Abstract
BACKGROUND Peritoneal dialysis is a commonly used treatment for chronic kidney failure patients. Studies have shown that long-term peritoneal dialysis can lead to various degrees of malnutrition. Therefore, it is of great significance to improve the nutritional conditions of patients with peritoneal dialysis. This retrospective cohort study aimed to evaluate the clinical effects of intensive nutritional nursing combined with a 3-day diet diary intervention on the nutritional condition of peritoneal dialysis patients. METHODS In total, 163 patients were included in this study and, after 6 months of intervention, their nutritional and biochemical indicators, body weight, body mass index (BMI) and intake of dietary ingredients were analysed. RESULTS After the intervention, patients' serum albumin, haemoglobin, prealbumin, body weight, BMI and cholesterol levels were significantly increased (p < 0.05). Also, the daily energy and protein intake were significantly increased, whereas phosphorus intake was decreased (p < 0.05). Of note, the effective rate of intervention was 63.8%, respectively. We also found that factors such as the patient's age, education degree, income level and peritoneal dialysis age were the risk factors associated with malnutrition. Moreover, patients younger than 55 years old, with dialysis age younger than 5 years, unmarried/divorced and high school graduates, had higher chances of effective intervention, whereas the possibility of effective intervention was lower when the per capita monthly household income was less than 4000 Yuan. CONCLUSIONS In conclusion, intensive nutritional nursing combined with a 3-day dietary diary intervention can significantly improve the nutritional condition and optimise the diet structure of peritoneal dialysis patients with malnutrition. These findings provide evidence for healthcare providers to develop personalised interventions to address malnutrition in this population.

Abstract
Background Although favorable outcomes have been reported with radiofrequency ablation (RFA) for secondary hyperparathyroidism (SHPT), the long-term efficacy remains insufficiently investigated. Purpose To evaluate the long-term efficacy and safety of US-guided percutaneous RFA in patients with SHPT undergoing dialysis and to identify possible predictors associated with treatment failure. Materials and Methods This retrospective study included consecutive patients with SHPT with at least one enlarged parathyroid gland accessible for RFA who were undergoing dialysis at seven tertiary centers from May 2013 to July 2022. The primary end point was the proportion of patients with parathyroid hormone (PTH) levels less than or equal to 585 pg/mL at the end of follow-up. Secondary end points were the proportion of patients with normal calcium and phosphorus levels, the technical success rate, procedure-related complications, and improvement in self-rated hyperparathyroidism-related symptoms (0-3 ranking scale). The Wilcoxon signed rank test and generalized estimating equation model were used to evaluate treatment outcomes. Univariable and multivariable regression analyses identified variables associated with treatment failure (recurrent or persistent hyperparathyroidism). Results This study included 165 patients (median age, 51 years [IQR, 44-60 years]; 92 female) and 582 glands. RFA effectively reduced PTH, calcium, and phosphorus levels, with targeted ranges achieved in 78.2% (129 of 165), 72.7% (120 of 165), and 60.0% (99 of 165) of patients, respectively, at the end of follow-up (mean, 51 months). For the RFA sessions, the technical success rate was 100% (214 of 214). Median symptom scores (ostealgia, arthralgia, pruritus) decreased (all P < .001). Regarding complications, only hypocalcemia (45.8%, 98 of 214) was common. Treatment failure occurred in 36 patients (recurrent [n = 5] or persistent [n = 31] hyperparathyroidism). The only potential independent predictor of treatment failure was having less than four treated glands (odds ratio, 17.18; 95% CI: 4.34, 67.95; P < .001). Conclusion US-guided percutaneous RFA was effective and safe in the long term as a nonsurgical alternative for patients with SHPT undergoing dialysis; the only potential independent predictor of treatment failure was a lower number (<4) of treated glands. © RSNA, 2024 Supplemental material is available for this article.

Abstract
BACKGROUND Reoperation for recurrent or persistent secondary hyperparathyroidism (SHPT) after parathyroidectomy is challenging due to surgical scars and postoperative adhesions. Therefore, there is an increasing need to develop a new minimally invasive therapy. OBJECTIVE To analyze the efficacy of ultrasound (US)-guided radiofrequency ablation (RFA) in patients with recurrent or persistent SHPT after parathyroidectomy. PATIENTS AND METHODS From March 2013 to January 2022, 20 enlarged parathyroid glands in 10 patients with recurrent or persistent SHPT were treated with US-guided RFA. The levels of serum intact parathyroid hormone (iPTH), calcium (Ca), phosphorus (P), and alkaline phosphatase (ALP), as well as clinical symptoms, were compared before and after RFA. The ablation procedure-related complications were also evaluated. The target range for iPTH levels was approximately 2-9 times the upper limit of normal (130-585 pg/mL). RESULTS The mean follow-up time was 49.6 ± 34.5 months (range from 6 to101 months). The levels of serum iPTH, Ca, and P decreased significantly one day post-ablation. Six months after RFA, 70% of patients reached the targets for iPTH, and 50% of patients reached targets at the end of follow-up. Two patients underwent repeat ablation at 9 months and 6 years after RFA, respectively, due to persistently elevated iPTH levels, and both had serum iPTH concentrations in the recommended range at the recent follow-up visit. The patients' clinical symptoms significantly improved after ablation. Major complications after RFA included hoarseness (2/10) and permanent hypoparathyroidism (1/10). Severe hypocalcemia occurred in four patients (4/10) after ablation. CONCLUSION US-guided percutaneous RFA for recurrent or persistent SHPT is safe, efficacious, and repeatable, and can significantly improve hyperparathyroidism-related symptoms.

Abstract
OBJECTIVE To prospectively evaluate the outcomes of ultrasound (US)-guided radiofrequency ablation (RFA) in tertiary hyperparathyroidism (THPT). MATERIALS AND METHODS Patients with THPT underwent RFA between September 2017 and January 2022. Laboratory parameters, including serum intact parathyroid hormone (iPTH) levels, were monitored for 48 months after RFA and compared with the levels at baseline. Complications related to RFA and changes in hyperparathyroidism-related clinical symptoms were recorded before and after RFA. RESULTS A total of 42 patients with THPT were recruited for this study. Ultimately, 36 patients with renal failure and 2 patients who underwent successful renal transplantation (male:female, 17:21; median age, 54.5 years) were enrolled. The follow-up time was 21.5 ± 19.0 months in the 36 patients with renal failure. In these 36 patients, iPTH levels were significantly decreased to 261.1 pg/mL at 48 months compared with the baseline value of 1284.9 pg/mL (P = 0.012). Persistent hyperparathyroidism, defined as iPTH levels maintained at > 585.0 pg/mL for 6 months after treatment, occurred in 4.0% of patients (1/25). Recurrent hyperparathyroidism, defined as iPTH levels > 585.0 pg/mL after 6 months, were 4.0% (1/25) and 0.0% (0/9) at 6 months and 4 years after treatment, respectively. In two patients with THPT after successful renal transplantation, iPTH decreased from the baseline value of 242.5 and 115.9 pg/mL to 171.0 and 62.0 pg/mL at 6 months after treatment. All complications resolved within 6 months of ablation without medical intervention, except in 10.5% (4/38) patients with permanent hypocalcemia. The overall symptom recovery rate was 58.8% (10/17). The severity scores for bone pain, arthralgia, and itchy skin associated with hyperparathyroidism improved after treatment (P < 0.05). CONCLUSION US-guided RFA is an effective and safe alternative to surgery in the treatment of patients with TPTH and improves hyperparathyroidism-related clinical symptoms.

Abstract
Antipsychotic medications are commonly used to treat schizophrenia, but they can have negative effects on lipid metabolism, leading to an increased risk of cardiovascular diseases, reduced life expectancy, and difficulties with treatment adherence. The specific mechanisms by which antipsychotics disrupt lipid metabolism are not well understood. Sterol regulatory element-binding proteins (SREBPs) are important transcriptional factors that regulate lipid metabolism. Proprotein convertase subtilisin/kexin type 9 (PCSK9), a gene regulated by SREBPs, plays a critical role in controlling levels of low-density lipoprotein cholesterol (LDL-C) and has become a focus of research on lipid-lowering drugs. Recent studies have shown that antipsychotic drugs can affect lipid metabolism through the SREBP/PCSK9 pathway. A deep understanding of the mechanism for this pathway in antipsychotic drug-related metabolic abnormalities will promote the prevention of lipid metabolism disorders in patients with schizophrenia and the development and application of new drugs.

Abstract
Neuroinflammation plays an important role in the pathogenesis of neurological disorders, and despite intensive research, treatment of neuroinflammation remains limited. BaiXiangDan capsule (BXD) is widely used in clinical practice. However, systematic studies on the direct role and mechanisms of BXD in neuroinflammation are still lacking. We systematically evaluated the potential pharmacological mechanisms of BXD on neuroinflammation using network pharmacological analysis combined with experimental validation. Multiple databases are used to mine potential targets for bioactive ingredients, drug targets and neuroinflammation. GO and KEGG pathway analysis was also performed. Interactions between active ingredients and pivotal targets were confirmed by molecular docking. An experimental model of neuroinflammation was used to evaluate possible therapeutic mechanisms for BXD. Network pharmacological analysis revealed that Chrysoeriol, Kaempferol and Luteolin in BXD exerted their anti-neuroinflammatory effects mainly by acting on targets such as NCOA2, PIK3CA and PTGS2. Molecular docking results showed that their average affinity was less than -5 kcal/mol, with an average affinity of -8.286 kcal/mol. Pathways in cancer was found to be a potentially important pathway, with involvement of PI3K/AKT signaling pathways. In addition, in vivo experiments showed that BXD treatment ameliorated neural damage and reduced neuronal cell death. Western blotting, RT-qPCR and ELISA analysis showed that BXD inhibited not only the expression of IL-1β, TNF-α and NO, but also NF-κB, MMP9 and PI3K/AKT signaling pathways. This study applied network pharmacology and in vivo experiments to explore the possible mechanisms of BXD against neuroinflammation, providing insight into the treatment of neuroinflammation.

Abstract
Background: Aggressive behaviors are one of the most important negative behaviors that seriously endangers human health. Also, the central para-inflammation of microglia triggered by stress can affect neurological function, plasticity, and behavior. NLRP3 integrates stress-related signals and is a key driver of this neural para-inflammation. However, it is unclear whether the NLRP3 inflammasome is implicated in the development of aggressive behaviors. Methods: First, aggressive behavior model mice were established using the resident intruder paradigm. Then, aggressive behaviors were determined with open-field tests (OFT), elevated plus-maze (EPM), and aggressive behavior tests (AT). Moreover, the expression of P2X7R and NLRP3 inflammasome complexes were assessed by immunofluorescence and Western blot. The levels of NLRP3 and inflammatory cytokines were evaluated using enzyme-linked immunosorbent assay (ELISA) kits. Finally, nerve plasticity damage was observed by immunofluorescence, transmission electron microscope, and BrdU staining. Results: Overall, the resident intruder paradigm induced aggressive behaviors, activated the hippocampal P2X7R and NLRP3 inflammasome, and promoted the release of proinflammatory cytokines IL-1β in mice. Moreover, NLRP3 knockdown, administration of P2X7R antagonist (A804598), and IL-1β blocker (IL-1Ra) prevented NLRP3 inflammasome-driven inflammatory responses and ameliorated resident intruder paradigm-induced aggressive behaviors. Also, the resident intruder paradigm promoted the activation of mouse microglia, damaging synapses in the hippocampus, and suppressing hippocampal regeneration in mice. Besides, NLRP3 knockdown, administration of A804598, and IL-1Ra inhibited the activation of microglia, improved synaptic damage, and restored hippocampal regeneration. Conclusion: The NLRP3 inflammasome-driven inflammatory response contributed to resident intruder paradigm-induced aggressive behavior, which might be related to neuroplasticity. Therefore, the NLRP3 inflammasome can be a potential target to treat aggressive behavior-related mental illnesses.

Abstract
PURPOSE Secondary hyperparathyroidism (SHPT) is a frequently encountered problem in patients with end-stage renal disease (ESRD) prior to renal transplantation (RTP), and the successful management of SPHP currently is challenging. In this study, we aimed to investigate the effectiveness of radiofrequency ablation (RFA) for SHPT as a bridge to RTP and to evaluate post-transplantation outcomes. METHODS Patients with SHPT receiving RFA treatment were retrospectively reviewed, and those underwent RTP after ablation were enrolled. Serum parathyroid hormone (PTH), calcium, and phosphate levels were collected before ablation and at follow-up periods. The primary endpoints are PTH values at time of transplantation and at the final follow-up. The secondary endpoints were RFA-related complications, serum calcium and phosphate concentrations, and allograft function. RESULTS Eleven patients with 43 enlarged parathyroid glands were treated with 16 RFA sessions and enrolled in the study. Complete ablation was achieved in all glands with transient hoarseness and hypocalcemia occurring in two and five of the treatments, respectively. At time of transplantation, serum PTH levels (246.7 ± 182.6 pg/mL) were significantly lower than that before RFA (1666.55 ± 874.48 pg/mL, p < 0.001) and were all within guideline-oriented range. The median follow-up period was 57.2 months. At last visit, all patients were alive, with normal PTH values and functioning grafts. CONCLUSIONS Ultrasound-guided RFA is effective for destroying hyperplastic parathyroid tissues in SHPT patients, whose PTH values fall within the guideline-oriented range both pre-and post-transplantation. Percutaneous RFA acts as an effective bridge to RTP and might provide a new management paradigm designed to improve post-transplant outcomes.

Abstract
BACKGROUND Genetic association studies have demonstrated that the SNP rs12603332 located on chromosome 17q21 is highly associated with the risk of the development of asthma. METHODS To determine whether SNP rs1260332 is functional in regulating levels of ORMDL3 expression, we used a Cytosine Base Editor (CBE) plasmid DNA or a CBE mRNA to edit the rs12603332 C risk allele to the T non-risk allele in a human lymphocyte cell line (i.e., Jurkat cells) and in primary human CD4 T cells that carry the C risk alleles. RESULTS Jurkat cells with the rs12603332 C risk allele expressed significantly higher levels of ORMDL3 mRNA, as well as the ORMDL3 regulated gene ATF6α as assessed by qPCR compared to Jurkat clones with the T non-risk allele. In primary human CD4 T cells, we edited 90 ± 3% of the rs12603332-C risk allele to the T non-risk allele and observed a reduction in ORMDL3 and ATF6α expression. Bioinformatic analysis predicted that the non-risk allele rs12603332-T could be the central element of the E-box binding motif (CANNTG) recognized by the E47 transcription factor. An EMSA assay confirmed the bioinformatics prediction demonstrating that a rs12603332-T containing probe bound to the transcription factor E47 in vitro. CONCLUSIONS SNP rs12603332 is functional in regulating the expression of ORMDL3 as well as ORMDL3 regulated gene ATF6α expression. In addition, we demonstrate the use of CBE technology in functionally interrogating asthma-associated SNPs using studies of primary human CD4 cells.

Abstract
AIM Epilepsy is a common and serious neurological disease that causes recurrent episodes, but its molecular mechanism remains unclear. Abnormal miRNA expression is associated with epilepsy, including miR-451. This research investigated the role of miR-451 in seizure and its detailed mechanism. METHODS The seizure mice model was induced by kainic acid (KA) injection to the right lateral cerebral ventricle. Behavioral changes in mice were observed and evaluated by the Racine Scale. The miR-451 knockout mice were established by adenovirus infection. The in vitro model was performed by miR-451 mimics transfected HEK-293 cells. The amount of neuronal death and morphological changes were evaluated by Nissl staining and H&E staining. RESULTS The results showed that miR-451 is up regulated in KA-induced seizure models and miR- 451 knockout decreased the behavior score and improved the pathological changes of the hippocampus. Besides, MiR-451 knockout inhibited the apoptosis of hippocampal neurons. Bioinformatics studies have shown that glial cell line-derived neurotrophic factor (GDNF) is a target gene of miR-451. MiR-451 could negatively regulate the expression of GDNF. GDNF overexpression could reverse the effect of miR-451 on KA induced brain injury and neuronal apoptosis. CONCLUSION This research demonstrates that miR-451 can affect the behavior of KA-induced epilepsy mice and hippocampal neuronal damage by regulating GDNF expression. The results would provide an experimental foundation for further research about the potential contribution of mi- RNAs to epilepsy pathophysiology.

Abstract
ORM1-like 3 (ORMDL3) has strong genetic linkage to childhood onset asthma. To determine whether ORMDL3 selective expression in airway smooth muscle (ASM) influences ASM function, we used Cre-loxP techniques to generate transgenic mice (hORMDL3Myh11eGFP-cre), which express human ORMDL3 selectively in smooth muscle cells. In vitro studies of ASM cells isolated from the bronchi of hORMDL3Myh11eGFP-cre mice demonstrated that they developed hypertrophy (quantitated by FACS and image analysis), developed hyperplasia (assessed by BrdU incorporation), and expressed increased levels of tropomysin proteins TPM1 and TPM4. siRNA knockdown of TPM1 or TPM4 demonstrated their importance to ORMDL3-mediated ASM proliferation but not hypertrophy. In addition, ASM derived from hORMDL3Myh11eGFP-cre mice had increased contractility to histamine in vitro, which was associated with increased levels of intracellular Ca2+; increased cell surface membrane Orai1 Ca2+ channels, which mediate influx of Ca2+ into the cytoplasm; and increased expression of ASM contractile genes sarco/endoplasmic reticulum Ca2+ ATPase 2b and smooth muscle 22. In vivo studies of hORMDL3Myh11eGFP-cre mice demonstrated that they had a spontaneous increase in ASM and airway hyperreactivity (AHR). ORMDL3 expression in ASM thus induces changes in ASM (hypertrophy, hyperplasia, increased contractility), which may explain the contribution of ORMDL3 to the development of AHR in childhood onset asthma, which is highly linked to ORMDL3 on chromosome 17q12-21.

Abstract
RATIONALE Hypoglycemia, which is characterized mainly by palpitations, dizziness, and sweating, is common and easy to identify. However, some other symptoms, such as mental disorder or abnormal behavior, are atypical, which may lead to a misdiagnosis of epilepsy, sleepwalking, infarction, or mental disorder, among others. PATIENT CONCERNS We report a case of a patient with type 2 diabetes who presented with abnormal nocturnal behavior due to hypoglycemia. DIAGNOSIS Hypoglycemia was diagnosed based on a blood glucose level of 2.1 mmol/L when the patient turned up disoriented unresponsive, unable to understand what was said to him, and producing nonsensical speech. After the patient ate a piece of chocolate, his consciousness returned to normal and all mental symptoms disappeared. Polysomnography (PSG) was synchronously performed. The results of the PSG did not show any signs of abnormality during nonrapid eye movement (NREM) or rapid eye movement (REM) sleep. INTERVENTIONS We regulated his dose of insulin. OUTCOMES No additional episodes occurred during the 3-month follow-up. Therefore, the abnormal nocturnal behavior of this patient was determined to be due to hypoglycemia, while the cause of the hypoglycemia was insulin overuse. LESSONS For physicians, if the cause of abnormal behavior cannot be detected, hypoglycemia should be suspected. Long-term persistent hypoglycemia may cause brain dysfunction and even result in permanent brain damage.

Abstract
Previous studies have demonstrated that total flavonoid extracts from Caragana sinica (TFC) exert multiple therapeutic effects, promote blood flow, and exhibit anti-inflammatory and antioxidant properties. The present study aimed to investigate whether TFC promotes angiogenesis and exerts neuroprotective effects in a rat model of transient middle cerebral artery occlusion (tMCAO). Male Wistar rats were subjected to tMCAO for 1.5 h, followed by 24 h of reperfusion. TFC (15, 30, 60 mg/kg) was administered for 14 days. Evaluations of neurological function were performed following reperfusion, and infarct volumes were assessed in brain slices stained with 2,3,5-triphenyltetrazolium chloride (TTC). Our results indicated that TFC significantly attenuated cerebral infarct volume and neurological deficits following tMCAO. Laser Doppler, micro-PET/CT, and MRI analyses further demonstrated that TFC reduced infarct volume and enhanced cerebral blood flow in a dose-dependent manner, with the most significant effects occurring at a concentration of 60 mg/kg. Significant up-regulation of CD31, VEGF, Ang-1, HIF-1α, delta-like 4 (Dll4), and Notch1 expression was also observed in the experimental groups, relative to that in the vehicle group. In summary, the results of the present study indicate that TFC (15, 30, 60 mg/kg) attenuates neurological deficits, reduces infarct volume, and promotes angiogenesis following MCAO in a concentration-dependent manner, likely via increases in the expression of CD31, VEGF, Ang-1, HIF-1α, Dll4, and Notch1. Further studies are required to determine the clinical usefulness and potential mechanisms of TFC in patients with cerebral focal ischemic stroke.

Abstract
BACKGROUND Peritoneal dialysis (PD) is well-established as renal replacement therapy in end stage renal disease and has survival rates similar or better than hemodialysis (HD) for the initial years on dialysis therapy. However retention rate is lower due to higher technique failure rates than in HD and few patients stay on PD for more than 10 years (PD>10 yrs). Here we investigated clinical features characterizing PD>10 yrs patients. PATIENTS AND METHODS In a single center study of 450 prevalent PD patients, 35 PD>10 yrs patients (n=35) were compared with patients (n=415) who had been on PD for shorter periods of time in terms of clinical characteristics. Peritoneal transport, blood pressure, solute clearance, nutrition status, and blood calcium, phosphate and parathyroid hormone levels were measured dialysis start and, in PD>10 yrs patients, also after 5 and 10 years of PD. RESULTS The PD>10 yrs patients differed from the other PD patients in that (1) the proportion of women was higher; (2) body mass index (BMI) was lower; (3) there was no patient with diabetic nephropathy as primary diagnosis; (4) the incidence of peritonitis was lower; (5) glomerular filtration rate was higher; and (6) parathyroid hormone (PTH) levels were lower in those with decade-long PD treatment. In PD>10 yrs patients, serum albumin was maintained at a high level throughout the 10 year follow up; hemoglobin levels after 5 and 10 years of PD were higher than at the beginning of the treatment; blood calcium and phosphate concentrations were maintained at acceptable levels; while the dialysate/plasma ratio of creatinine, D/P-value, increased during the decade-long PD treatment. CONCLUSIONS Patients receiving PD>10 years had lower incidence of peritonitis, lower BMI, adequate control of blood calcium and phosphate levels and solute clearance, and were more often women than PD patients treated for shorter periods of time.

Abstract
BACKGROUND The purpose of this study was to determine if ultrasound-guided radiofrequency ablation (RFA) of hyperplastic parathyroid glands could be used to treat secondary hyperparathyroidism (HPT) in patients with chronic kidney disease. METHODS RFA of the hyperplastic parathyroid glands was performed in 34 patients with secondary HPT. Intact parathyroid hormone (iPTH), calcium, and phosphorus were measured. The outcome was based on the ablation extent (ie, 4, 3, and 1-2 glands). RESULTS The iPTH, calcium, and phosphorus levels decreased in all groups after RFA. One year after ablation, these parameters remained significantly lower in the 4-gland ablation group compared with the 3-gland and 1 to 2-gland groups. The same tendency was observed for the symptom score. The iPTH levels of <272 pg/mL on the day after ablation was the best predictor for maintaining parathyroid hormone (PTH) levels in a reasonable range 1 year after ablation. CONCLUSIONS RFA of hyperplastic parathyroid glands for treating secondary HPT is feasible in selected patients. © 2016 Wiley Periodicals, Inc. Head Neck 39: 564-571, 2017.

Abstract
BACKGROUND The transfer of fresh embryos is generally preferred over the transfer of frozen embryos for in vitro fertilization (IVF), but some evidence suggests that frozen-embryo transfer may improve the live-birth rate and lower the rates of the ovarian hyperstimulation syndrome and pregnancy complications in women with the polycystic ovary syndrome. METHODS In this multicenter trial, we randomly assigned 1508 infertile women with the polycystic ovary syndrome who were undergoing their first IVF cycle to undergo either fresh-embryo transfer or embryo cryopreservation followed by frozen-embryo transfer. After 3 days of embryo development, women underwent the transfer of up to two fresh or frozen embryos. The primary outcome was a live birth after the first embryo transfer. RESULTS Frozen-embryo transfer resulted in a higher frequency of live birth after the first transfer than did fresh-embryo transfer (49.3% vs. 42.0%), for a rate ratio of 1.17 (95% confidence interval [CI], 1.05 to 1.31; P=0.004). Women who underwent frozen-embryo transfer also had a lower frequency of pregnancy loss (22.0% vs. 32.7%), for a rate ratio of 0.67 (95% CI, 0.54 to 0.83; P<0.001), and of the ovarian hyperstimulation syndrome (1.3% vs. 7.1%), for a rate ratio of 0.19 (95% CI, 0.10 to 0.37; P<0.001), but a higher frequency of preeclampsia (4.4% vs. 1.4%), for a rate ratio of 3.12 (95% CI, 1.26 to 7.73; P=0.009). There were no significant between-group differences in rates of other pregnancy and neonatal complications. There were five neonatal deaths in the frozen-embryo group and none in the fresh-embryo group (P=0.06). CONCLUSIONS Among infertile women with the polycystic ovary syndrome, frozen-embryo transfer was associated with a higher rate of live birth, a lower risk of the ovarian hyperstimulation syndrome, and a higher risk of preeclampsia after the first transfer than was fresh-embryo transfer.

Abstract
The organs of eukaryotic organisms comprise complex interspersions of cell types, whose different molecular activities, and corresponding cellular states, cooperate during development to produce the final, functional organ. Dysfunction of organs in disease, particularly oncogenesis, initiates with changes of state of a minor subset of cells. It therefore is hard to detect early molecular indicators of disease within an overwhelming background of normal cells. Flow cytometry and sorting provides a convenient way to purify minority subpopulations, if a specific fluorophore can be unambiguously and exclusively associated with this subpopulation. We have generated a number of transgenic mouse lines expressing a nuclear-localized version of the Green Fluorescent Protein (GFP), within which the production of a chimeric histone 2B-GFP protein occurs under the control of a constitutively-active, actin-derived promoter, separated by a Floxed-STOP sequence. In the presence of Cre recombinase, within F1 progeny of these mouse lines, excision of the STOP sequence activates transcription which results in the emergence of cells containing green fluorescent nuclei. We describe the characterization of these lines using a combination of microscopic imaging, flow cytometry and sorting, and Reverse-Transcription polymerase chain reaction of transcripts within single sorted nuclei isolated from tissue homogenates. These lines should be particularly useful for analysis of transcriptional changes in oncogenesis. © 2016 International Society for Advancement of Cytometry.

Abstract
Genome-wide association studies (GWAS) have identified several common loci contributing to non-obstructive azoospermia (NOA). However, a substantial fraction of NOA heritability remains undefined, especially those low-frequency [defined here as having a minor allele frequency (MAF) between 0.5 and 5%] and rare (MAF below 0.5%) variants. Here, we performed a 3-stage exome-wide association study in Han Chinese men to evaluate the role of low-frequency or rare germline variants in NOA development. The discovery stage included 962 NOA cases and 1348 healthy male controls genotyped by exome chips and was followed by a 2-stage replication with an additional 2168 cases and 5248 controls. We identified three low-frequency variants located at 6p22.2 (rs2298090 in HIST1H1E encoding p.Lys152Arg: OR = 0.30, P = 2.40 × 10(-16)) and 6p21.33 (rs200847762 in FKBPL encoding p.Pro137Leu: OR = 0.11, P = 3.77 × 10(-16); rs11754464 in MSH5: OR = 1.78, P = 3.71 × 10(-7)) associated with NOA risk after Bonferroni correction. In summary, we report an instance of newly identified signals for NOA risk in genes previously undetected through GWAS on 6p22.2-6p21.33 in a Chinese population and highlight the role of low-frequency variants with a large effect in the process of spermatogenesis.

Abstract
The A2 harmonization team, a part of the Global Bioanalysis Consortium (GBC), focused on defining possible tiers of chromatographic-based bioanalytical method performance. The need for developing bioanalytical methods suitable for the intended use is not a new proposal and is already referenced in regulatory guidance language. However, the practical implementation of approaches that differ from the well-established full validation requirements has proven challenging. Advances in technologies, the need to progress drug development more efficiently, and emerging new drug compound classes support the use of categorized tiers of bioanalytical methods. This paper incorporated the input from an international team of experienced bioanalysts to surmise the advantages and the challenges of tiered approaches and to provide recommendations on paths forward.

Abstract
OBJECTIVE To investigate the effect of domestic urine-derived high-purity follicle- stimulating hormone (HP-FSH, Lishenbao) on the outcome of in vitro fertilization(IVF) embryo transfer (ET) in controlled ovarian stimulation (COS). METHODS From 1 September 2010 to 31 March 2011, total of 3178 infertility patients from 14 Reproductive Center with IVF or intracytoplasmic sperm injection (ICSI) indications who accepted first IVF or ICSI cycle were studied retrospectively. Their causes of infertility include all infertility factors except ovulatory dysfunction infertility and uterine factor infertility. The only long luteal phase gonadotropin-releasing hormone agonist (GnRH-a) protocol was included. Patients were divided into 2 groups according to the type of follicle-stimulating hormone (FSH) agents used: 1932 cases in HP-FSH group and 1246 cases in recombinant FSH (rFSH)group. Patients in both groups were combined with human menopausal gonadotropin (hMG) at doses of 150 U when follicle with diameter reached to 14-16 mm. When 3 dominate follicle with diameter reached 18 mm, hCG at dose of 5000 to 10 000 U or recombinant hCG at dose of 250 µg was administered by intramuscular injection. After 34 to 36 hours, oocytes were obtained guided by ultrasound, then IVF-ET were underwent in their Reproductive Center. The primary endpoint was comparison of live birth rate between the two groups. The secondary endpoints were comparisons of clinical pregnancy rate, miscarriage rate, and implantation rate, as well as COS and IVF outcome between the two groups. RESULTS (1) There were significantly differences in baseline characteristics of the patients between two groups. The mean age was elder(32 ± 4 versus 30 ± 4, P < 0.01) , the infertility duration was longer (5 ± 4 versus 5 ± 3, P < 0.01) , and antral follicle count (AFC) was less (11 ± 5 versus 13 ± 7, P < 0.01) in patients of HP-FSH group compared with those in patients of rFSH group. (2) As compared with rFSH, the total doses of gonadotropin needed was (2348 ± 1011) U in HP-FSH group versus (2022 ± 659) U in rFSH group, the number of oocytes 13 ± 6 in HP-FSH group and 14 ± 7 in rFSH group, the rate of embryo frozen cycle of 66.30% (1281/1932) in HP-FSH group and 74.88% (933/1246) in rFSH group, which all reached statistical difference (P < 0.01). However, there were no significant different implantation rate [30.49% (1111/3644) versus 32.45% (737/2271)] between two groups. The other clinical parameters did not show significant difference, including clinical pregnancy rate per started cycle [41.61% (804/1932) versus 41.97% (523/1246) ] , clinical pregnancy rate per ET cycle[46.58% (804/1726) versus 48.47% (523/1079)], live birth rate per started cycle[34.21% (661/1932) versus 34.19% (426/1246)], live birth rate per ET cycle [38.30% (661/1726) versus 39.48% (426/1079)], miscarriage rate[13.6% (109/804) versus 16.4% (86/523)], and moderate/severe ovarian hyperstimulation syndrome (OHSS) rate [5.80% (112/1932) versus 7.78% (97/1246)](P > 0.05).(3) Treatment cost: the cost of gonadotropins needed for the patients in HP-FSH group was lower than that in rFSH group (4005 ± 1650 versus 6482 ± 2095, P < 0.01). CONCLUSION In IVF/ICSI treatment cycles, domestic HP-FSH has similar live birth rate and lower financial burden when compared with rFSH.

Abstract
Objective To study the changes in T cell subsets and IL-7 in HIV-1-infected patients after seven years of highly active antiretroviral therapy (HAART). Methods Seventy-five individuals were included in this study (25 with effective HAART, 18 with ineffective HAART, 17 untreated HIV+ patients, and 15 volunteers in the HIV negative control group). The counts of CD4+, CD8+, CD8/CD38+, and CD8/HLADR+ T cells as well as the IL-7 protein expression was measured at 5 time points during a period of seven years in patients starting HAART (baseline) and in the HIV negative control group. The expression of CD127 on CD3+ T cells was measured by flow cytometry at a single time point (after 7 years) in patients with HAART and was compared with untreated HIV+ patients and the HIV negative control group. Results At baseline CD4+ T cell counts of HIV-1-infected patients were lower than that in the control group (p < 0.01), whereas the CD8+, CD8/HLADR+ and CD8/CD38+ T cell counts were higher than those in the control group (p <0.01). After seven years of effective HAART, the CD4+ T cell counts had increased and the CD8+ T cell count had decreased, although not to the normal levels (p < 0.05). Both the CD8/HLADR+ and CD8/CD38+ T cell counts had gradually approached those of the control group (p > 0.05). In the ineffective HAART group, the CD8/CD38+ T cell count had not decreased significantly, and CD8/HLADR+ T cell count gradually decreased. Before treatment, IL-7 serum levels of patients were significantly higher than that in the control group (p < 0.01). After seven years of effective HAART, IL-7 levels had gradually decreased, but were still higher than in the control group (p < 0.01). The CD127 expression on CD3+ CD8+ T cells in effective HAART patients was higher than in untreated HIV+ patients (p < 0.05), but was lower than that in the control group (p < 0.05). CD127 expression on CD3+ CD4+ T cells was not significantly different among the control group, untreated HIV+ patients and effective HAART group. Conclusion After seven years of effective HAART, the quantity and capacity of T cell subsets and IL-7 in HIV-1-infected patients had been partially restored, and the abnormal immune activation has significantly diminished.

Abstract
OBJECTIVE Glutamatergic dysregulation is implicated in the pathophysiology of fragile X syndrome (FXS). Riluzole is hypothesized to have an inhibitory effect on glutamate release, block excitotoxic effects of glutamate, and potentiate postsynaptic GABA(A) receptor function. Extracellular signal-related kinase (ERK) activation is known to be delayed in humans with FXS and knockout animal models of FXS. Correction of delayed ERK activation is a potential biomarker of treatment response in FXS. We conducted a six-week open-label prospective pilot study of riluzole (100 mg/day) in six adults with FXS. METHODS Riluzole was started at 50mg every evening and then increased to 50mg twice daily at week 2. The dose was kept constant for the final 4 weeks of the trial. Clinical response was determined by a score of 1 "very much improved" or 2 "much improved" on the Clinical Global Impressions Improvement (CGI-I) scale and a≥25% improvement on the Children's Yale-Brown Obsessive Compulsive Scale modified for Pervasive Developmental Disorders. The primary target of treatment in this study was repetitive, compulsive behavior that commonly occurs in persons with FXS. The study incorporated an ERK activation biomarker assay. Potential adverse effects were assessed in a systematic manner at all clinic visits and by phone between visits. RESULTS Riluzole treatment was associated with clinical response in 1 of 6 subjects (17%). Among a number of secondary outcome measures employed, significant improvement was only noted on the ADHD Rating Scale-IV (became non-significant when corrected for multiple comparisons). Riluzole use was associated with significant correction in ERK activation time in all subjects (mean change from 3.82±0.27 (baseline) to 2.99±0.26 (endpoint) minutes; p=0.007). Riluzole was well tolerated; mean increases in liver function tests occurred but drug discontinuation was not required. CONCLUSION Overall, riluzole use was not associated with significant clinical improvement despite uniform correction of peripheral ERK activation. Future directions of study include testing of riluzole in animal models of FXS and assessment of psychotropic monotherapy on ERK activation.

Abstract
Tumor protein D52 (also known as CRHSP-28) is highly expressed in multiple cancers and tumor-derived cell lines; however, it is normally abundant in secretory epithelia throughout the digestive system, where it has been implicated in Ca(2+)-dependent digestive enzyme secretion (41). Here we demonstrate, using site-specific mutations, that Ca(2+)-sensitive phosphorylation at serine 136 modulates the accumulation of D52 at the plasma membrane within 2 min of cell stimulation. When expressed in Chinese hamster ovary CHO-K1 cells, D52 colocalized with adaptor protein AP-3, Rab27A, vesicle-associated membrane protein VAMP7, and lysosomal-associated membrane protein LAMP1, all of which are present in lysosome-like secretory organelles. Overexpression of D52 resulted in a marked accumulation of LAMP1 on the plasma membrane that was further enhanced following elevation of cellular Ca(2+). Strikingly, mutation of serine 136 to alanine abolished the Ca(2+)-stimulated accumulation of LAMP1 at the plasma membrane whereas phosphomimetic mutants constitutively induced LAMP1 plasma membrane accumulation independent of elevated Ca(2+). Identical results were obtained for endogenous D52 in normal rat kidney and HeLA cells, where both LAMP1 and D52 rapidly accumulated on the plasma membrane in response to elevated cellular Ca(2+). Finally, D52 induced the uptake of LAMP1 antibodies from the cell surface in accordance with both the level of D52 expression and phosphorylation at serine 136 demonstrating that D52 altered the plasma membrane recycling of LAMP1-associated secretory vesicles. These findings implicate both D52 expression and Ca(2+)-dependent phosphorylation at serine 136 in lysosomal membrane trafficking to and from the plasma membrane providing a novel Ca(2+)-sensitive pathway modulating the lysosome-like secretory pathway.

Abstract
The heat shock protein 70 family members Hsc70 and Hsp70 are known to play a protective role against the onset of experimental pancreatitis, yet their molecular function in acini is unclear. Cysteine string protein (CSP-alpha) is a zymogen granule (ZG) membrane protein characterized by an NH(2)-terminal "J domain" and a central palmitoylated string of cysteine residues. The J domain functions as a cochaperone by modulating the activity of Hsc70/Hsp70 family members. A role for CSP-alpha in regulating digestive enzyme exocytosis from pancreas was investigated by introducing CSP-alpha truncations into isolated acini following their permeabilization with Perfringolysin O. Incubation of acini with CSP-alpha(1-82), containing the J domain, significantly augmented Ca(2+)-stimulated amylase secretion. Effects of CSP-alpha(1-82) were concentration dependent, with a maximum 80% increase occurring at 200 microg/ml of protein. Although CSP-alpha(1-82) had no effects on basal secretion measured in the presence of < or =10 nM free Ca(2+), it did significantly augment GTP-gammaS-induced secretion under basal Ca(2+) conditions by approximately 25%. Mutation of the J domain to abolish its cochaperone activity failed to augment Ca(2+)-stimulated secretion, implicating the CSP-alpha/Hsc70 cochaperone system as a regulatory component of the secretory pathway. CSP-alpha physically associates with vesicle-associated membrane protein 8 (VAMP 8) on ZGs, and the CSP-alpha-VAMP 8 interaction was dependent on amino acids 83-112 of CSP-alpha. Immunofluorescence analysis of acinar lobules or purified ZGs confirmed the CSP-alpha colocalization with VAMP 8. These data establish a role for CSP-alpha in regulating digestive enzyme secretion and suggest that CSP-alpha and Hsc70 modulate specific soluble N-ethylmaleimide-sensitive attachment receptor interactions necessary for exocytosis.

Abstract
Lack of production of the Fragile X Mental Retardation Protein (FMRP) leads to changes in dendritic morphology and resultant cognitive and behavioral manifestations characteristic of individuals with Fragile X syndrome (FXS). FMRP is an RNA-binding protein that is believed to regulate the translation of a large number (probably over 100) of other proteins, leading to a complex and variable set of symptoms in FXS. In a mouse model of FXS, we previously observed delayed initiation of synaptically localized protein synthesis in response to neurotransmitter stimulation, as compared to wild-type mice. We now likewise have observed delayed early-phase phosphorylation of extracellular-signal regulated kinase (ERK), a nodal point for cell signaling cascades, in both neurons and thymocytes of fmr-1 KO mice. We further report that early-phase kinetics of ERK activation in lymphocytes from human peripheral blood is delayed in a cohort of individuals with FXS, relative to normlal controls, suggesting a potential biomarker to measure metabolic status of disease for individuals with FXS.

Abstract
Sequence searching is one of major operations in modern bioengineering. Recent emerging multicore provides a promising technology to enhance sequence searching performance. However, efficiently employing the multicore for a uniprocessor-oriented algorithm is a difficult task. This paper presents a methodology to profile processing requirements for DNA sequence search algorithms, parallelise them onto multicore, and analytically evaluate their performance. The key feature of this methodology is that entire processes are automated and it requires users little understanding of the complexity of algorithms and multicore hardware architecture. Our methodology considers three approaches to parallelise searching operations: queries, database, and task segmentation.

Abstract
The interleukin (IL)-1 family members IL-1α, -1β, and -18 are potent inflammatory cytokines whose activities are dependent on heterodimeric receptors of the IL-1R superfamily, and which are regulated by soluble antagonists. Recently, several new IL-1 family members have been identified. To determine the role of one of these family members in the skin, transgenic mice expressing IL1F6 in basal keratinocytes were generated. IL1F6 transgenic mice exhibit skin abnormalities that are dependent on IL-1Rrp2 and IL-1RAcP, which are two members of the IL-1R family. The skin phenotype is characterized by acanthosis, hyperkeratosis, the presence of a mixed inflammatory cell infiltrate, and increased cytokine and chemokine expression. Strikingly, the combination of the IL-1F6 transgene with an IL1F5 deficiency results in exacerbation of the skin phenotype, demonstrating that IL-1F5 has antagonistic activity in vivo. Skin from IL1F6 transgenic, IL1F5−/− pups contains intracorneal and intraepithelial pustules, nucleated corneocytes, and dilated superficial dermal blood vessels. Additionally, expression of IL1RL2, -1F5, and -1F6 is increased in human psoriatic skin. In summary, dysregulated expression of novel agonistic and antagonistic IL-1 family member ligands can promote cutaneous inflammation, revealing potential novel targets for the treatment of inflammatory skin disorders.

Abstract
Previous studies have demonstrated roles for vesicle-associated membrane protein 2 (VAMP 2) and VAMP 8 in Ca(2+)-regulated pancreatic acinar cell secretion, however, their coordinated function in the secretory pathway has not been addressed. Here we provide evidence using immunofluorescence microscopy, cell fractionation, and SNARE protein interaction studies that acinar cells contain two distinct populations of zymogen granules (ZGs) expressing either VAMP 2 or VAMP 8. Further, VAMP 8-positive granules also contain the synaptosome-associated protein 29, whereas VAMP 2-expressing granules do not. Analysis of acinar secretion by Texas red-dextran labeling indicated that VAMP 2-positive ZGs mediate the majority of exocytotic events during constitutive secretion and also participate in Ca(2+)-regulated exocytosis, whereas VAMP 8-positive ZGs are more largely involved in Ca(2+)-stimulated secretion. Previously undefined functional roles for VAMP and syntaxin isoforms in acinar secretion were established by introducing truncated constructs of these proteins into permeabilized acini. VAMP 2 and VAMP 8 constructs each attenuated Ca(2+)-stimulated exocytosis by 50%, whereas the neuronal VAMP 1 had no effects. In comparison, the plasma membrane SNAREs syntaxin 2 and syntaxin 4 each inhibited basal exocytosis, but only syntaxin 4 significantly inhibited Ca(2+)-stimulated secretion. Syntaxin 3, which is expressed on ZGs, had no effects. Collectively, these data demonstrate that individual acinar cells express VAMP 2- and VAMP 8-specific populations of ZGs that orchestrate the constitutive and Ca(2+)-regulated secretory pathways.

Abstract
BACKGROUND Recent observational studies suggest that preformed vitamin A (VA) intakes of 1500-2000 microg/d may increase the risk of osteoporosis and hip fracture. However, few studies have examined associations between biologic indicators of VA and osteoporosis. OBJECTIVE This study characterized VA intake, serum VA, and bone turnover markers in postmenopausal women with and without osteoporosis. DESIGN Bone density was measured by dual-energy X-ray absorptiometry. Subjects were separated into those with osteoporosis (n = 30) and those with normal bone density (n = 29). Women with osteopenia were excluded. Complete blood chemistries were obtained. Serum was analyzed for retinol, retinyl esters, and metabolites. Assays for 3 bone turnover markers were performed by using commercially available kits. Diet records were quantified. Logistic regression was used to test for an association between dietary and serum variables and osteoporosis. RESULTS Dietary VA did not differ significantly between the groups but was nearly twice the Recommended Dietary Allowance in both groups. Body mass index (BMI) and serum triacylglycerols were significantly lower in the osteoporosis group. Retinyl esters were not elevated in either group, but a trend existed for the association of serum retinyl esters as a percentage of total VA with osteoporosis (P = 0.070) after adjustment for BMI and triacylglycerols in the statistical model. Milk, fruit, and vegetable intakes were below the current recommendations. CONCLUSIONS Serum retinyl esters were not elevated in these postmenopausal women despite intakes of total VA that were nearly two-fold the Recommended Dietary Allowance. However, retinyl ester concentration (percentage of total VA) was marginally associated with osteoporosis and should be further investigated.

Abstract
Ca(2+)-regulated heat-stable protein (CRHSP-28) is a member of the TPD52 protein family that has been shown to regulate Ca(2+)-dependent secretory activity in pancreatic acinar cells. Immunofluorescence microscopy of isolated lobules demonstrated that CRHSP-28 is localized to a supranuclear apical compartment in acini and accumulates immediately below the apical membrane within 2 min of CCK octapeptide (CCK-8) stimulation. Dual-immunofluorescence microscopy demonstrated an endosomal localization of CRHSP-28 that strongly overlapped with early endosomal antigen-1 (EEA-1) on vesicular structures throughout the apical cytoplasm but showed only minimal overlap with the transferrin receptor, which is present in basolaterally derived endosomes. Significant overlapping of CRHSP-28 with the trans-Golgi network marker-38 was also noted in supranuclear regions of acini. Interestingly, treatment of lobules with brefeldin A reversibly disrupted the vesicular localization of CRHSP-28 and EEA-1 within the apical cytoplasm. The CCK-8-induced accumulation of CRHSP-28 in subapical regions of acini was not altered by inhibition of apical endocytosis with the actin filament-disrupting agent latrunculin B. Immunoelectron microscopy confirmed that CRHSP-28 is associated with the limiting membrane of irregularly shaped vesicular structures of low electron density in the apical cytoplasm that are positive for EEA-1 staining. Sparse, but significant, CRHSP-28 immunoreactivity was also observed along the limiting membrane of zymogen granules. Consistent with immunofluorescence data, CRHSP-28 was found to accumulate in clusters on endosomes and positioned between zymogen granules below the cell apex on CCK-8 stimulation. These data indicate that CRHSP-28 is present within endocytic and exocytic compartments of acinar cells and is acutely regulated by secretagogue stimulation.

Abstract
Five different colored carrots were analyzed for their carotenoid profile and underwent sensory evaluation to determine consumer acceptance (n = 96). Four major carotenoids were identified and quantified by use of HPLC methods. High beta-carotene orange carrots were found to contain the greatest concentration of total carotenoids. Except for the white, all the carrots are a significant source of bioavailable carotenoids. Sensory evaluation showed the high beta-carotene orange and white carrots to be favored over the yellow, red, and purple carrots in both blind and nonblind treatments (P < 0.01). However, all the carrots were well accepted by the consumer panel. With this information, carrot growers should be encouraged to cultivate specialty carrots to provide sources of both vitamin A precursors and phytochemicals.

Abstract
OBJECTIVE To make a comparatively analysis of the effects of 10% KCl injection into the fatal cardiac area and yolk-sac aspiration on multifetal pregnancy reduction. METHODS Twenty-three patients with multifetus were selected in the investigation. Eight of the patients accepted 10% KCl injection into the fatal cardiac area, and 15 of them received yolk-sac aspiration. The average number of punctures, average time of reduction operation, failure rate of operation, abortion rate, and infection rate were observed. RESULTS The average time of reduction operation[(2.8 +/- 0.7) min] of aspiration was significantly lower than that of 10% KCl injection [(5.11 +/- 1.35) min] (P < 0.05). The infection rate of yolk-sac aspiration was 6.7%, lower than that of 10% KCl injection (37.5%) (P > 0.05). Cardic area injection showed a higher infection rate, and no significant difference was observed in the average number of punctures, failure rate of operation and abortion rate(P > 0.05). CONCLUSION Although both yolk-sac aspiration and cardiac area injection were safe and reliable methods for multifetal pregnancy reduction, the former is worth recommending for its shorter operation time heeded and lower infection rate, especially for the multifetal patients within 60 gestation days.

Abstract
Ca(2+)-regulated heat-stable protein of 28 kDa (CRHSP-28; a member of the tumor protein D52 family) is highly expressed in exocrine glands and was shown to regulate digestive enzyme secretion from pancreatic acinar cells. We found CRHSP-28 highly expressed in cultured mucosal secretory T84 cells, consistent with an important regulatory role in apical membrane trafficking. Stimulation of cells with carbachol (CCh) induced rapid, concentration-dependent phosphorylation of CRHSP-28 on at least two serine residues. Isoelectric focusing and immunoblotting were used to characterize cellular mechanisms governing CRHSP-28 phosphorylation. Phosphorylation depends on elevated cellular Ca2+, being maximally induced by ionomycin and thapsigargin and fully inhibited by BAPTAAM. In vitro phosphorylation of recombinant CRHSP-28 was 10-fold greater by casein kinase II (CKII) than Ca2+/calmodulin-dependent protein kinase II (CaMKII). However, phosphopeptide mapping studies demonstrated that CaMKII induced an identical phosphopeptide profile to endogenous CRHSP-28 immunoprecipitated from T84 cells. Although calmodulin antagonists had no effect on CCh-stimulated phosphorylation, disruption of actin filaments by cytochalasin D inhibited phosphorylation by 50%. Confocal microscopy indicated that CRHSP-28 is expressed in perinuclear regions of cells and accumulates immediately below the apical membrane of polarized monolayers following CCh stimulation. CaMKII was also localized to the subapical cytoplasm and was clearly displaced following actin filament disruption. These data suggest that CRHSP-28 phosphorylation is regulated by a CaMKII-like enzyme and likely involves a translocation of the protein within the apical cytoplasm of epithelial cells.
