancer cells. Inhibition of PAX8 gene expression reduces the ability of ovarian cancer cells to migrate and adhere to the ECM and specifically to fibronectin and/or collagen substrates. Moreover, loss of PAX8 strongly reduces ITGB3 expression and consequently the correct expression of the αvβ3 heterodimer on the plasma membrane. Conclusions Our results demonstrate that PAX8 modulates the interaction of tumor cells with the extracellular matrix (ECM). Notably, we also highlight a novel pathway downstream this transcription factor. Overall, PAX8 could be a potential therapeutic target for high-grade serous carcinoma.

Abstract
Cellular Senescence is associated with organismal aging and related pathologies. Previously, we reported that plasminogen activator inhibitor-1 (PAI-1) is an essential mediator of senescence and a potential therapeutic target for preventing aging-related pathologies. In this study, we investigate the efficacies of PAI-1 inhibitors in both in vitro and in vivo models of homocysteine (Hcy)-induced cardiovascular aging. Elevated Hcy, a known risk factor of cardiovascular diseases, induces endothelial senescence as evidenced by increased senescence-associated β-Gal positivity (SA-β-Gal), flattened cellular morphology, and cylindrical appearance of cellular nuclei. Importantly, inhibition of PAI-1 by small molecule inhibitors reduces the number of SA-β-Gal positive cells, normalizes cellular morphology and nuclear shape. Furthermore, while Hcy induces the levels of senescence regulators PAI-1, p16, p53 and integrin β3, and suppresses catalase expression, treatment with PAI-1 inhibitors blocks the Hcy-induced stimulation of senescence cadres, and reverses the Hcy-induced suppression of catalase, indicating that PAI-1 specific small molecule inhibitors are efficient to prevent Hcy-induced cellular senescence. Our in vivo study shows that the levels of integrin β3, a recently identified potential regulator of cellular senescence, and its interaction with PAI-1 are significantly elevated in Hcy-treated heart tissues. In contrast, Hcy suppresses antioxidant gene regulator Nrf2 expression in hearts. However, co-treatment with PAI-1 inhibitor completely blocks the stimulation of Hcy-induced induction of integrin β3 and reverses Nrf2 expression. Collectively these in vitro and in vivo studies indicate that pharmacological inhibition of PAI-1 improves endothelial and cardiac health by suppressing the pro-senescence effects of hyperhomocysteinemia through suppression of Hcy-induced master regulators of cellular senescence PAI-1 and integrin β3. Therefore, PAI-1 inhibitors are promising drugs for amelioration of hyperhomocysteinemia-induced vascular aging and aging-related disease.

Abstract
Metastasis is the leading cause of breast cancer-related deaths. Cancer-associated fibroblasts (CAFs), the predominant stromal cell type in the breast tumour microenvironment, may contribute to cancer progression through interaction with tumour cells. Nonetheless, little is known about the details of the underlying mechanism. Here we found that interaction of interleukin 32 (IL32) with integrin β3 (encoded by ITGB3; a member of the integrin family) mediating the cross-talk between CAFs and breast cancer cells plays a crucial role in CAF-induced breast tumour invasiveness. IL32, an 'RGD' motif-containing cytokine, was found to be abundantly expressed in CAFs. Integrin β3 turned out to be up-regulated in breast cancer cells during epithelial-mesenchymal transition (EMT). CAF-derived IL32 specifically bound to integrin β3 through the RGD motif, thus activating intracellular downstream p38 MAPK signalling in breast cancer cells. This signalling increased the expression of EMT markers (fibronectin, N-cadherin, and vimentin) and promoted tumour cell invasion. Counteracting IL32 activity, a knockdown of IL32 or integrin β3 led to specific inactivation of p38 MAPK signalling in tumour cells. Blockage of the p38 MAPK pathway also diminished IL32-induced expression of EMT markers and breast cancer cell invasion and metastasis. Thus, our data indicate that CAF-secreted IL32 promotes breast cancer cell invasion and metastasis via integrin β3-p38 MAPK signalling.

Abstract
BACKGROUND/AIMS Neointimal hyperplasia is responsible for stenosis, which requires corrective vascular surgery, and is also a major morphological feature of many cardiovascular diseases. This hyperplasia involves the endothelial-to-mesenchymal transition (EndMT). We investigated whether integrin β3 can modulate the EndMT, as well as its underlying mechanism. METHODS Integrin β3 was overexpressed or knocked down in human umbilical vein endothelial cells (HUVECs). The expression of endothelial markers and mesenchymal markers was determined by real-time reverse transcription PCR (RT-PCR), immunofluorescence staining, and western blot analysis. Notch signaling pathway components were detected by real-time RT-PCR and western blot analysis. Cell mobility was evaluated by wound-healing, Transwell, and spreading assays. Fibroblast-specific protein 1 (FSP-1) promoter activity was determined by luciferase assay. RESULTS Transforming growth factor (TGF)-β1 treatment or integrin β3 overexpression significantly promoted the EndMT by downregulating VE-cadherin and CD31 and upregulating smooth muscle actin α and FSP-1 in HUVECs, and by enhancing cell migration. Knockdown of integrin β3 reversed these effects. Notch signaling was activated after TGF-β1 treatment of HUVECs. Knockdown of integrin β3 suppressed TGF-β1-induced Notch activation and expression of the Notch downstream target FSP-1. CONCLUSION Integrin β3 may promote the EndMT in HUVECs through activation of the Notch signaling pathway.

Abstract
Preeclampsia is a serious pregnancy complication associated with placental oxidative stress and impaired trophoblast migration. The mechanism of defective trophoblast migration remains unknown. Forkhead box O1 (FOXO1) is a transcription factor. Integrin β3 is involved in cell motility. We hypothesized that FOXO1 mediates expression of trophoblast integrin β3, which could be impaired by oxidative stress and have implications in preeclampsia. The expressions of FOXO1 and integrin β3 were significantly reduced in preeclamptic placentas (n = 15) compared to that of controls (n = 15; p < 0.01). HTR-8/SVneo and JEG-3 trophoblasts were transfected to express wild-type FOXO1-WT or constitutively-expressed nuclear mutant form, FOXO1-AAA. The FOXO1 in HTR-8/SVneo and 3A-Sub-E trophoblasts was silenced by small interfering RNA. AKT-mediated phosphorylation inactivated FOXO1, but FOXO1-AAA was not phosphorylated. The expression of trophoblast integrin β3 was significantly elevated by FOXO1 overexpression and inhibited by FOXO1 knockdown. FOXO1 regulates integrin β3 at the transcriptional level via binding to the putative FOXO1 response element site between position -1154 to -1139 (TGAGATGTTTTGAAAG) in HTR-8/SVneo trophoblasts. The level of phosphorylated FOXO1 was decreased, and the FOXO1 level was increased in trophoblasts treated with AKT inhibitor MK2206, leading to upregulation of integrin β3. The capabilities of trophoblast adhesion and migration were enhanced by FOXO1-overexpression or MK2206, and inhibited by silencing FOXO1 or oxidative stress with H2O2. These results suggest that FOXO1 enhances trophoblast integrin β3 expression, and mediates cell adhesion and migration. By affecting the expression of FOXO1 and cell motility in trophoblasts, oxidative stress plays a role in the development of preeclampsia.

Abstract
BACKGROUND/AIMS Homeobox D3 (HOXD3) is a member of the homeobox family of genes that is known primarily for its transcriptional regulation of morphogenesis in all multicellular organisms. In this study, we sought to explore the role that HOXD3 plays in the stem-like capacity, or stemness, and drug resistance of breast cancer cells. METHODS Expression of HOXD3 in clinical breast samples were examined by RT-PCR and immunohistochemistry. HOXD3 expression in breast cancer cell lines were analyzed by RT-PCR and western blot. Ability of drug resistance in breast cancer cells were elevated by MTT cell viability and colony formation assays. We examined stemness using cell fluorescent staining, RT-PCR and western blot for stem cell marker expression. Finally, activity of wnt signaling was analyzed by FOPflash luciferase assays. RT-PCR and western blot were performed for downstream genes of wnt signaling. RESULTS We demonstrated that HOXD3 is overexpressed in breast cancer tissue as compared to normal breast tissue. HOXD3 overexpression enhances breast cancer cell drug resistance. Furthermore, HOXD3 upregulation in the same cell lines increased sphere formation as well as the expression levels of stem cell biomarkers, suggesting that HOXD3 does indeed increase breast cancer cell stemness. Because we had previously shown that HOXD3 expression is closely associated with integrin β3 expression in breast cancer patients, we hypothesized that HOXD3 may regulate breast cancer cell stemness and drug resistance through integrin β 3. Cell viability assays showed that integrin β 3 knockdown increased cell viability and that HOXD3 could not restore cancer cell stemness or drug resistance. Given integrin β 3's relationship with Wnt/β-catenin signaling, we determine whether HOXD3 regulates integrin β 3 activity through Wnt/β-catenin signaling. We found that, even though HOXD3 increased the expression of Wnt/β-catenin downstream genes, it did not restore Wnt/β-catenin signaling activity, which was inhibited in integrin β3 knockdown breast cancer cells. CONCLUSION We demonstrate that HOXD3 plays a critical role in breast cancer stemness and drug resistance via integrin β3-mediated Wnt/β-catenin signaling. Our findings open the possibility for improving the current standard of care for breast cancer patients by designing targeted molecular therapies that overcome the barriers of cancer cell stemness and drug resistance.

Abstract
Endometrial cancer is the most common, and second most lethal, gynecological malignancy, and its rates of incidence and death are growing. This is likely attributable to increased numbers of high-risk type II endometrial cancers which account for ~30% of cases but ~75% of deaths due to their aggressive and metastatic behaviour. Histopathological and in vitro functional studies suggest that aberrant TGFβ1 signaling may contribute to endometrial cancer development and the acquisition of invasive/metastatic characteristics. However, little is known about the cellular and molecular mechanisms of TGFβ1 in high-risk endometrial cancers. In the present study, we examined the roles and mechanisms of TGFβ1 on cell adhesion and motility in type II endometrial cancer cell lines, KLE and HEC-1B. We show that treatment with TGFβ1 increases cell adhesion to vitronectin and transwell cell migration. We also demonstrate that TGFβ1 treatment increases integrin β3 and αv mRNA and protein levels via SMAD-independent MEK-ERK1/2 signaling. Importantly, siRNA depletion or antibody-mediated blocking of integrin αvβ3 reversed the effects of TGFβ1 on cell adhesion and migration. Our results suggest that TGFβ1-MEK-ERK1/2-integrin αvβ3 signaling could contribute to the invasive behaviour of high-risk endometrial cancer by promoting cell adhesion and migration.

Abstract
Japanese encephalitis virus (JEV) is a mosquito-borne flavivirus that is one of the major causes of viral encephalitis diseases worldwide. The JEV envelope protein facilitates viral entry, and its domain III contains an Arg-Gly-Asp (RGD) motif, that may modulate JEV entry through the RGD-binding integrin. In this study, the roles of integrin αv and β3 on the infection of JEV were evaluated. Reduced expression of integrin αv/β3 by special shRNA confers 2 to 4-fold inhibition of JEV replication in BHK-21 cells. Meanwhile, antibodies specific for integrin αv/β3 displayed ~58% and ~33% inhibition of JEV infectivity and RGD-specific peptides produced ~36% of inhibition. Expression of E protein and JEV RNA loads were clearly increased in CHO cells transfected with cDNA encoding human integrin β3. Moreover, integrin αv mediates JEV infection in viral binding stage of life cycle. Therefore, our study suggested that integrin αv and β3 serve as a host factor associated with JEV entry into the target cells.

Abstract
Background Clinical ovulation induction induces blood estrogen (E2) in excess of physiological levels, which can hinder uterine receptivity. In contrast, progesterone produces the opposite clinical effect, suggesting that it might be capable of recovering the lost receptivity resulting from exposure to high estrogen levels. Integrins are the most widely used biological markers for monitoring uterine conditions. We studied progesterone-induced changes in integrin β expression patterns as biomarkers for changes in uterine receptivity in response to increased estrogen levels. Methods Endometrial biopsy samples from patients were screened for their estrogen (E2) and progesterone (P4) content and expressing levels of integrin β1 and β3. Uterine receptivity was evaluated using human endometrial adenocarcinoma cells in an embryo attachment model. The respective and concatenated effects of embryo attachment and changes in the integrin β1 and β3 expression patterns on the adenocarcinoma cell plasma membranes in response to 100 nM concentrations of E2 and P4 were evaluated. Results Increased blood E2 concentrations were associated with significantly decreased the levels of integrin β3 expression in uterine biopsy samples. In vitro experiments revealed that a 100 nM E2 concentration inhibited the distribution of integrin β3 on the plasma membranes of human endometrial adenocarcinoma cells used in the embryo attachment model, and resulted in decreased rates of embryo attachment. In contrast, P4 enhanced the expression of integrin β1 and promoted its distribution on the plasma membranes. Furthermore, P4 recovered the embryo attachment efficiency that was lost by exposure to 100 nM E2. Conclusions Blood E2 and P4 levels and integrin β3 and β1 expression levels in uterine biopsy samples should be considered as biomarkers for evaluating uterine receptivity and determining the optimal time for embryo transfer.

Abstract
Background Integrin β3 is involved in tumor and endothelial cell biology as well as in platelet aggregation. Herein, we evaluated the predictive potential of three germline single nucleotide polymorphisms (SNPs) in the integrin β3 gene (rs3809865, rs5918 and rs4642) to predict the risk of venous thromboembolism (VTE) in colorectal cancer (CRC) patients, which is one of the leading causes of death among cancer patients. Methods 112 patients diagnosed with CRC enrolled in the prospective Vienna Cancer and Thrombosis Study (CATS) were assessed with a median follow-up of 46 months. DNA was isolated from venous blood samples and SNPs were analyzed by the PCR-RFLP method. Results VTE occurred in 12% (n = 13) of all patients. The SNPs rs5918 and rs4642 were not associated with VTE risk. For rs3809565, 23% (n = 11) of patients had the A/A genotype, 4% (n = 2) had the A/T genotype, but none (0%) had the T/T genotype. In the univariate analysis, patients with the A/A genotype had a significantly higher risk to develop VTE compared to the other polymorphisms (P = 0.0005 after Fine and Gray). In the multivariable analysis, the predictive value remained significant. Conclusions This study identified the rs3809865 A/A genotype as an independent risk factor for VTE in CRC patients. Our findings would help identify high risk patients and would be essential for tailored anticoagulant prophylaxis.

Abstract
OBJECTIVE Cancer is one of the most common risk factor of venous thromboembolism (VTE). Our previous studies have shown that integrin subunits β1, β2 and β3 were the core proteins of venous thrombi and potential useful biomarker of VTE. This study aimed to explore the expression status of core proteins (integrin subunits β1, β2 and β3) in cancer patients. METHODS This is a case-control study. A total of 144 inpatients (54 females) with clinically proven cancers were recruited into this study, meanwhile 200 inpatients without cancer matched in sex and age were recruited as control group. Flow cytometry was done to measure the expressions of blood integrin β1, β2, β3 and cellular immunity related variables (CD3, CD4, CD8, CD4/CD8, CD16CD56 and CD19). The association degree between increased core proteins and cancers was analyzed by calculating the relative risk (RR). RESULTS The expression of integrin β1 and β3 were markedly increased in patients with cancer (P=0.001 and 0.008). Integrin β2 was also mildly increased in patients with cancer (P=0.274). The relative risk ratio (RR) of increased integrin β1, β2 and β3 in cancer patients was 1.655 (95% CI: 1.321-2.074, P=0.000), 1.314 (95% CI: 1.052-1.642, P=0.021) and 1.852, (95% CI: 1.097-3.126, P=0.028), respectively. Combined analysis with integrin β1, β2 and β3 showed that the relative risk ratio (RR) of increased in cancer patients was 4.895 (95% CI: 1.645-14.563, P=0.002). CD3, CD4, CD4/CD8 and CD19 were significantly decreased (P=0.004, P=0.000, P=0.000, P=0.000, respectively) in patients with cancer, while CD8 and CD16CD56 were markedly increased in cancer patients (P=0.005, P=0.035). CONCLUSIONS As the core proteins of venous thrombi, integrin β1 and β3 were markedly increased expression in patients with cancer, which maybe explain the increased risk of VTE in cancer patients. A weakened or disordered immune system might be the basis of VTE in condition.

Abstract
BACKGROUND Recent studies have reported contrasting results regarding the association of polymorphisms in two integrin genes, ITGA2 and ITGB3, with ischemic stroke. AIMS The present study aimed to investigate the correlation between the ITGA2 C807T and ITGB3 T176C polymorphic loci with ischemic stroke, as well as plasma lipid and lipoprotein levels. STUDY DESIGN Case control study. METHODS Human venous blood samples were collected from patients admitted for ischemic stroke (n=350, 'patients') and healthy individuals (n=300, 'controls'). Blood was genotyped at these loci by polymerase chain reaction-restriction fragment length polymorphism. Plasma lipid and lipoprotein levels were measured by routine enzymatic, masking, and turbidimetry methods. RESULTS As expected, total cholesterol, triglycerides, and low-density lipoprotein were all significantly higher in patients than in controls (p<0.05). Genotype and allele frequencies of ITGA2 C807T were significantly different between patients and controls (p<0.05), but no difference was detected in genotype or allele frequencies for ITGA3 T176C. For ITGA-2, the T allele conferred a 1.226 times higher relative risk of ischemic stroke than the C allele (odds ratio=1.226, 95% confidence interval=1.053-1.428). Similarly, total cholesterol was higher in T allele carriers than in non-carriers (p<0.05). CONCLUSION ITGA2 C807T polymorphism is associated with ischemic stroke, with the T allele acting as a susceptibility allele that appears to confer increased cholesterol levels.
