Abstract
Leaf rust (LR) and stripe rust (YR) are important diseases of wheat worldwide. We used 148 recombinant inbred lines (RIL) from the cross of Avocet × Kundan for determining and mapping the genetic basis of adult plant resistance (APR) loci. The population was phenotyped LR and YR for three seasons in field trials conducted in Mexico and genotyped with the diversity arrays technology sequencing (DArT-Seq) and simple sequence repeat markers. The final genetic map was constructed using 2,937 polymorphic markers with an average distance of 1.29 centimorgans between markers. Inclusive composite interval mapping identified two co-located APR quantitative trait loci (QTL) for LR and YR, two LR QTL, and three YR QTL. The co-located resistance QTL on chromosome 1BL corresponded to the pleiotropic APR gene Lr46/Yr29. QLr.cim-2BL, QYr.cim-2AL, and QYr.cim-5AS could be identified as new resistance loci in this population. Lr46/Yr29 contributed 49.5 to 65.1 and 49.2 to 66.1% of LR and YR variations, respectively. The additive interaction between detected QTL showed that LR severities for RIL combining four QTL ranged between 5.3 and 25.8%, whereas the lowest YR severities were for RIL carrying QTL on chromosomes 1BL + 2AL + 6AL. The high-density DArT-Seq markers across chromosomes can be used in fine mapping of the targeted loci and development SNP markers.

Abstract
Purinergic signaling is involved in pain generation and modulation in the nociceptive sensory nervous system. Adenosine triphosphate (ATP) induces pain via activation of ionotropic P2X receptors while adenosine mediates analgesia via activation of metabotropic P1 receptors. These purinergic signaling are determined by ecto-nucleotidases that control ATP degradation and adenosine generation. Using enzymatic histochemistry, we detected ecto-AMPase activity in dental pulp, trigeminal ganglia (TG) neurons, and their nerve fibers. Using immunofluorescence staining, we confirmed the expression of ecto-5'-nucleotidase (CD73) in trigeminal nociceptive neurons and their axonal fibers, including the nociceptive nerve fibers projecting into the brainstem. In addition, we detected the existence of CD73 and ecto-AMPase activity in the nociceptive lamina of the trigeminal subnucleus caudalis (TSNC) in the brainstem. Furthermore, we demonstrated that incubation with specific anti-CD73 serum significantly reduced the ecto-AMPase activity in the nociceptive lamina in the brainstem. Our results indicate that CD73 might participate in nociceptive modulation by affecting extracellular adenosine generation in the trigeminal nociceptive pathway. Disruption of TG neuronal ecto-nucleotidase expression and axonal terminal localization under certain circumstances such as chronic inflammation, oxidant stress, local constriction, and injury in trigeminal nerves may contribute to the pathogenesis of orofacial neuropathic pain.

Abstract
With advances in natural orifice transluminal endoscopic surgery, peroral endoscopic myotomy (POEM) has become a novel treatment for esophageal achalasia. In this study, we investigated the feasibility and safety of POEM in patients with achalasia after failed endoscopic interventions. Data on all patients undergoing POEM treatment of achalasia were collected prospectively. We enrolled 61 patients who underwent POEM for achalasia between July 2011 and January 2014. The preoperative intervention group included patients who had undergone botulinum toxin injection or pneumatic balloon dilation before POEM. The preoperative, operative, and short-term outcome data between the groups were compared. Among preoperative intervention group, 22 patients received endoscopic therapy before being referred for operation (18 dilation only, 2 botulinum toxin only, and 2 both treatments). Procedure time in the preoperative intervention group was similar to the nonpreoperative intervention group (60.8 ± 30.9 vs. 62.0 ± 21.0 minutes, P = 0.863). Both groups demonstrated significant improvement in Eckardt scores and manometric outcomes at 1-year follow-up. There were no significant differences in pretreatment and posttreatment D-values of symptom scores and lower esophageal sphincter pressures between groups (6.2 ± 2.2 vs. 6.1 ± 1.8, P = 0.840; 27.9 ± 17.6 vs. 24.9 ± 15.2; P = 0.569). There was also no significant difference in the incidence of intraoperative complications (P = 0.958) and gastroesophageal reflux rate (23.5% vs. 20.0%, P = 0.771) between the two groups. Our study demonstrated that POEM is safe and effective, even for treating achalasia in the setting of failed endoscopic interventions.

Abstract
To evaluate associations by EGFR mutation status for lung adenocarcinoma risk among never-smoking Asian women, we conducted a meta-analysis of 11 loci previously identified in genome-wide association studies (GWAS). Genotyping in an additional 10,780 never-smoking cases and 10,938 never-smoking controls from Asia confirmed associations with eight known single nucleotide polymorphisms (SNPs). Two new signals were observed at genome-wide significance (P < 5 × 10-8), namely, rs7216064 (17q24.3, BPTF), for overall lung adenocarcinoma risk, and rs3817963 (6p21.3, BTNL2) which is specific to cases with EGFR mutations. In further sub-analyses by EGFR status, rs9387478 (ROS1/DCBLD1) and rs2179920 (HLA-DPB1) showed stronger estimated associations in EGFR-positive compared to EGFR-negative cases. Comparison of the overall associations with published results in Western populations revealed that the majority of these findings were distinct, underscoring the importance of distinct contributing factors for smoking and non-smoking lung cancer. Our results extend the catalogue of regions associated with lung adenocarcinoma in non-smoking Asian women and highlight the importance of how the germline could inform risk for specific tumour mutation patterns, which could have important translational implications.

Abstract
Mutations in bone morphogenetic protein 1 (BMP1) in humans or deletion of BMP1 and related protease tolloid like 1 (TLL1) in mice lead to osteogenesis imperfecta (OI). Here, we show progressive periodontal defects in mice in which both BMP1 and TLL1 have been conditionally ablated, including malformed periodontal ligament (PDL) (recently shown to play key roles in normal alveolar bone formation), significant loss in alveolar bone mass ( P < 0.01), and a sharp reduction in cellular cementum. Molecular mechanism studies revealed a dramatic increase in the uncleaved precursor of type I collagen (procollagen I) and a reduction in dentin matrix protein 1 (DMP1), which is partially responsible for defects in extracellular matrix (ECM) formation and mineralization. We also showed a marked increase in the expression of matrix metallopeptidase 13 (MMP13) and tartrate-resistant acid phosphatase (TRAP), leading to an acceleration in periodontal breakdown. Finally, we demonstrated that systemic application of antibiotics significantly improved the alveolar bone and PDL damage of the knockdown phenotype, which are thus shown to be partially secondary to pathogen-induced inflammation. Together, identification of the novel roles of BMP1 and TLL1 in maintaining homeostasis of periodontal formation, partly via biosynthetic processing of procollagen I and DMP1, provides novel insights into key contributions of the extracellular matrix environment to periodontal homeostasis and contributes toward understanding of the pathology of periodontitis.

Abstract
BACKGROUND Directly acting antiviral agents (DAA) have been associated with hepatic decompensation, especially in patients with pre-treatment cirrhosis, but this risk is not well defined. AIM To determine the incidence of hepatic decompensation, liver transplantation, death and worsening renal function in patients treated with a Paritaprevir/ritonavir, Ombitasvir, Dasabuvir (PrOD), sofosbuvir/simeprevir or sofosbuvir/ledipasvir regimen. METHODS We followed ERCHIVES participants treated with the above regimens for up to 12 weeks post-treatment. We excluded those with HIV, HBsAg+ and pre-existing diagnosis of hepatic decompensation and hepatocellular carcinoma. RESULTS Of 3728 persons on PrOD, 1578 on sofosbuvir/simeprevir and 10 440 on sofosbuvir/ledipasvir, incidence rates (95% CI) of hepatic decompensation/1000 patient-years were 10.6 (5.89-17.36) for the PrOD, 32.4 (20.74-48.16) for the sofosbuvir/simeprevir and 13.0 (9.74-17.10) for the sofosbuvir/ledipasvir. Among those with baseline cirrhosis, these rates were 36.9 (19.1-64.5), 61.8 (38.2-94.5) and 41.1 (29.9-55.2) respectively, while among those without cirrhosis at baseline, these rates were 2.7 (0.6-8.0), 7.5 (1.5-21.8) and 2.7 (1.2-5.4). Advanced fibrosis was associated with increased risk of hepatic decompensation in all groups [HR (95% CI) per 0.5 unit increase in FIB-4 score: PrOD 1.11 (1.07-1.16); sofosbuvir/simeprevir 1.03 (1.01-1.05); sofosbuvir/ledipasvir 1.02 (1.01-1.03)]. There were no deaths. Proportion of persons with eGFR decrease >30 ml/min/1.73 m2 was higher among the PrOD group, but presence of cirrhosis did not appear to affect this. CONCLUSIONS The incidence of hepatic decompensation in persons treated with PrOD, up to 12 weeks after completion of treatment, was comparable to those treated with sofosbuvir/ledipasvir regimen, and was lower than among those treated with a sofosbuvir/simeprevir regimen. Such risk was predominantly observed in those with pre-treatment cirrhosis.

Abstract
Objective: To explore the clinical features of lymphoplasmacytic diseases with MyD88 L265P mutation. Methods: To analyze the distribution of MYD88 L265P mutation in patients with lymphoplasmacytic diseases by using of ARMS PCR-CE. Results: There were 25(30.9%) MyD88 L265P mutated patients in 81 patients. The mutation was frequently observed in 14 patients with WM (77.8%, 14/18), 2 patients with lymphoplasmacytic lymphoma (66.7%, 2/3), 1 acute lymphocytic leukemia patient (50.0%, 1/2), 3 multiple myeloma patients (30.0%, 3/10), 1 patient with monoclonal gammopathy of undetermined significance (25%, 1/4), 3 patients with chronic lymphocytic leukemia (13.0%, 3/23) and 1 lymphoma patient (4.8%, 1/21). 20 (80%, 20/25) patients were identified with IgM subtype. Compared with wild-type group of 56 cases, mutated patients were older (median age: 67 years vs 55 years, P< 0.001), with lower WBC count (median count: 5.23 × 109/L vs 10.80 × 109/L, P=0.001), lower HGB level (median count: 85 g/L vs 119 g/L, P<0.001). Conclusion: MyD88 L265P mutation was mainly observed in patients with IgM subtype lymphoplasmacytic diseases, and Waldenstrom' s macroglobulinemia was the most common disease. Compared with the wild-type group, patients with MyD88 L265P mutation were older and had lower WBC count, lower level of HGB. However, further studies were needed to test the prognostic value of MyD88 L265P mutation.

Abstract
The transcriptional factor Forkhead box k1 (FOXK1) is a member of the FOX family. The abnormal expression of FOXK1 may have an important role in tumour development. Our previous studies showed that four-and-a-half LIM protein 2 (FHL2) is a critical inducer of the epithelial-to-mesenchymal transition (EMT) and invasion. However, the molecular mechanism by which FOXK1 synergizes with FHL2 tumour proliferation, EMT and metastasis is not well defined. We evaluated that messenger RNA (mRNA) and protein expression levels by quantitative RT–PCR, western blot, immunofluorescence and immunohistochemistry (IHC) assays. The migration and invasive abilities of colorectal cancer (CRC) cells were evaluated using short hairpin RNA (shRNA)-mediated inhibition in vitro and in vivo. We showed that FOXK1 expression was upregulated in CRC compared with matched normal tissues. FOXK1 physically interacts with FHL2 in CRC. Moreover, higher expression levels of the two proteins were significantly associated with differentiation, lymph node metastasis, AJCC stage and poorer prognosis. Furthermore, the overexpression of FOXK1 in CRC cells is associated with EMT, invasion and metastasis. However, the siRNA-mediated repression of FHL2 in FOXK1-overexpressing cells reversed EMT and both the proliferative and metastatic phenotypes in vitro and in vivo. These data identified that the co-expression of FOXK1 and FHL2 enhances cell proliferation and metastasis through the induction of EMT. Thus, FOXK1 and FHL2 may serve as putative targets in the combined therapy of CRC.

Abstract
Adipose-derived stem cells (ADSCs) show nearly unlimited potential in medical and animal science. Currently, understanding of the biological mechanisms regulating ADSC growth in vitro remains very limited. Histone acetylation, an epigenetic modification, plays a key role in maintaining stem cell properties. To further study its effect on ADSC growth characteristics in vitro, we treated goat ADSCs with the histone deacetylase inhibitors trichostatin A (TSA) and vorinostat (SAHA). This inhibited SIRT1 expression and increased histone H3K9 acetylation, leading to decreased cell viability, cell cycle arrest, and apoptosis. Quantitative real-time polymerase chain reaction revealed that H3K9 hyperacetylation stimulated transcription of NANOG, OCT4, SOX2, and TERT, but inhibited that of PCNA, P53, and BAX. Western blotting indicated that TSA and SAHA increased protein expression of NANOG, reduced that of SOX2, TERT, PCNA, P53, and BAX, and did not change that of OCT4. These findings provide new experimental evidence contributing to our understanding of the mechanisms underlying ADSC growth characteristics in vitro.

Abstract
The Far-infrared Tangential Interferometer/Polarimeter (FIReTIP) system has been refurbished and is being reinstalled on the National Spherical Torus Experiment-Upgrade (NSTX-U) to supply real-time line-integrated core electron density measurements for use in the NSTX-U plasma control system (PCS) to facilitate real-time density feedback control of the NSTX-U plasma. Inclusion of a visible light heterodyne interferometer in the FIReTIP system allows for real-time vibration compensation due to movement of an internally mounted retroreflector and the FIReTIP front-end optics. Real-time signal correction is achieved through use of a National Instruments CompactRIO field-programmable gate array.

Abstract
As meat quality is basically dependent on muscle fibre characteristics, it is important to know how muscle fibres are regulated and transformed. This study aimed to investigate the effect of maternal dietary supplementation on muscle fibre types using 3% saturated fatty acid (palmitic acid, PA) or 3% unsaturated fatty acid (linoleic acid, LA) from 80 days of gestation to the weaning of offspring (25 days post-natal). The results indicated that higher mRNA levels of MyHCI type genes were found in the soleus muscles of piglets that suckled from LA-supplemented sows than from PA-supplemented sows. In addition, LA treatment increased the gene expression of the type I muscle fibre marker troponin I (p < 0.01), suggesting that LA promoted muscle fibre type transformation to type I fibres. Moreover, PGC-1α (p < 0.01) and MEF2c (p < 0.05) mRNA levels were higher in the piglets from the LA treatment group than in those from the PA treatment group. Furthermore, LA supplementation also significantly increased AMP-activated protein kinase (AMPK) mRNA levels (p < 0.05), which is an upstream regulator of PGC-1α. Collectively, these findings demonstrated that maternal dietary LA supplementation promoted muscle fibre transformation to type I fibre and that this process may be mediated through an AMPK-dependent pathway.

Abstract
FAXDC2 (fatty acid hydroxylase domain containing 2) is a member of the fatty acid hydroxylase superfamily. Given the important role of fatty acids in megakaryocytes, we have studied the role of this gene in the development of this lineage. Here we show that the expression of FAXDC2 is constantly elevated during megakaryocyte maturation. In contrast, FAXDC2 is significantly downregulated in acute myeloid leukemia and acute megakaryoblastic leukemia. Moreover, FAXDC2 overexpression promotes the differentiation of megakaryocytic cell lines and primary cells, whereas its knockdown disrupts their maturation. Mechanism study shows that FAXDC2 overexpression enhances extracellular signal-regulated kinase (ERK) signaling and increases RUNX1 (Runt-related transcription factor 1) expression. FAXDC2 also restores megakaryocytic differentiation in cells exposed to an ERK inhibitor or those expressing a dominant negative form of RUNX1. Finally, FAXDC2 overexpression leads to an increase in sphingolipid GM3 synthase, suggesting a potential role of FAXDC2 in lipid metabolism that increases ERK signaling and facilitates megakaryocyte differentiation. Together, these results show that FAXDC2 plays a novel role in development of megakaryocytes and its dysregulation may contribute to abnormal hematopoietic cell development in leukemia.

Abstract
Background The associations between microRNAs and lung cancer have received increasing attention. This study assess the association between polymorphisms in miR-135a-2, miR-219-2 and miR-211 genes and the risk of lung cancer, as well as the gene–environment interaction between these polymorphisms and cooking oil fume exposure. Methods A case–control study featuring 268 cases and 266 controls was conducted. The associations of miR-135a-2 rs10459194, miR-219-2 rs10988341 and miR-211 rs1514035 polymorphisms with the risk of lung cancer were analyzed. The gene–environment interactions were also reported on both additive and multiplicative scales. Results There were no statistically significant associations between the single-nucleotide polymorphisms (SNPs) and lung cancer or lung adenocarcinoma. The individuals with both a risk genotype of miRNA SNPs and exposure to a risk factor (cooking oil fumes) were at higher risk of lung cancer than those with only one of these two risk factors (odd ratios of 2.208, 1.285 and 1.813 for miR-135a-2 rs10459194; 2.164, 1.209 and 1.806 for miR-219-2 rs10988341; and 2.122, 1.146 and 1.725 for miR-211 rs1514035, respectively). However, the measures of biological interaction indicate that there was no such interaction between the three SNPs and exposure to cooking oil fumes on an additive scale. Logistic regression models also suggested that the gene–environment interactions were not statistically significant on a multiplicative scale. Conclusions There were no significant associations between the polymorphisms in miRNAs (miR-26a-1 rs7372209, miR-605 rs2043556 and miR-16-1 rs1022960) and the risk of lung cancer in the Chinese nonsmoking female population. The interactions between these polymorphisms in miRNAs and cooking oil fume exposure were also not statistically significant.

Abstract
OBJECTIVE Notch signaling has been identified as a critical regulator in cartilage development and joint maintenance, and loss of Notch signaling in all joint tissues results in an early and progressive osteoarthritis (OA)-like pathology. This study investigated the targeted cell population within the knee joint in which Notch signaling is required for normal cartilage and joint integrity. METHODS Two loss-of-function mouse models were generated with tissue-specific knockout of the core Notch signaling component, RBPjκ. The AcanCre(ERT2) transgene specifically removed Rbpjκ floxed alleles in postnatal joint chondrocytes, while the Col1Cre(2.3kb) transgene deleted Rbpjκ in osteoblast populations, including subchondral osteoblasts. Mutant and control mice were analyzed via histology, immunohistochemistry (IHC), real-time quantitative polymerase chain reaction (qPCR), X-ray, and microCT imaging at multiple time-points. RESULTS Loss of Notch signaling in postnatal joint chondrocytes results in a progressive OA-like pathology, and triggered the recruitment of non-targeted fibrotic cells into the articular cartilage potentially due to mis-regulated chemokine expression from within the cartilage. Upon recruitment, these fibrotic cells produced degenerative enzymes that may lead to the observed cartilage degradation and contribute to a significant portion of the age-related OA-like pathology. On the contrary, loss of Notch signaling in subchondral osteoblasts did not affect normal cartilage development or joint maintenance. CONCLUSIONS RBPjκ-dependent Notch signaling in postnatal joint chondrocytes, but not subchondral osteoblasts, is required for articular cartilage and joint maintenance.

Abstract
Breast cancer is the worldwide leading cause of cancer mortality in women. The majority of deaths from breast cancer arise from metastasis of local tumors. Cancer cells support their rapid proliferation by diverting metabolites into anabolic pathways, but during cancer metastasis, the proliferative program of invasive cancer cells is suspended for a migratory phenotype. In this study, we demonstrated that both mature forms of miRNA-485, miR-485-3p and miR-485-5p were involved in regulating mitochondrial respiration, cell migration and cell invasion in breast cancer cells by directly targeting and inhibiting the expression of PGC-1α. Specifically, the expression levels of both miR-485-3p and miR-485-5p were decreased in breast cancer tissues. Overexpression of miR-485-3p and miR-485-5p suppressed mitochondrial respiration and potential for cell migration and invasion in vitro, and also inhibited spontaneous metastasis of breast cancer cells in vivo. The suppression of mitochondrial respiration and cell invasion could be partially relieved by restoration of PGC-1α expression.

Abstract
Genome-wide association studies (GWAS) of lung cancer in Asian never-smoking women have previously identified six susceptibility loci associated with lung cancer risk. To further discover new susceptibility loci, we imputed data from four GWAS of Asian non-smoking female lung cancer (6877 cases and 6277 controls) using the 1000 Genomes Project (Phase 1 Release 3) data as the reference and genotyped additional samples (5878 cases and 7046 controls) for possible replication. In our meta-analysis, three new loci achieved genome-wide significance, marked by single nucleotide polymorphism (SNP) rs7741164 at 6p21.1 (per-allele odds ratio (OR) = 1.17; P = 5.8 × 10(-13)), rs72658409 at 9p21.3 (per-allele OR = 0.77; P = 1.41 × 10(-10)) and rs11610143 at 12q13.13 (per-allele OR = 0.89; P = 4.96 × 10(-9)). These findings identified new genetic susceptibility alleles for lung cancer in never-smoking women in Asia and merit follow-up to understand their biological underpinnings.

Abstract
BACKGROUND MicroRNAs play important roles in the development of human chronic diseases including lung cancer. This is the first case-control study of lung cancer in a non-smoking female population in northeast China, to evaluate the roles of the polymorphisms in pre-miRNAs on risk of lung cancer. METHODS The genotypes of six polymorphisms in miRNAs were determined in 575 patients with lung cancer and 608 healthy controls who were frequency matched for age. RESULTS For miR-146a rs2910164, individuals carrying heterozygous CG or homozygous GG genotype had decreased risks of lung cancer compared with those carrying homozygous wild CC genotype (adjusted odds ratios were 0.76 and 0.64, 95% confidence intervals were 0.59-0.99 and 0.46-0.90, P values were 0.039 and 0.010, respectively). G allele of rs2910164 was associated with a lower risk of lung cancer with a significant odds ratio of 0.80. MiR-423 rs6505162CA or AA genotype was associated with significantly decreased risk for lung cancer compared to CC genotype (adjusted odds ratios were 0.77 and 0.54). The significant result was also found in the allele model with odds ratio of 0.75. However, miR-196a2 rs11614913, miR-30c-1 rs928508, miR-608 rs4919510 and miR-27a rs895819 polymorphisms were not significantly associated with lung cancer risks in any models. The similar results were also found in lung adenocarcinoma patients. CONCLUSIONS These findings suggest that miR-146a rs2910164C>G and miR-423 rs6505162C>A polymorphisms may contribute to genetic susceptibility to lung cancer and lung adenocarcinoma in Chinese non-smoking females.

Abstract
Chemotherapy paclitaxel yields significant reductions in tumor burden in the majority of advanced non-small cell lung cancer (NSCLC) patients. However, acquired resistance limits its clinical use. Here we demonstrated that the histone deacetylase (HDAC) was activated in paclitaxel-resistant NSCLC cells, and its activation promoted proliferation and tumorigenesis of paclitaxel-resistant NSCLC cells in vitro and in vivo. By contrast, knockdown of HDAC1, a primary isoform of HDAC, sensitized resistant cells to paclitaxel in vitro. Furthermore, we observed that overexpression of HDAC1 was associated with the downregulation of p21, a known HDAC target, in advanced NSCLC patients with paclitaxel treatment, and predicted chemotherapy resistance and bad outcome. In addition, we also identified a novel HDACs inhibitor, SNOH-3, which inhibited HDAC expression and activity, induced cell apoptosis, and suppressed cell migration, invasion and angiogenesis. Notably, co-treatment with SNOH-3 and paclitaxel overcome paclitaxel resistance through inhibiting HDAC activity, leading to the induction of apoptosis and suppression of angiogenesis in vitro and in preclinical model. In summary, our data demonstrate a role of HDAC in paclitaxel-resistant NSCLC and provide a promising therapeutic strategy to overcome paclitaxel-acquired resistance.

Abstract
BACKGROUND MicroRNAs (miRNAs) are suggested to be very important in the development of lung cancer. This study assesses the association between polymorphisms in miRNA-related (miR)-26a-1, miR-605, and miR-16-1 genes and risk of lung cancer, as well as the effect of gene-environment interaction between miRNA polymorphisms and cooking fume exposure on lung cancer. METHODS A case-control study including 268 diagnosed nonsmoking female lung cancer patients and 266 nonsmoking female controls was carried out. Three miRNA polymorphisms (miR-26a-1 rs7372209, miR-605 rs2043556, and miR-16-1 rs1022960) were analyzed. Both additive and multiplicative interactions were assessed. RESULTS MiR-16-1 rs1022960 may be associated with the risk of lung cancer. Carriers with TT genotype of miR-16-1 rs1022960 were observed to have a decreased risk of lung cancer compared with CC and CT genotype carriers (odds ratio =0.550, 95% confidence interval =0.308-0.983, P=0.044). MiR-26a-1 rs7372209 and miR-605 rs2043556 showed no statistically significant associations with lung cancer risk. There were no significant associations between the three single nucleotide polymorphisms and lung adenocarcinoma. People with exposure to both risk genotypes of miR-26a-1 rs7372209 and cooking oil fumes were more likely to develop lung cancer than those with only genetic risk factor or cooking oil fumes (odds ratios were 2.136, 1.255, and 1.730, respectively). The measures of biological interaction and logistic models indicate that gene-environment interactions were not statistically significant on additive scale or multiplicative scale. CONCLUSION MiR-16-1 rs1022960 may be associated with the risk of lung cancer in a Chinese nonsmoking female population. The interactions between miRNA polymorphisms (miR-26a-1 rs7372209, miR-605 rs2043556, and miR-16-1 rs1022960) and cooking oil fumes were not statistically significant.
