Abstract
Lysine-specific demethylase 1 (LSD1 or KDM1A ) has emerged as a critical mediator of tumor progression in metastatic castration-resistant prostate cancer (mCRPC). Among mCRPC subtypes, neuroendocrine prostate cancer (NEPC) is an exceptionally aggressive variant driven by lineage plasticity, an adaptive resistance mechanism to androgen receptor axis-targeted therapies. Our study shows that LSD1 expression is elevated in NEPC and associated with unfavorable clinical outcomes. Using genetic approaches, we validated the on-target effects of LSD1 inhibition across various models. We investigated the therapeutic potential of bomedemstat, an orally bioavailable, irreversible LSD1 inhibitor with low nanomolar potency. Our findings demonstrate potent antitumor activity against CRPC models, including tumor regressions in NEPC patient-derived xenografts. Mechanistically, our study uncovers that LSD1 inhibition suppresses the neuronal transcriptional program by downregulating ASCL1 through disrupting LSD1:INSM1 interactions and de-repressing YAP1 silencing. Our data support the clinical development of LSD1 inhibitors for treating CRPC - especially the aggressive NE phenotype. Statement of Significance Neuroendocrine prostate cancer presents a clinical challenge due to the lack of effective treatments. Our research demonstrates that bomedemstat, a potent and selective LSD1 inhibitor, effectively combats neuroendocrine prostate cancer by downregulating the ASCL1- dependent NE transcriptional program and re-expressing YAP1.

Abstract
PURPOSE/OBJECTIVE(S) Several prospective trials in oligometastatic castration sensitive prostate cancer (omCSPC) have shown metastasis-directed therapy (MDT) can delay time to progression and initiation of androgen deprivation therapy (ADT) compared to observation. However, the optimal integration of ADT with MDT remains unclear. Here we report a multi-national, multi-institutional retrospective cohort of omCSPC treated with MDT to characterize the long-term outcomes of patients treated with MDT alone or in combination with ADT. MATERIALS/METHODS Patients with a controlled primary site and omCSPC (defined as ≤ 5 lesions on conventional imaging) treated with MDT with or without concurrent ADT and with at least 36 months follow-up were retrospectively screened across 13 institutions. The primary endpoints included biochemical progression free survival (bPFS) and radiographic progression free survival (rPFS) calculated using Kaplan-Meier method and stratified by treatment group (MDT alone vs MDT + ADT). Multivariable Cox regression was performed adjusted for variables found to be prognostic on univariate analysis. RESULTS Among 414 patients screened, a total of 263 patients treated between 2003 and 2018 met inclusion criteria and included. Of these, 105 received MDT alone and 158 received MDT+ADT, with median follow-up of 49.5 and 54.5 months, respectively. The majority were metachronous (90%) and had bone lesions (60%). Median ADT duration was 21.3 months (IQR 12.0- 31.9). Patients who received ADT vs. no ADT had poorer prognostic features including 23% vs. 1% synchronous (p<0.001), and 55% vs 40% Gleason 8-10 (p = 0.012). ADT use was associated with a better 5-year bPFS 24% vs 11% (p<0.0001) and rPFS 41% vs 29% (p<0.001). On multivariable Cox regression adjusting for post-MDT PSA nadir and salvage therapy, ADT use maintained significance for both bPFS (HR 0.51 (0.36, 0.71), p<0.001) and rPFS (HR 0.67, 95% CI 0.46-0.96, p = 0.03). CONCLUSION Long-term outcomes with MDT alone suggest a small proportion of patients experience sustained disease control. The addition of ADT appears to improve rPFS, however prospective studies are needed in order to allow for personalization of care in patients with omCSPC.

Abstract
Objective: To analyze the distribution characteristics of plasma renin concentration (PRC) in patients with aldosterone-producing adenoma (APA) and its impact on diagnosis. Methods: In this retrospective case series, clinical data from 200 patients with APA (80 men and 120 women; mean age 45.6 years) in the First Affiliated Hospital of Chongqing Medical University from November 2013 to January 2022 were evaluated. PRC was determined by automated chemiluminescence immunoassay. The distribution characteristics of PRC were analyzed, and 8.2 mU/L was used as the low renin cutoff to evaluate whether renin was suppressed. Results: The median PRC was 1.6 mU/L (range, 0.4-41.5 mU/L). There were 116 patients with APA with PRC of ≤2 mU/L, 41 patients with 2<PRC≤4 mU/L. PRC was not suppressed (PRC>8.2 mU/L) in 8.0% (16/200) of the patients with APA. And PRC was not suppressed in 2.5% (5/200) of the patients with APA, resulting in a primary aldosteronism negative screening outcome. Conclusions: Although most patients with APA have low PRC, there are a small number (8%) of patients whose PRC has not been fully suppressed, which can lead to missed diagnoses during primary aldosteronism screening. While primary aldosteronism is highly suspected, further investigations are required to determine the diagnosis, even if PRC is not fully suppressed at screening.

Abstract
Wnt-β-catenin signaling plays a key role in orthodontic tooth movement (OTM), a common clinical practice for malocclusion correction. However, its targeted periodontal ligament (PDL) progenitor cells remain largely unclear. In this study, we first showed a synchronized increase in Wnt-β-catenin levels and Axin2+ PDL progenitor cell numbers during OTM using immunostaining of β-catenin in wild-type mice and X-gal staining in the Axin2-LacZ knock-in line. Next, we demonstrated time-dependent increases in Axin2+ PDL progenitors and their progeny cell numbers within PDL and alveolar bones during OTM using a one-time tamoxifen-induced Axin2 tracing line (Axin2CreERT2/+; R26RtdTomato/+). Coimmunostaining images displayed both early and late bone markers (such as RUNX2 and DMP1) in the Axin2Lin PDL cells. Conversely, ablation of Axin2+ PDL cells via one-time tamoxifen-induced diphtheria toxin subunit A (DTA) led to a drastic decrease in osteogenic activity (as reflected by alkaline phosphatase) in PDL and alveolar bone. There was also a decrease in new bone mass and a significant reduction in the mineral apposition rate on both the control side (to a moderate degree) and the OTM side (to a severe degree). Thus, we conclude that the Axin2+ PDL cells (the Wnt-targeted key cells) are highly sensitive to orthodontic tension force and play a critical role in OTM-induced PDL expansion and alveolar bone formation. Future drug development targeting the Axin2+ PDL progenitor cells may accelerate alveolar bone formation during orthodontic treatment.

Abstract
Objective: To investigate the factors related to myasthenic crisis (MC) in myasthenia gravis patients (MG) with oropharyngeal involvement during hospitalization. Methods: The clinical data of 99 MG patients with oropharyngeal involvement who were admitted to Beijing Tongren Hospital from 2018 to 2020 were retrospectively reviewed. There were 52 males and 47 females, aged 17-89 (55±15) years old, with a disease duration of 1-240 [10 (4, 36)] months. Multivariable logistic regression analysis was used to determine the factors associated with MC. Results: A total of 19 (19.19%) patients developed into MC during hospitalization. Multivariate logistic regression analysis showed that age of hospitalization ≥ 60 years old (OR=31.378, 95%CI: 3.868-254.557, P=0.001), type B and C thymoma (OR=29.175, 95%CI: 2.986-285.016, P=0.004), excess oropharyngeal secretions (OR=12.649, 95%CI: 2.057-77.783, P=0.006) and infections (OR=9.539, 95%CI: 1.345-67.645, P=0.024) were independently related to MC in MG patients with oropharyngeal involvement. Conclusions: Older age, malignant thymoma, excess oropharyngeal secretions and infection are independently related to MC in MG patients with oropharyngeal involvement during hospitalization. Therefore, great attention should be paid to this type of MG patients, and increased oropharyngeal secretions and various infections should be actively treated, so as to reduce the occurrence of MC.

Abstract
OBJECTIVE To explore whether plasmacytoma variant translocation 1 (PVT1) could regulate glioblastoma multiforme (GBM) progression via microRNA-1301-3p (miR-1301-3p) and transmembrane BAX inhibitor motif containing 6 (TMBIM6) axis. MATERIALS AND METHODS Expression patterns of PVT1 and RMBIM6 in GBM patients were analyzed using GEPIA, an online gene expression analysis tool. Levels of PVT1 in GBM cells and normal cells were analyzed with quantitative real-time PCR method. Cell Counting Kit-8 (CCK-8), transwell invasion assay, and flow cytometry assay were applied to detect cell viability and apoptosis. Connections of PVT1 or TMBIM6 with miR-1301-3p were validated with bioinformatic tool and luciferase activity reporter assay. RESULTS PVT1 was significantly expressed in GBM tissues and cells. PVT1 promotes GBM cell proliferation and invasion but inhibits apoptosis in vitro. TMBIM6 was significantly expressed in GBM tissues. The knockdown of TMBIM6 reversed the stimulation effects of PVT1 on GBM cell malignancy behaviors with miR-1301-3p as a bridge. CONCLUSIONS Collectively, we showed PVT1 elevated TMBIM6 expression mediated by miR-1301-3p and thus to promote GBM progression.

Abstract
Children are susceptible to allergic rhinitis (caused by external allergens) accompanied by functional gastrointestinal disease, which seriously affects physical and mental health. Antihistamines and nasal spray hormones are commonly used in clinical treatment, but these drugs often have unsatisfactory efficacy and result in high recurrence rates. Therefore, understanding the pathogenesis of allergic rhinitis with functional gastrointestinal disease and seeking safer treatment and prevention methods is essential. Herein, molecular ecology and immunoassays were used to analyze correlations between pediatric allergic rhinitis with functional gastrointestinal disease and both the intestinal microbiota and gastrointestinal peptide levels. Fifty healthy children (healthy group) and 80 children with allergic rhinitis with functional gastrointestinal disease (case group: evenly divided into a control group (conventional drug therapy) and an intervention group (conventional drug therapy + glutamine+probiotics)), were enrolled. Bifidobacterium and Lactobacillus counts and the gastrin and motilin levels were lower in the case group than in the healthy group, whereas Enterobacter, yeast, and Enterococcus counts and the somatostatin, serotonin, and vasoactive intestinal peptide levels were higher. Post treatment, intestinal microbiota indices, gastrointestinal peptide levels, and intestinal barrier function were better in the intervention group than in the control group (p < 0.05). The intervention group had a significantly higher total therapeutic response rate (95.00%) than the control group (77.50%). The intestinal microbiota was closely associated with gastrointestinal peptide levels. Treatment with glutamine and probiotics regulated these levels, re-established balance in the intestinal microbiota, and restored intestinal barrier function.

Abstract
High brightness, high charge electron beams are critical for a number of advanced accelerator applications. The initial emittance of the electron beam, which is determined by the mean transverse energy (MTE) and laser spot size, is one of the most important parameters determining the beam quality. The bialkali photocathodes illuminated by a visible laser have the advantages of high quantum efficiency (QE) and low MTE. Furthermore, Superconducting Radio Frequency (SRF) guns can operate in the continuous wave (CW) mode at high accelerating gradients, e.g. with significant reduction of the laser spot size at the photocathode. Combining the bialkali photocathode with the SRF gun enables generation of high charge, high brightness, and possibly high average current electron beams. However, integrating the high QE semiconductor photocathode into the SRF guns has been challenging. In this article, we report on the development of bialkali photocathodes for successful operation in the SRF gun with months-long lifetime while delivering CW beams with nano-coulomb charge per bunch. This achievement opens a new era for high charge, high brightness CW electron beams.

Abstract
Continuous-wave photoinjectors operating at high accelerating gradients promise to revolutionize many areas of science and applications. They can establish the basis for a new generation of monochromatic x-ray free electron lasers, high-brightness hadron beams, or a new generation of microchip production. In this Letter we report on the record-performing superconducting rf electron gun with CsK_{2}Sb photocathode. The gun is generating high charge electron bunches (up to 10 nC/bunch) and low transverse emittances, while operating for months with a single photocathode. This achievement opens a new era in generating high-power beams with a very high average brightness.

Abstract
Objective: To investigate the clinical characteristics, treatment and prognosis of optic neuropathy associated with varicella zoster virus (VZV). Methods: Five cases of optic neuropathy associated with VZV infection from Department of Neurology between January 1, 2014 and March 31, 2019 were retrospectively collected. The clinical manifestations, treatment and prognosis were analyzed. Results: There were 7 eyes involved in 5 cases, 3 cases (3/5) involved only one eye, and 2 cases (2/5) involved both optic nerves. During the follow-up time, no recurrence was found. Severe visual impairment occurred in 4 eyes (4/7) and non-severe visual impairment in 3 eyes (3/7). Visual acuity improved significantly in 1 eye (1/7), turned better in 2 eyes (2/7), and remained unchanged in 4 eyes (4/7). In acute phase, abnormal signals of optic nerve and/or sheath were observed on MR images. Case 3 received antiviral and hormone therapy on the second day after the onset of the disease, and the visual acuity recovered well; the other 4 cases had poor prognosis. Conclusions: Head and face VZV infection can cause serious optic neuropathy, leading to severe visual dysfunction, and poor prognosis, but recurrence is rare. Early intravenous administration of antiviral drugs (acyclovir is the best) and hormones are recommended for VZV infection in this area. It is best to use drugs within 72 hours in order to avoid and reduce secondary optic neuropathy as far as possible.

Abstract
Cooling of beams of gold ions using electron bunches accelerated with radio-frequency systems was recently experimentally demonstrated in the Relativistic Heavy Ion Collider at Brookhaven National Laboratory. Such an approach is new and opens the possibility of using this technique at higher energies than possible with electrostatic acceleration of electron beams. The challenges of this approach include generation of electron beams suitable for cooling, delivery of electron bunches of the required quality to the cooling sections without degradation of beam angular divergence and energy spread, achieving the required small angles between electron and ion trajectories in the cooling sections, precise velocity matching between the two beams, high-current operation of the electron accelerator, as well as several physics effects related to bunched-beam cooling. Here we report on the first demonstration of cooling hadron beams using this new approach.

Abstract
Objective: To investigate the clinical features, imaging findings and prognosis of idiopathic intracranial hypertension (IIH) patients complicated with iron deficiency anemia (IDA). Methods: A total of 307 cases of IIH patients hospitalized in Beijing Tongren Hospital were retrospectively screened between January 1, 2011 and February 28, 2018. There were 49 anemia cases (15.96%) and 45 IDA cases (14.66%), respectively. Finally, 36 IDA patients were enrolled. The clinical characteristics, imaging findings, treatment and prognosis of these patients were analyzed. Results: IIH combined with IDA was more common in women of childbearing age (34/36). There were 30 obese and overweight cases (83.33%), with multiple subacute or chronic course of disease. The visual symptoms in the early IIH patients were first diagnosed in the Department of Ophthalmology. The first symptom was headache with/without visual symptoms (27 cases (75%)). Head MRI detected empty sella or partial empty sella, and 2 cases of venous sinus thrombosis were found in DSA examination. Of the 34 female patients, 24 had simple menometrorrhagia or menstrual disorder. All patients were given methyl acetate to reduce the intracranial pressure and iron therapy. Five patients received low molecular weight heparin-warfarin sequential treatment, 5 cases underwent gynecologic surgery and 2 male cases received hemorrhoid operation. There were 7 cases underwent lumbar cisterna-peritoneal shunt for visual impairment. During the follow-up, intracranial pressure decreased and visual function of patients improved significantly. Conclusions: IIH is frequently found in obese or overweight women at childbearing age and IDA may be an important cause of IIH. IIH can cause serious irreversible visual impairment. Therefore, early identification and active treatment should be performed. Correction of anemia can significantly improve the clinical symptoms of IIH. Operation should be employed for IIH patients with poor visual function or rapid progress, in order to reduce intracranial pressure and improve prognosis as soon as possible.

Abstract
OBJECTIVE To investigate the expression of long non-coding RNA CASC15 in gastric cancer tissue and its effect on the proliferation of gastric cancer cell line MKN28. MATERIALS AND METHODS We found that expression of lncRNA CASC15 in gastric cancer tissue was higher than normal gastric epithelium through the TCGA and Gene Expression Omnibus (GEO) database. Then, we detect the RNA level of CASC15 from clinical samples of 42 normal gastric epithelial tissues and 60 gastric cancer tissues. In order to explore the function of CASC15 in gastric cancer, we perform gain-function and loss-function assay in gastric cancer cell lines. RESULTS We found that expression of lncRNA CASC15 in gastric cancer tissue was higher than normal gastric epithelium through the TCGA database and the related microarray data set was searched from Gene Expression Omnibus (GEO) database. Then, we extracted total RNA from clinical samples of 42 normal gastric epithelial tissues and 60 gastric cancer tissues. The results of quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR) were consistent with those of TCGA analysis. Clinical data analysis showed that the expression of LncRNA CASC15 was correlated with the total survival, tumor size and TMN staging in clinical patients. Clinical data analysis showed that the expression level of CASC15 was correlated with tumor size and TNM stage in clinical patients. Compared with the negative control group, the proliferation and cell cloning ability of MKN28 cells overexpressing LncRNA CASC15 significantly increased (p<0.001), indicating that overexpression of LncRNA CASC15 promoted the proliferation of MKN28 cells. CONCLUSIONS The expression of LncRNA CASC15 was significantly higher in gastric cancer tissues and its expression was negatively correlated with the overall survival of clinical patients. It was positively correlated with the tumor size and TMN stage. LncRNA CASC15 could promote the proliferation of gastric cancer cells and was expected to become the molecular marker for prediction and prognosis of gastric cancer, as well as a potential therapeutic target.

Abstract
OBJECTIVE To investigate the association of aspirin resistance (AR) with mortality in a cohort of Chinese patients with acute ischemic stroke (AIS). METHODS One hundred and ninety-six ischemic stroke patients who received at least 7 days of aspirin therapy prior to stroke onset were enrolled. The outcome measure was all-cause and cardiovascular disease (CVD) mortality at 1-year follow-up. The relation of AR with the two end points was investigated with the use of logistic regression models. RESULTS The median age of included patients was 65(IQR, 56-76) years and 82(41.8%) were female. Thirty-five patients were defined as AR; thus, the rate was 17.9% (95%CI, 12.5% to 23.2%). The median NIHSS score was significantly higher in patients with AR than those with AS [12 (IQR, 10-17) vs. 7 (IQR, 4-10); Z=5.188; P<0.001]. Similarly, the median infarct volume was also significantly higher in AR than in AS [18.8 (IQR, 4.3-25.2) ml vs. 13.2 (IQR, 3.3-18.7) ml; Z=3.322; P=0.008]. During follow-up there were 43 patients (21.9%) died, including 24 CVD mortality (12.2%). In univariate logistic regression analysis, we found that the rate of all-cause mortality and CVD mortality increased by 390% (OR=4.90; 95%CI:2.24-10.75) and 422% (OR=5.22; 95%CI, 2.10-12.98) in AR group. After adjusting for all other significant predictors, AR still associated with high mortality and the rate of all-cause mortality and CVD mortality increased by 215% (OR=3.15; 95%CI:1.88-4.93) and 231% (OR=3.31; 95%CI, 1.96-522), respectively. CONCLUSIONS The present study shows that AR was a useful prognostic marker of all-cause or CVD mortality in Chinese patients with AIS.

Abstract
Objective:To evaluate the changes in the central auditory system of presbycusis by applying auditury brainstem response (ABR) and diffusion tensor imaging (DTI). Method:A total of twenty-five elderly subjects with expressed presbycusis, eight elderly subjects with normal hearing and fifteen healthy volunteers as young controls were enrolled in the study. Each participant was examined using ABR and DTI. ABR measures were obtained from all the subjects. The fractional anisotropy (FA) was measured at two brain regions of the auditory pathway-the inferior colliculus (IC) and Heschl's gyrus. Result:Higher FA values were recorded at the left side of the Heschl's gyrus in all three groups (P<0.05). There were no significant differences between the left and right side of the ABR results and FA values of inferior colliculus in the three groups (P>0.05). Aging increased ABR peak latencies, yet did not change the Ⅰ-Ⅴ interpeak latency interval. Comparing with the elderly subjects with normal hearing group, the wave Ⅴ latencies of the presbycusis group were prolonged (P<0.05). Comparing with the healthy control group, the FA values of the IC were reduced in both of the elderly subjects with normal hearing group and the presbycusis group (P<0.05). No statistically differences were observed between the presbycusis group and the elderly subjects with normal hearing group in the FA values of the IC (P>0.05). Significant differences between all groups were found in the FA values of the Heschl's gyrus, with higher values in the elderly subjects with normal hearing group than in the presbycusis group and even higher values in the healthy control group than in the elderly subjects with normal hearing group (P<0.05). Conclusion:The results indicated that the age-related microstructural changes exist in the central part of the auditory system, which are more obvious in the patients with presbycusis.

Abstract
While amyloid-beta (Aβ) peptides play a central role in the development of Alzheimer's disease (AD), recent evidence also implicates altered metabolism of L-arginine in the pathogenesis of AD. The present study systematically investigated how behavioural function and the brain and plasma arginine metabolic profiles changed in a chronic Aβ accumulation model using male APPswe/PS1ΔE9 transgenic (Tg) mice at 7 and 13 months of age. As compared to their wild-type (WT) littermates, Tg mice displayed age-related deficits in spatial water maze tasks and alterations in brain arginine metabolism. Interestingly, the plasma arginine metabolic profile was markedly altered in 7-month Tg mice prior to major behavioural impairment. Receiver operating characteristic curve analysis revealed that plasma putrescine and spermine significantly differentiated between Tg and WT mice. These results demonstrate the parallel development of altered brain arginine metabolism and behavioural deficits in Tg mice. The altered plasma arginine metabolic profile that preceded the behavioural and brain profile changes suggests that there may be merit in an arginine-centric set of ante-mortem biomarkers for AD.

Abstract
The mineralization-front theory is historically rooted in mineralization research fields for many decades. This theory is widely used to describe mineralization events in both osteogenesis and dentinogenesis. However, this model does not provide enough evidence to explain how minerals are propagated from the pulp-end dentin to dentin-enamel junction (DEJ). To address this issue, we modified the current research approaches by a) extending the mineral deposition windows of time from minutes to hours, instead of limiting the mineralization assay on days and weeks only; b) switching a regular fluorescent microscope to a more powerful confocal microscope; in which both mineral deposition rates and detail mineral labeling along with dentin tubules can be documented; and c) using reporter mice, including the Gli1-CreERT2 activated tomato and the 2.3 Col1-GFP to mark odontoblast processes combined with mineral dye injections. Our key findings are: 1) Odontoblast-processes, full of numerous mini-branches, evenly spread to entire dentin matrices with a high density of processes and a large diameter of the main process at the predentin-dentin junction; and 2) The minerals deposit along with entire odontoblast-processes and form many individual mineral collars surrounding odontoblast processes. As a result, these merged collars give rise to a single labeled line at the dentin-predentin junction, in which the dental tubules are wider in diameter and denser in odontoblast processes compared to other dentin areas. We therefore propose that it is the odontoblast-process that directly contributes to mineralization, which is not simply limited in the mineralization front at the edge of dentin and predentin, but occurs along with the entire odontoblast process. These new findings will shed new light on our understanding of dentin structure and function, as well as the mechanisms of mineralization.

Abstract
Objective: To evaluate the changes of macrophages and expression of Rac1 in the inflammatory site of Crohn's disease, and to investigate the effects of 6-thioguanine (6-TG) and peptidoglycan on apoptosis of human peripheral blood monocyte-macrophage by regulating Rac1 signaling pathway. Methods: Ten patients with Crohn's disease and eight healthy controls diagnosed were enrolled at Department of Gastroenterology and Hepatology, Tianjin Medical University General Hospital from January 2013 to January 2014. The number of macrophages, apoptosis and expression of Rac1 in the inflammation sites and non-inflammation sites of intestinal mucosa were detected in both patients and controls. Peripheral blood mononuclear cells (PBMCs) were sorted by CD14 immunomagnetic beads. The apoptosis of monocytes, expression of Rac1 and related apoptosis signaling molecules were detected in patients treated with peptidoglycan, 6-TG and Rac1 inhibitor NSC23766 and another 15 healthy donors. Results: The number of macrophages and apoptotic cells significantly increased in the inflammatory group of Crohn's disease patients compared with the non-inflammatory group. The expression of PAK1, downstream molecular of Rac1 signaling pathway of macrophages was also significantly higher in the inflammatory group of Crohn's disease patients than that in healthy controls and non-inflammatory group. Compared with control group, anti-apoptotic signals (NF-κB, Bcl-xL and STAT-3) in PBMCs increased in the peptidoglycan group, while slightly decreased in 6-TG group. 6-TG and NSC23766 significantly promoted peptidoglycan-related anti-apoptosis [peptidoglycan group (8.6±3.7)%, peptidoglycan+ 6-TG group (42.0±2.7)%, peptidoglycan+ NSC23766 group (58.5±6.9)%, P<0.05]. Conclusions: Peptidoglycan plays a role in the pathogenesis of Crohn's disease by recruiting macrophages. However, 6-TG inhibits peptidoglycan-induced activation of Rac1 signaling pathway leading to macrophage apoptosis.

Abstract
The long non-coding RNA, plasmacytoma variant translocation 1 (PVT1), is highly expressed in a variety of tumors, and is believed to be a potential oncogene. However, the role and mechanism of action of PVT1 in the carcinogenesis and progression of nasopharyngeal carcinomas (NPCs) remains unclear. In this study, for the first time, we have discovered that PVT1 shows higher expression in NPCs than in normal nasopharyngeal epithelial tissue, and patients with NPCs who show higher expression of PVT1 have worse progression-free and overall survivals. Additionally, we observed that the proliferation of NPC cells decreased, and their rate of apoptosis increased; these results indicated that the knockdown of PVT1 expression in the NPC cells induced radiosensitivity. Further, we have shown that the knockdown of PVT1 expression can induce apoptosis in the NPC cells by influencing the DNA damage repair pathway after radiotherapy. In general, our study shows that PVT1 may be a novel biomarker for prognosis and a new target for the treatment of NPCs. Additionally, targeting PVT1 may be a potential strategy for the clinical management of NPC and for the improvement of the curative effect of radiation in NPCs.

Abstract
Androgen receptor (AR) activation is critical for prostate cancer development and progression, including castration-resistance. The nuclear export signal of AR (NESAR) plays an important role in AR intracellular trafficking and proteasome-dependent degradation. Here, we identified the RNA helicase DHX15 as a novel AR co-activator using a yeast mutagenesis screen and revealed that DHX15 regulates AR activity by modulating E3 ligase Siah2-mediated AR ubiquitination independent of its ATPase activity. DHX15 and Siah2 form a complex with AR, through NESAR. DHX15 stabilized Siah2 and enhanced its E3 ubiquitin ligase activity, resulting in AR activation. Importantly, DHX15 was upregulated in prostate cancer specimens and its expression was correlated with Gleason scores and PSA recurrence. Furthermore, DHX15 immunostaining correlated with Siah2. Finally, DHX15 knockdown inhibited the growth of C4-2 prostate tumor xenografts in mice. Collectively, our data argue that DHX15 enhances AR transcriptional activity and contributes to prostate cancer progression through Siah2.

Abstract
PURPOSE To demonstrate the benefit and safety of conservative therapy for round ligament varicosities (RLVs) that are easily misdiagnosed as inguinal hernias. METHODS We retrospectively analyzed clinical materials of 41 consecutive cases of RLVs diagnosed by ultrasound in a single hospital from January 2011 to December 2015. Misdiagnosis rate, clinical and sonographic features, management after diagnosis and prognosis were recorded. RESULTS All forty-one cases were pregnant females in their second or third trimester. Twenty-eight cases were first misdiagnosed as inguinal hernias (68.3%). Thirty cases presented as reducible swelling in the inguinal area (73.2%), and twenty-five of which were painful (61.0%). Four cases only felt pain in the inguinal area without swelling (9.7%). Seven cases had no obvious discomfort (17.1%). All cases were diagnosed as RLVs by gray-scale and color Doppler ultrasonography and justified a wait-and-see strategy. Thirty-seven cases were followed until total recovery after delivery (follow-up rate 90.2%). Swelling with or without pain disappeared spontaneously postpartum. CONCLUSIONS RLVs are easily misdiagnosed as inguinal hernias and color Doppler of the inguinal area is the best examination for making the correct diagnosis. Conservative therapy for RLV is beneficial and safe when assured by color Doppler.

Abstract
INTRODUCTION Tacrolimus is an immunosuppressive medication for organ transplantation. FOXP3(+) T regulatory cells (Tregs) play roles in suppression of rejection and induction of graft tolerance. This study aimed to evaluate the correlation between the polymorphism of FOXP3 and the blood level of tacrolimus in renal transplant recipients. METHODS This retrospective study included 100 renal transplant recipients receiving tacrolimus treatment and 100 healthy control subjects. Genotyping for FOXP3 rs3761547 AA, AG, GG, rs3761548 AA, AC, CC and rs223236 AA, AG, GG was performed. Concentrations of tacrolimus, creatinine, and urea nitrogen levels in blood were measured. RESULTS Frequencies of genotypes of FOXP3 rs3761548 AA, AC, and CC, rs3761547 AA, AG, GG and rs 223236 AA, AG, GG in renal transplant recipients were similar to those in normal people. The blood level of tacrolimus in recipients with rs3761548 CC was significantly higher than that in recipients with rs3761548 AA and AC (P < .001). No difference in the blood level of tacrolimus was found in recipients with different genotypes of rs3761547 and rs223236. Compared to rs3761548 AA and AC groups, there was no difference of Modification of Diet in Renal Disease (MDRD) glomerular filtration rate and the level of blood urea nitrogen before transplantation; however, these 2 parameters were significantly improved after transplantation in the rs3761548 CC group. The level of tacrolimus was correlated positively with MDRD glomerular filtration rate and negatively with the blood urea nitrogen level in recipients with rs3761548 CC genotype after transplantation. CONCLUSIONS Our study identified a new relationship between FOXP3 rs3761548 and the blood level of tacrolimus. These results suggest that the polymorphism of FOXP3 may affect tacrolimus pharmacokinetics.

Abstract
Objective: To explore the clinical features and conduct prognostic analysis about visual recovery and relapse of neuromyelitisoptica (NMO) spectrum disease (NMOSD) with sjogren syndrome (SS). Methods: A retrospective and prospective observational study was conducted.Between July 2013 and June 2016, 172 patients with NMOSD (NMOSD-non SS: 116/172, 67.4%; NMOSD-SS: 56/172, 32.6%) were assessed at Beijing Tongren Hospital, Capital Medical University, Beijing, China.The prognostic factors of NMOSD-SS patients were also analyzed. Results: As compared with NMOSD-non SS patients, NMOSD-SS patients had worse visual impairment (percentage of patients with visual acuity less than 0.1, 83.9% vs 69.8%, P<0.05), higher positive rate of SSA (92.9% vs 0.0%, P<0.05), higher proportion of dryness of mouth and eye (66.1% vs 5.2%, P<0.05) as well as higher percentage of reduced visual evoked potential (VEP) amplitude (60.7% vs 43.1%, P<0.05). NMOSD-SS patients had a significantly higher average year recurrent frequency (0.58 vs 0.53) and significantly shorter mean recurrence time (6.7 months vs 12.4 months, P<0.05). The results showed that recurrent eyes, the worst visual acuities of onset less than 0.1 were independent risk factors of visual impairment (visual activity <0.1), according to at least six months' follow-up of all NMOSD-SS patients (OR=6.410 and 9.434, respectively, P<0.05). Meanwhile, immunosuppressive drugs were protective factors of relapse in NMOSD-SS patients (OR=0.107, P<0.05). Conclusions: NMOSD-SS patients have worse visual impairment, and they are more vulnerable to relapse than NMOSD-non SS patients, and the vision is lack of recovery for NMOSD-SS with recurrent eyes or the worst vision of onset less than 0.1.Immunosuppressive drugs can reduce the recurrence of NMOSD-SS relapse.

Abstract
Some studies have demonstrated that aging is associated with impaired vestibular reflexes, especially otolithic reflexes, resulting in postural instability. However, the neurochemical basis of these age-related changes is still poorly understood. The l-arginine metabolic system has been implicated in changes in the brain associated with aging. In the current study, we examined the levels of l-arginine and its metabolizing enzymes and downstream metabolites in the vestibular nucleus complex (VNC) and cerebellum (CE) of rats with and without behavioral testing which were young (4months old), middle-aged (12months old) or aged (24months old). We found that aging was associated with lower nitric oxide synthase activity in the CE of animals with testing and increased arginase in the VNC and CE of animals with testing. l-citrulline and l-ornithine were lower in the VNC of aged animals irrespective of testing, while l-arginine and l-citrulline were lower in the CE with and without testing, respectively. In the VNC and CE, aging was associated with lower levels of glutamate in the VNC, irrespective of testing. In the VNC it was associated with higher levels of agmatine and putrescine, irrespective of testing. In the CE, aging was associated with higher levels of putrescine in animals without testing and with higher levels of spermine in animals with testing, and spermidine, irrespective of testing. Multivariate analyses indicated significant predictive relationships between the different variables, and there were correlations between some of the neurochemical variables and behavioral measurements. Cluster analyses revealed that aging altered the relationships between l-arginine and its metabolites. The results of this study demonstrate that there are major changes occurring in l-arginine metabolism in the VNC and CE as a result of age, as well as behavioral activity.

Abstract
The formation of the mandibular condylar cartilage (MCC) and its subchondral bone is an important but understudied topic in dental research. The current concept regarding endochondral bone formation postulates that most hypertrophic chondrocytes undergo programmed cell death prior to bone formation. Under this paradigm, the MCC and its underlying bone are thought to result from 2 closely linked but separate processes: chondrogenesis and osteogenesis. However, recent investigations using cell lineage tracing techniques have demonstrated that many, perhaps the majority, of bone cells are derived via direct transformation from chondrocytes. In this review, the authors will briefly discuss the history of this idea and describe recent studies that clearly demonstrate that the direct transformation of chondrocytes into bone cells is common in both long bone and mandibular condyle development and during bone fracture repair. The authors will also provide new evidence of a distinct difference in ossification orientation in the condylar ramus (1 ossification center) versus long bone ossification formation (2 ossification centers). Based on our recent findings and those of other laboratories, we propose a new model that contrasts the mode of bone formation in much of the mandibular ramus (chondrocyte-derived) with intramembranous bone formation of the mandibular body (non-chondrocyte-derived).

Abstract
Hepatocyte death mainly includes apoptosis and necrosis and is a critical process in the pathophysiological mechanism of liver injury caused by various reasons. Recent studies have shown that key regulatory molecules in the inhibition of apoptosis such as caspase cannot be used as targets for inhibiting disease progression in clinical practice. In recent years, programmed necrosis mediated by receptor-interacting protein 3(RIP3)becomes a new hot research topic. It not only plays an important role in inducing inflammatory response, but also is closely regulated by intracellular signal factors, and it is a type of active cell death which can be interfered with. Compared with apoptosis, programmed necrosis is accompanied by the release of various inflammatory factors, which significantly affects local immune microenvironment. RIP3-mediated programmed necrosis has been taken seriously in many diseases. Although its mechanism of action in liver disease remains unclear, the results of recent studies confirmed its important role in the development of liver disease. This article reviews the research advances in the role of RIP3-mediated programmed necrosis signaling pathway in liver disease of various causes and investigates the possibility of RIP3-mediated programmed necrosis as a new target in the treatment of liver disease.

Abstract
Previous research implicates altered metabolism of l-arginine, a versatile amino acid with a number of bioactive metabolites, in the pathogenesis of schizophrenia. The present study, for we believe the first time, systematically compared the metabolic profile of l-arginine in the frontal cortex (Brodmann's area 8) obtained post-mortem from schizophrenic individuals and age- and gender-matched non-psychiatric controls (n=20 per group). The enzyme assays revealed no change in total nitric oxide synthase (NOS) activity, but significantly increased arginase activity in the schizophrenia group. Western blot showed reduced endothelial NOS protein expression and increased arginase II protein level in the disease group. High-performance liquid chromatography and liquid chromatography/mass spectrometric assays confirmed significantly reduced levels of γ-aminobutyric acid (GABA), but increased agmatine concentration and glutamate/GABA ratio in the schizophrenia cases. Regression analysis indicated positive correlations between arginase activity and the age of disease onset and between l-ornithine level and the duration of illness. Moreover, cluster analyses revealed that l-arginine and its main metabolites l-citrulline, l-ornithine and agmatine formed distinct groups, which were altered in the schizophrenia group. The present study provides further evidence of altered brain arginine metabolism in schizophrenia, which enhances our understanding of the pathogenesis of schizophrenia and may lead to the future development of novel preventions and/or therapeutics for the disease.

Abstract
GPRC5A is an orphan G-protein coupled receptor with an intriguing dual behavior, acting as an oncogene in some cancers and as a tumor suppressor in other cancers. In the pancreatic cancer context, very little is known about GPRC5A. By analyzing messenger RNA (mRNA) expression data from 675 human cancer cell lines and 10 609 samples from The Cancer Genome Atlas (TCGA) we found that GPRC5A's abundance in pancreatic cancer is highest (cell lines) or second highest (TCGA) among all tissues and cancer types. Further analyses of an independent set of 252 pancreatic normal and cancer samples showed GPRC5A mRNA to be more than twofold upregulated in primary tumor samples compared with normal pancreas (P-value<10−5), and even further upregulated in pancreatic cancer metastases to various organs (P-value=0.0021). Immunostaining of 208 cores (103 samples) of a tissue microarray showed generally low expression of GPRC5A protein in normal pancreatic ductal cells; on the other hand, in primary and metastatic samples, GPRC5A protein levels were dramatically increased in pancreatic ductal cells. In vitro studies of multiple pancreatic cancer cell lines showed that an increase in GPRC5A protein levels promoted pancreatic cancer cell growth and migration. Unexpectedly, when we treated pancreatic cancer cell lines with gemcitabine (2′,2′-difluorodeoxycytidine), we observed an increase in GPRC5A protein abundance. On the other hand, when we knocked down GPRC5A we sensitized pancreatic cancer cells to gemcitabine. Through further experimentation we showed that the monotonic increase in GPRC5A protein levels that we observe for the first 18 h following gemcitabine treatment results from interactions between GPRC5A's mRNA and the RNA-binding protein HuR, which is an established key mediator of gemcitabine's efficacy in cancer cells. As we discovered, the interaction between GPRC5A and HuR is mediated by at least one HuR-binding site in GPRC5A's mRNA. Our findings indicate that GPRC5A is part of a complex molecular axis that involves gemcitabine and HuR, and, possibly, other genes. Further work is warranted before it can be established unequivocally that GPRC5A is an oncogene in the pancreatic cancer context.

Abstract
Altered expression of long noncoding RNAs (lncRNAs) associated with human carcinogenesis. We performed a cDNA microarray analysis of lncRNA expression in 12 cases of nasopharyngeal carcinoma (NPC) and 4 non-tumor nasopharyngeal epitheliums. One lncRNA, actin filament associated protein 1 antisense RNA1 (AFAP1-AS1), was identified and selected for further study. AFAP1-AS1 expression was upregulated in NPC and associated with NPC metastasis and poor prognosis. In vitro experiments demonstrated that AFAP1-AS1 knockdown significantly inhibited the NPC cell migration and invasive capability. AFAP1-AS1 knockdown also increased AFAP1 protein expression. Proteomic and bioinformatics analyses suggested that AFAP1-AS1 affected the expression of several small GTPase family members and molecules in the actin cytokeratin signaling pathway. AFAP1-AS1 promoted cancer cell metastasis via regulation of actin filament integrity. AFAP1-AS1 might be a potential novel marker that can predict cancer patient prognosis and as a potential therapeutic target for NPC.

Abstract
WHAT IS KNOWN AND OBJECTIVE Thiopurine methyltransferase (TPMT) enzyme is an important component in the metabolism of azathioprine (AZA). Its mutation may lead to AZA-induced toxicity. The dysfunctional genetic variant TPMT *3C is of low frequency among Asians. Moreover, AZA-induced toxicity still occurs in some patients with normal TPMT activity. This suggests that additional factors, including other genetic variants, may contribute to such toxicity. Recent studies described a strong association between a variant of the NUDT15, a gene that mediates the hydrolysis of some nucleoside diphosphate derivatives, and thiopurine-related myelosuppression in Asians. We report the first case of a Chinese patient with AZA-induced severe toxicity with no clinically significant TPMT variant but with the NUDT15 c.415C>T allele. CASE SUMMARY A 40-year-old Chinese patient with PBC-AIH overlap syndrome had been receiving for one month, azathioprine (50 mg/day) and methylprednisolone (24 mg/day) based on his TPMT*3C wild-type genotype. The patient developed serious myelosuppression and hair loss. AZA was stopped, and the patient was given liver-protective drugs and supportive treatment. TPMT and NUDT15 gene sequencing suggests that NUDT15 c.415C>T mutation was the likely cause of the adverse reaction. WHAT IS NEW AND CONCLUSION NUDT15 c.415C>T may be another predictor of AZA-induced leukocytopenia. If further well-controlled studies validate this association with sufficient predictive power, NUDT15 and TPMT genotyping before starting AZA treatment may become appropriate.

Abstract
Emerging data demonstrate promising results of related haploidentical allogeneic hematopoietic stem cell transplantation (haplo-HCT) for the treatment of hematologic malignancies. Data about G-CSF primed PBSC as reliable source of graft with myeloablative conditioning are lacking. We updated the outcomes in 130 adult patients with high-risk hematologic malignancies who received haplo-PBSC transplantation consecutively under busulfan-based conditioning. PBSC were freshly isolated and infused without ex vivo T-cell depletion into the recipients. Myeloid recovery was achieved in 99.2% patients with full donor chimerism. The cumulative incidence of acute grade 3-4 GvHD, overall and extensive chronic GvHD was 14.9%, 38.6% and 16.5%, respectively. The 3-year non-relapse mortality rate was 24.1%. Non-remission prior to transplant was associated with higher incidence of relapse (P=0.006), inferior overall survival (P=0.017) and leukemia-free survival (P=0.024). These data suggest that PBSC is a reliable graft source in haploidentical, unmanipulated transplant settings under myeloablative conditioning in patients with high-risk hematologic malignancies.

Abstract
PURPOSE To explore the trend of progression and regression of peripheral neuropathy (PN) induced by combination of carboplatin and paclitaxel, and the impacts on daily activities. MATERIALS AND METHODS PN was evaluated by nurse-based interview and patient-reported measures in their diary. The severity of PN scaled by National Cancer Institute Common Toxicity Criteria (NCI-CTC) before each cycle of chemotherapy and at three, six, and 12 months after drug withdrawal and coded as Grade I - V. RESULTS The authors enrolled 106 eligible patients with ovarian cancer who underwent six cycles of combined chemotherapy of carboplatin plus paclitaxel. No patients showed Grade IV and V of PN and it was gradually aggravated following the dose accumulation. About 29.3% of the patients presented no PN, 64.2% Grade I, and 6.6% Grade II after the third course of chemotherapy, but increased to 36.8% of Grade I, 25.5% of Grade II, and 34.9% of Grade III after the sixth course of chemotherapy. At one-year follow-up, the rate of PN still existed with the rate of 88.5%, 57.3%, and 38.7% at three, six, and 12 months after drug withdrawal. Thirty-one patients encountered accidents, such as sharp injury (14.2%), fall (9.4%), burn (3.8%), and cold injury (1.9%). CONCLUSIONS A significant proportion of patients with epithelial ovarian cancer treated with carboplatin plus paclitaxel suffer long term neuropathy and it affects patient's daily activities. Specialized care is necessary to provide not only during treatment, but also months to years after drugs withdrawal.

Abstract
The integration of controlled growth factor delivery and biomimetic architecture into a microsphere is a challenging but attractive strategy for developing new injectable biomaterials. In this work, a unique hierarchical nanosphere-encapsulated-in-microsphere scaffolding system is developed. First, heparin-conjugated gelatin (HG) is synthesized, which provides binding domains for bone morphogenetic protein 2 (BMP2) to stabilize this growth factor, protect it from denaturation and proteolytic degradation, and subsequently prolong its sustained release. Next, a unique approach is developed which includes a water-in-oil-in-oil double emulsion process and a thermally induced phase separation to encapsulate BMP2-binding HG nanospheres into nanofibrous microspheres. The nanofibrous microsphere is self-assembled from synthetic nanofibers, and has superior surface area, high porosity, low density, and is an excellent carrier to support cell adhesion and tissue in-growth. BMP2 in the hierarchical microsphere is released in a multiple-controlled manner by the binding with heparin and encapsulation of the nanosphere and microsphere. An in vivo calvarial defect model confirms that this microsphere is an excellent osteoinductive scaffold for enhanced bone regeneration. By choosing different growth factors, this hierarchical microsphere system can easily be applied to other types of tissue regeneration. The work expands the ability to develop new injectable biomaterials for advanced regenerative therapies.

Abstract
Adrenergic, alpha-1B-, receptor (ADRA1B) and peroxisome proliferator-activated receptor gamma, coactivator 1 beta (PPARGC1B) genes are involved in regulation of hen ovarian development. In this study, these two genes were investigated as possible molecular markers associated with hen-housed egg production, egg weight (EW) and body weight in Chinese Dagu hens. Samples were analyzed using the polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) technique, followed by sequencing analysis. Two novel single nucleotide polymorphisms (SNPs) were identified within the candidate genes. Among them, an A/G transition at base position 1915 in exon 2 of ADRA1B gene and a T/C mutation at base position 6146 in the 3′-untranslated region (UTR) of PPARGC1B gene were found to be polymorphic and named SNP A1915G and T6146C, respectively. The SNP A1915G (ADRA1B) leads to a non-synonymous substitution (aspartic acid 489-to-glycine). The 360 birds from the Dagu population were divided into genotypes AA and AG, allele A was found to be present at a higher frequency. Furthermore, the AG genotype correlated with significantly higher hen-housed egg production (HHEP) at 30, 43, 57, and 66 wks of age and with a higher EW at 30 and 43 wks (p<0.05). For the SNP T6146C (PPARGC1B), the hens were typed into TT and TC genotypes, with the T allele shown to be dominant. The TC genotype was also markedly correlated with higher HHEP at 57 and 66 wks of age and EW at 30 and 43 wks (p<0.05). Moreover, four haplotypes were reconstructed based on these two SNPs, with the AGTC haplotype found to be associated with the highest HHEP at 30 to 66 wks of age and with higher EW at 30 and 43 wks (p<0.05). Collectively, the two SNPs identified in this study might be used as potential genetic molecular markers favorable in the improvement of egg productivity in chicken breeding.

Abstract
During the normal aging process, the brain undergoes a range of biochemical and structural alterations, which may contribute to deterioration of sensory and cognitive functions. Age-related deficits are associated with altered efficacy of synaptic neurotransmission. Emerging evidence indicates that levels of agmatine, a putative neurotransmitter in the mammalian brain, are altered in a region-specific manner during the aging process. The gross tissue content of agmatine in the prefrontal cortex (PFC) of aged rat brains is decreased whereas levels in the temporal cortex (TE) are increased. However, it is not known whether these changes in gross tissue levels are also mirrored by changes in agmatine levels at synapses and thus could potentially contribute to altered synaptic function with age. In the present study, agmatine levels in presynaptic terminals in the PFC and TE regions (300 terminals/region) of young (3month; n=3) and aged (24month; n=3) brains of male Sprague-Dawley rats were compared using quantitative post-embedding immunogold electron-microscopy. Presynaptic levels of agmatine were significantly increased in the TE region (60%; p<0.001) of aged rats compared to young rats, however no significant differences were detected in synaptic levels in the PFC region. Double immunogold labeling indicated that agmatine and glutamate were co-localized in the same synaptic terminals, and quantitative analyses revealed significantly reduced glutamate levels in agmatine-immunopositive synaptic terminals in both regions in aged rats compared to young animals. This study, for the first time, demonstrates differential effects of aging on agmatine and glutamate in the presynaptic terminals of PFC and TE. Future research is required to understand the functional significance of these changes and the underlying mechanisms.

Abstract
Transcription factor forkhead box L2 (FOXL2) and growth differentiation factor-9 (GDF9) genes have critical roles in the regulation of hen ovarian development. In the present study, these genes were explored as possible molecular markers associated with BW, hen-housed egg production, and egg weight in Chinese Dagu hens. Samples were analyzed using the PCR-single strand conformation polymorphism (PCR-SSCP) technique followed by sequencing analysis, and two novel single nucleotide polymorphisms (SNPs) were identified within these candidate genes. Among them, an A/G transition at base position 238 in the coding region of the FOXL2 gene and a G/T transversion at base position 1609 in exon 2 of the GDF9 gene were found to be polymorphic and named SNPs A238G and G1609T, respectively. The SNP A238G (FOXL2) leads to a nonsynonymous substitution (isoleucine77-to-valine), and when the 360 Dagu hen samples were divided into genotypes AA and AB, allele A was found to be present at a higher frequency. Furthermore, the AA genotype correlated with significantly higher hen-housed egg production at 30, 43, 57, and 66 wk of age and with a higher egg weight at 43 wk (P<0.05). For the SNP G1609T (GDF9), the hens were typed into TT and TC genotypes, with the T allele shown to be dominant. The TC genotype was also markedly correlated with higher hen-housed egg production and a higher egg weight (P<0.05). Moreover, four haplotypes were reconstructed based on these two SNPs, with the AATC haplotype found to be correlated with the highest hen-housed egg production at 30 to 66 wk of age and with higher egg weights at 43 wk (P<0.05). Collectively, the two SNPs identified in this study might be used as possible genetic molecular markers to aid in the improvement of egg production traits in chicken breeding.

Abstract
For decades, it has been widely accepted that hypertrophic chondrocytes undergo apoptosis prior to endochondral bone formation. However, very recent studies in long bone suggest that chondrocytes can directly transform into bone cells. Our initial in vivo characterization of condylar hypertrophic chondrocytes revealed modest numbers of apoptotic cells but high levels of antiapoptotic Bcl-2 expression, some dividing cells, and clear alkaline phosphatase activity (early bone marker). Ex vivo culture of newborn condylar cartilage on a chick chorioallantoic membrane showed that after 5 d the cells on the periphery of the explants had begun to express Col1 (bone marker). The cartilage-specific cell lineage-tracing approach in triple mice containing Rosa 26(tdTomato) (tracing marker), 2.3 Col1(GFP) (bone cell marker), and aggrecan Cre(ERT2) (onetime tamoxifen induced) or Col10-Cre (activated from E14.5 throughout adult stage) demonstrated the direct transformation of chondrocytes into bone cells in vivo. This transformation was initiated at the inferior portion of the condylar cartilage, in contrast to the initial ossification site in long bone, which is in the center. Quantitative data from the Col10-Cre compound mice showed that hypertrophic chondrocytes contributed to ~80% of bone cells in subchondral bone, ~70% in a somewhat more inferior region, and ~40% in the most inferior part of the condylar neck (n = 4, P < 0.01 for differences among regions). This multipronged approach clearly demonstrates that a majority of chondrocytes in the fibrocartilaginous condylar cartilage, similar to hyaline cartilage in long bones, directly transform into bone cells during endochondral bone formation. Moreover, ossification is initiated from the inferior portion of mandibular condylar cartilage with expansion in one direction.

Abstract
The SLIT/Roundabout (ROBO) pathway is involved in follicle development of mammalian ovary, and 2 secreted hormones activin A and inhibin A have potential roles in modulation of the SLIT/ROBO system, but the related actions remain poorly understood in bird. The aims of the present study were to examine the spatial and temporal expression of the SLIT ligand genes (SLIT1, SLIT2, and SLIT3) and their receptor ROBO1, ROBO2, ROBO3, and ROBO4 genes in various-sized prehierarchical follicles during hen ovary development and the effects of activin A and inhibin A on the expression of these genes in the cultured hen follicles. Our result demonstrated that the transcripts of the 3 SLIT genes were highly expressed in the developing follicles and expression patterns of the SLIT transcripts were different from those of ROBO genes detected by real-time quantitative reverse transcriptase PCR. Both SLIT and ROBO transcripts were predominantly expressed in oocytes and granulosa cells from the prehierarchichal follicles examined by in situ hybridization. The localization for SLIT and ROBO proteins was revealed by immunohistochemistry similar to the spatial distribution of their transcript. In cultured follicles (4 to 8 mm in diameter), the expression levels of SLIT and ROBO members are hormonally regulated by activin A (10 ng/mL) and/or inhibin A (20 ng/mL) after treatment for 24 h. However, the expression of only SLIT2, SLIT3, and ROBO3 mRNA presented a directly opposite response to activin A and inhibin A hormones. These results indicate that SLIT/ROBO pathway is implicated in the prehierarchical follicular development of the hen ovary by an intrafollicular autocrine and/or paracrine action, and is influenced by activin A and inhibin A hormones.
