Abstract
BACKGROUND Understanding how analgesics are used in different countries can inform initiatives to improve the pharmacological management of pain in nursing homes. AIMS To compare patterns of analgesic use among Australian and Japanese nursing home residents; and explore Australian and Japanese healthcare professionals' perspectives on analgesic use. METHODS Part one involved a cross-sectional comparison among residents from 12 nursing homes in South Australia (N = 550) in 2019 and four nursing homes in Tokyo (N = 333) in 2020. Part two involved three focus groups with Australian and Japanese healthcare professionals (N = 16) in 2023. Qualitative data were deductively content analysed using the World Health Organization six-step Guide to Good Prescribing. RESULTS Australian and Japanese residents were similar in age (median: 89 vs 87) and sex (female: 73% vs 73%). Overall, 74% of Australian and 11% of Japanese residents used regular oral acetaminophen, non-steroidal anti-inflammatory drugs or opioids. Australian and Japanese healthcare professionals described individualising pain management and the first-line use of acetaminophen. Australian participants described their therapeutic goal was to alleviate pain and reported analgesics were often prescribed on a regular basis. Japanese participants described their therapeutic goal was to minimise impacts of pain on daily activities and reported analgesics were often prescribed for short-term durations, corresponding to episodes of pain. Japanese participants described regulations that limit opioid use for non-cancer pain in nursing homes. CONCLUSION Analgesic use is more prevalent in Australian than Japanese nursing homes. Differences in therapeutic goals, culture, analgesic regulations and treatment durations may contribute to this apparent difference.

Abstract
Patient-derived xenograft (PDX) models retain the characteristics of tumors and are useful tools for personalized therapy and translational research. In this study, we aimed to establish PDX models for uterine corpus malignancies (UC-PDX) and analyze their similarities. Tissue fragments obtained from 92 patients with uterine corpus malignancies were transplanted subcutaneously into immunodeficient mice. Histological and immunohistochemical analyses were performed to compare tumors of patients with PDX tumors. DNA and RNA sequencing were performed to validate the genetic profile. Furthermore, the RNA in extracellular vesicles (EVs) extracted from primary and PDX tumors was analyzed. Among the 92 cases, 52 UC-PDX models were established, with a success rate of 56.5%. The success rate depended on tumor histology and staging. The pathological and immunohistochemical features of primary and PDX tumors were similar. DNA sequencing revealed similarities in gene mutations between the primary and PDX tumors. RNA sequencing showed similarities in gene expressions between primary and PDX tumors. Furthermore, the RNA profiles of the EVs obtained from primary and PDX tumors were similar. As UC-PDX retained the pathological and immunohistochemical features and gene profiles of primary tumors, they may provide a platform for developing personalized medicine and translational research.

Abstract
BACKGROUND Congenital heart disease occurs in approximately 1 in 100 cases. Although sibling occurrence is high (3-9%), the causative genes for this disease are still being elucidated. PLD1 (Phospholipase D1) is a recently discovered gene; however, few case reports have been published on it. In this report, we describe a case of triplicate fetal congenital heart disease that was diagnosed as a PDL1 mutation. Our objective is to explore the clinical manifestations of PLD1 mutations in this particular case. CASE PRESENTATION A 32-year-old Japanese woman (gravida, para 0) was introduced since fetus four chamber view was not clear and was diagnosed with ductus arteriosus-dependent left ventricular single ventricle and pulmonary atresia at 21 weeks and 1 day of gestation during her first pregnancy. Artificial abortion using Gemeprost was performed at 21 weeks and 5 days of gestation. The second pregnancy was diagnosed as pulmonary atresia with intact ventricular septum with cardiomegaly, a cardiothoracic area ratio of more than 35%, and a circulatory shunt at 13 weeks and 3 days of gestation. Subsequently, intrauterine fetal death was confirmed at 14 weeks and 3 days of gestation. Regarding the third pregnancy, fetal ultrasonography at 11 weeks and 5 days of gestation showed mild fetal hydrops and moderate tricuspid valve regurgitation. At 16 weeks and 5 days of gestation, the fetus was suspected to have a left ventricular-type single ventricle, trace right ventricle, pulmonary atresia with intact ventricular septum, or cardiomyopathy. Cardiac function gradually declined at 26 weeks of gestation, and intrauterine fetal death was confirmed at 27 weeks and 5 days of gestation. The fourth pregnancy resulted in a normal heart with good progression and no abnormal baby. We submitted the first and second fetuses' umbilical cord, third fetus' placenta, and the fourth fetus' blood to genetic testing using whole exome analysis with next generation sequencing. Genetic analysis identified hemizygous PLD1 mutations in the first, second, and third fetuses. The fourth fetus was heterozygous. In addition, the parents were heterozygous for PLD1. This case is based on three consecutive cases of homozygosity for the PLD1 gene in the sibling cases and the fetuses with recurrent right ventricular valve dysplasia. This will elucidate the cause of recurrent congenital heart disease and intrauterine fetal death and may serve as an indicator for screening the next fetus. To date, homozygous mutations in PLD1 that repeat three times in a row are not reported, only up to two times. The novelty of this report is that it was repeated three times, followed by a heterozygous live birth. CONCLUSIONS This report is consistent with previous reports that mutations in PLD1 cause right ventricular valve dysplasia. However, there have been few case reports of PLD1 mutations, and we hope that this report will contribute to elucidate the causes of congenital heart disease, especially right ventricular valve dysplasia, and that the accumulation of such information will provide more detailed information on PLD1 mutations in heart disease.

Abstract
Sentinel node biopsy (SNB) is performed worldwide in patients with endometrial cancer (EC). The aim of this study was to evaluate and compare the occurrence rate of lymphatic complications between SNB and pelvic lymphadenectomy (LND) for EC. The medical records of women who underwent SNB or pelvic LND for EC between September 2012 and April 2022 were assessed. A total of 388 patients were enrolled in the current study. Among them, 201 patients underwent SNB and 187 patients underwent pelvic LND. The occurrence rates of lower-extremity lymphedema (LEL) and pelvic lymphocele (PL) were compared between the patients who underwent SNB and those who underwent pelvic LND. The SNB group had a significantly lower occurrence rate of lower-extremity LEL than the pelvic LND group (2.0% vs. 21.3%, p < 0.01). There were no patients who had PL in the SNB group; however, 4 (2.1%) patients in the pelvic LND group had PL. The occurrence rates of lower-extremity LEL and PL were significantly lower in patients who underwent SNB than those who underwent pelvic LND. SNB for EC has a lower risk of lymphatic complications compared to systemic LND.

Abstract
Older adults often receive polypharmacy, including some medications for chronic diseases. Nutritional management after admission to a nursing home may enable to deprescribe some chronic disease medications. This study aimed to investigate the status of deprescribing of chronic disease medications among nursing home residents, and to assess the appropriateness based on changes of laboratory test values and nutritional status. A multi-center prospective cohort study was conducted in 6 Geriatric Health Services Facilities, a major type of nursing homes in Japan. Newly admitted residents aged ≥ 65 years who took ≥1 medication for hypertension, diabetes, or dyslipidemia at admission were recruited. Participants who stayed for 3 months were included in the analysis. Medications at admission and 3 months after admission and situations for deprescribing were investigated. Changes in body mass index, blood pressure, laboratory tests (e.g., cholesterol and hemoglobin A1c levels), energy intake, and International Classification of Functioning, Disability and Health staging were evaluated. Sixty-nine participants (68% female, 62% aged ≥ 85 years) were included. At admission, 60 participants had medications for hypertension, 29 for dyslipidemia, and 13 for diabetes. Those receiving lipid-modifying drugs (mainly statins) decreased from 29 to 21 (72%; P = .008), since their cholesterol levels was within the normal range or was low at admission, and they had no history of cardiovascular events. However, there were no statistically significant changes in the frequencies of antihypertensive drugs (60 to 55; 92%; P = .063) or antidiabetic drugs (13 to 12; 92%; P = 1.000). During the 3-month observation, body mass index and diastolic blood pressure decreased, while energy intake and serum albumin level increased. Nutritional management after admission to a ROKEN may facilitate appropriate deprescribing of lipid-modifying drugs, by offseting the effects of discontinuation of these drugs.

Abstract
OBJECTIVES To evaluate the prescription and discontinuation of psychotropic drugs (PD) and drugs with anticholinergic properties (DAP) in residents with dementia admitted to Roken, a major type of long-term care facility in Japan. DESIGN Cohort study. SETTING A nationwide questionnaire survey across 3598 Roken in Japan in 2015 (up to five randomly selected residents per facility). PARTICIPANTS This study included 1201 residents from 343 Roken (response rate: 10%). We determined the presence and severity of dementia using a nationally standardised measure. PRIMARY AND SECONDARY OUTCOME MEASURES Prescriptions of PD and DAP at admission and 2 months after admission were evaluated. Multivariable logistic regression was used to evaluate the associations of residents' baseline characteristics with prescriptions or discontinuation. RESULTS Prescription rates decreased for antidementia drugs (19.4% to 13.0%), hypnotics (25.1% to 22.6%) and anxiolytics (12.3% to 10.7%), whereas those for other PD, such as antipsychotics (13.2% to 13.6%), antidepressants (7.4% to 6.7%), antiepileptic drugs (7.1% to 7.8%) and DAP (35.2% to 36.6%) did not statistically significantly decrease. Some factors were associated with the prescriptions, for example, for antipsychotics, older age (≥85 years) (adjusted OR (aOR), 0.60; 95% CI 0.43 to 0.85) and being bedridden (aOR 0.67; 95% CI 0.47 to 0.97) were associated with a lower use of antipsychotics, whereas severe dementia was associated with a higher use of antipsychotics (aOR 3.26; 95% CI 2.26 to 4.70). At an individual level, a quarter of residents prescribed PD or DAP at admission had discontinued at least one PD or DAP, respectively, 2 months after admission. Antidementia drug use in severe dementia (aOR 1.86; 95% CI 1.04 to 3.31) and PD use in older age (aOR 1.61; 95% CI 1.00 to 2.60; in residents with disabling dementia) were associated with discontinuation. CONCLUSIONS There is possible scope for deprescribing PD and DAP in Roken residents with dementia to mitigate the risks of adverse events.

Abstract
[Purpose] It has been reported that exercise affects skeletal muscle in the chronic obstructive pulmonary disease (COPD) disease model. In this study, we examined the effects of neuromuscular electrical stimulation (NMES) in skeletal muscle on alveoli and cytokines. [Materials and Methods] We used twenty wild-type mice, randomly divided into three groups: Group A: Control (non-COPD, non-amyotrophia, non-NMES), Group B: COPD, amyotrophia with NMES and Group C: COPD, amyotrophia without NMES. Among those, a group of mice with ages from 12 to 14 weeks were used to create a chronic obstructive pulmonary disease (COPD) model, a group of mice with ages from 15 to 16 weeks was used to create a disuse syndrome by hind limb suspension, and a group of mice with ages from 17 to 28 weeks (12 weeks) were used to implement NMES. In this study, we used the real-time PCR method to assess the mRNA expression levels. We also conducted morphological analysis, assessed macrophage expression level by staining (general staining and immunostaining), and employed spirometry. [Results] Our study results showed significant decreases in Interleukin-6 (IL-6) levels in the lungs and muscle RING-finger protein-1 (MuRF1) in the muscles. Moreover, the pulmonary stromal macrophage marker (F4/80) and the protease marker (MMP12) showed significantly decreased expression, while no change was observed in the morphological of the alveolar spaces (mean linear intercept). [Conclusion] On the basis of these findings, our study reveals that NMES affects cytokines and macrophages in COPD skeletal muscle atrophy.

Abstract
The number of heart failure patients is increasing rapidly in Japan because of its large elderly population. As age increases, arterial stiffness and physical dysfunction progress. This study aimed to evaluate the association between the physical function and arterial stiffness in elderly heart failure patients.This retrospective, observational study includes data from 100 heart failure patients aged ≥ 65 years who were admitted to our hospital and underwent cardiac rehabilitation. The Cardio-Ankle Vascular Index (CAVI) was measured as an indicator of arterial stiffness. Body composition was assessed by bioelectrical impedance analysis. To determine the degree of physical function, we assessed handgrip strength, five-meter walk speed (5MWS), five-repetition sit-to-stand time (5RSST) and six-minute walk distance (6MWD). Sarcopenia was defined using Asian guidelines based on physical function and body composition.Among 100 patients, 47.0% of patients had sarcopenia. After adjustments for age, sex, atrial fibrillation, and ischemic cardiomyopathy, CAVI was significantly higher in with sarcopenia patients than those without sarcopenia. Age, handgrip strength, 5MWS, 5RSST, and 6MWD were associated with CAVI, and 6MWD was as an independent determinant factor of CAVI.6MWD was recognized as an accurate physical function indicator. These findings suggested that physical function and arterial stiffness complement each other. To restore cardiac dysfunction, improving both arterial stiffness and physical function might be useful.

Abstract
OBJECTIVES No established approaches exist for the pharmacological management of cardiovascular diseases (CVDs) in residents of long-term care facilities (LTCFs). This study aimed to evaluate the use of drugs for CVD prevention and treatment (CVD-related drugs) in a major type of LTCF in Japan. METHODS This study included 1318 randomly selected residents at 349 intermediate care facilities for older adults (called Roken). Prescriptions were investigated at admission and two months after admission according to therapeutic categories. Logistic regression was used to identify residents' characteristics that were associated with prescriptions of CVD-related drugs. RESULTS Prescriptions of all types of drugs and CVD-related drugs decreased in 36 % and 16 % of residents, respectively. Half of the residents received antihypertensives, a quarter received antiplatelets and diuretics, whereas one-tenth received antidiabetics, oral anticoagulants, and lipid-modifying drugs. The prevalence of most of individual drug categories were similar among residents with different physical or cognitive function, except for fewer antihypertensive and lipid-modifying drugs in those with severe cognitive disability. Adjusted analyses for prescriptions at two months after admission revealed that bedridden residents were more likely to be prescribed diuretics but less likely to be prescribed antihypertensives, antiplatelets, or lipid-modifying drugs. Residents with severe cognitive disability were less likely to be prescribed antihypertensives or lipid-modifying drugs. A known history of cardiovascular events was associated with greater use of CVD-related drugs. CONCLUSION CVD-related drugs were commonly prescribed for Roken residents, including those with low physical and cognitive functions. Deprescribing may contribute to the optimization of pharmacotherapy in LTCF residents.

Abstract
e17041 Background: G protein-coupled receptor 30 (GPR30) is a 7-transmembrane estrogen receptor that functions alongside traditional estrogen receptors to regulate the cellular responses to estrogen. Recent studies suggest that the high expression of GPR30 is associated with a poor prognosis in breast cancer or endometrial cancer. Although the role of GPR30 in ovarian cancer was unclear, we revealed that GPR30 is associated with poor prognosis in ovarian cancer. On the other hand, Epithelial-to-Mesenchymal Transition (EMT) is involved in cancer metastasis. The purpose of this study is to reveal how GPR30 was associated with poor prognosis and whether associated with EMT in ovarian cancer. Methods: We examined whether GPR30 signaling activates the EGFR-Akt pathway in an ovarian cancer cell line (Caov-3) by a Western blotting analysis. We also examined the effect of GPR30 on EMT were evaluated in Caov-3, which were cultured both in two-dimensional (2D) culture and three-dimensional (3D) culture model. GPR30 agonist, G1, was used to confirm the regulatory effects of GPR30 on the change of phenotypic modulation and EMT markers expression. Results: The phosphorylation of the EGFR and Akt could be significantly enhanced by G1 (p < 0.05) and inhibited by a Src family kinase inhibitor. In 3D culture, the stimulation of GPR30 leads the floating and sphere formation in Caov-3. G1-induced EMT was observed with related regulation of EMT markers expression at both mRNA and protein level. G1 induced the decrease of E-cadherin level and the increase of Snail and Vimentin in RT-PCR and Western blotting. Knockdown of GPR30, using siRNA, blocked G1-induced EMT. Conclusions: GPR30 increases the phosphorylation of Akt via the EGFR in ovarian cancer cells and changes ovarian cancer cells to the EMT state.GPR30 might be an important molecule related to metastasis process in ovarian cancer.

Abstract
Background It is well known that ovarian mature cystic teratomas (MCTs) occasionally go through malignant transformations. Among these, approximately 75% of histological types are squamous cell carcinoma, with the other types being exceptionally rare. We report an extremely rare case of ovarian clear cell carcinoma arising from ovarian mature cystic teratoma. Case presentation The case was a 71-year-old woman with abdominal distention. Ultrasonography and magnetic resonance imaging showed a huge mass in her abdominal cavity. Fluorodeoxyglucose-positron emission tomography (FDG-PET) showed FDG uptake not only in the pelvic tumor but also in the hepatic nodule, thus suggesting metastases. We performed a total abdominal hysterectomy, bilateral salpingo-oophorectomy, and an omentectomy. The pathological diagnosis showed clear cell carcinoma of the right ovary which arose from the MCT with malignant transformation pT2aNXM1. Although the patient underwent chemotherapy, she died after 17 months. Conclusion This case is histologically characteristic of the proof of transition from simple squamous epithelium via simple glandular epithelium to papillary change with atypia. This is the first case report of unaccompanied clear cell carcinoma arising from MCT reported in English literatures.

Abstract
We performed a comprehensive quantification of 20 amino acids in RPMI 1640 medium-cultured human colorectal adenocarcinoma cells to evaluate the efficacy of 5-fluorouracil treatment under hypoxic and hypoglycemic conditions, which mimic the tumor microenvironment. In this study, we developed a simple and comprehensive analytical method by using LC-MS/MS connected to the Intrada amino acid column, which eluted amino acids within 9 min. The present method covered a linearity range of 3.6 - 1818 μM, except for Gly (227 - 1818 μM), Ala, Asp, His (7.1 - 1818 μM each), and Trp (3.6 - 909 μM). The limits of detection were in the range of 0.02 - 38.0 pmol per injection in a standard solution. Amino acid concentration data were analyzed using principal-component analysis to represent samples on two-dimensional graphs. Linear discriminant analysis was used to classify samples on the score plots. Using this approach, the effect of 5-fluorouracil treatment could be successfully discriminated at high discrimination rates. Moreover, several amino acids were extracted from corresponding loading plots as candidate markers for distinguishing the effects of the 5-fluorouracil treatment or tumor microenvironmental conditions. These results suggest that our proposed method might be a useful tool for evaluating the efficacy of anticancer drugs in the tumor microenvironment.

Abstract
The aim of this study was to evaluate the dissemination of cancer cells at laparoscopic hysterectomy according to the intraperitoneal cytology.Patients with endometrial cancer underwent total laparoscopic modified radical hysterectomy. Peritoneal wash cytology was performed on entering the peritoneal cavity before surgical preparation and just after hysterectomy.Seventy-eight patients underwent laparoscopic hysterectomy for endometrial cancer. Among the 15 patients who had positive intraperitoneal cytology on entering the peritoneal cavity, 10 converted to negative intraperitoneal cytology after hysterectomy. In contrast, among the 63 patients who had negative intraperitoneal cytology on entering the peritoneal cavity, 2 converted to positive intraperitoneal cytology after hysterectomy.While surgery can reduce the number of cancer cells in the peritoneal cavity, leakage can occur, as seen in some cases of hysterectomy. Careful washing must be performed after hysterectomy.

Abstract
[Purpose] Hormone replacement therapy has been reported to be effective for alleviating
menopausal symptoms, its side effects have been a concern. Therefore, it is necessary to
investigate methods that could alleviate menopausal symptoms but with fewer side effects.
Few previous reports have investigated the effects of simplified, viable manual lymph
drainage, particularly the effects of one-time therapy on physiologically active
substances and other variables. Effects of one-time simplified lymph drainage performed at
salon A were investigated in females with any type of menopausal symptoms, such as edema
or a sense of fatigue. [Subjects and Methods] Before and after lymph drainage, saliva was
collected to detect substances that would reveal immune function. Questionnaire surveys
were also conducted before and after therapy. [Results] Cortisol and
dehydroepiandrosterone levels were significantly reduced after therapy compared with those
before therapy. The questionnaire survey showed a significant decrease in the visual
analog scale. Also apparent were positive opinions, such as “I feel better” and “My legs
feel lighter.” [Conclusion] These results demonstrated the stress reduction effect of
one-time simplified lymph drainage, which decreased cortisol and dehydroepiandrosterone
levels. This therapy was also shown to produce positive mental and physical effects.

Abstract
Metabolomic studies conducted for evaluating cancer pathogenesis and progression by monitoring the amino acids metabolic balance hold great promise for assessing current and future anticancer treatments. We performed a comprehensive quantification of 21 amino acids concentrations in cultured human colorectal adenocarcinoma cells treated with the anticancer drugs 5-fluorouracil, irinotecan, and cisplatin. A precolumn fluorescence derivatization-HPLC method involving 6-aminoquinolyl-N-hydroxysuccinimidyl carbamate was used. Amino acid concentration data were analyzed by principal-component analysis and partial least-squares multivariate statistical methods to represent samples on two-dimensional graphs. The hierarchical cluster analysis and linear discriminant analysis were used to classify the samples on the score plots. Unlike the cluster analysis approach, the linear discrimination analysis classification successfully distinguished anticancer drug-treated samples from the untreated controls. Moreover, three candidate amino acids (serine, aspartic acid, and methionine) were identified from the loading plots as potential biomarkers. Our proposed method might be able to evaluate the effectiveness of anticancer therapy even in small laboratories or medical institutions.

Abstract
[Purpose] This study examined how exercise capacity and the
oxidative stress regulation system are affected by different amounts of dietary Ubiquinol
(reduced form of coenzyme Q10, H2CoQ10: QH) over the long term. [Subjects and
Methods] Twenty-three senescence-accelerated mouse P1 (SAMP1) mice were randomly divided
into two groups: one consuming a relatively high amount of QH (300 mg/kg; Group A) and the
other a relatively low amount (30 mg/kg, Group B). Food and tap water were provided ad
libitum. Both groups were made to run on a treadmill until exhaustion, and total running
duration was measured. For the oxidative stress regulation system, the d-ROM test value
(degree of oxidative stress) and BAP test value (antioxidant potential) were measured in a
resting state, and then the BAP/d-ROM ratio (B/R ratio) was calculated. The values of
plasma QH and plasma ubiquinone (plasma oxidized form of CoQ10) were also measured, and
the reduced ratio was calculated. Measurements were taken 3 times: at the start of the
study when the animals were 39 weeks old (baseline), after consumption of QH for 7 months
(7 mo), and after consumption of QH for 10 months (10 mo). [Results] The senescence score
at 10 mo was significantly lower in Group A. Comparison of the mean percentage change in
running time showed a difference of 15.1% between the 2 groups. At 10 mo, the d-ROM test
value was significantly increased and the B/R ratio was significantly decreased in Group
B. Significant increases in the plasma QH value and reduced ratio were seen in Group A.
[Conclusion] Group A showed a greater decrease in the d-ROM test and increase in the
reduced ratio than Group B. Thus, a dose-dependent effect of QH consumption was
demonstrated.

Abstract
[Purpose] In this study, combined training with breathing resistance and sustained
physical exertion was carried out to evaluate its physiological effects and its effect on
improve endurance capacity. [Subjects and Methods] The subjects were nine healthy adults
(mean age 20.4, SD ± 1.7 years). The combined training group (n = 5) carried out 6 weeks
of combined training using a cycle ergometer, with exercise load tests and respiratory
function tests performed before and after the training. The results of the training were
compared to a control group (n = 4) that only performed the cycling exercise without the
combined training with breathing resistance. [Results] In the combined training group,
ventilatory threshold, maximal load of the cycle ergometer in exercise load tests, and
maximal voluntary ventilation increased after training. These increases after training
were all significant, but none of these variables changed significantly in the control
group. [Conclusion] The results imply that in comparison to conventional training methods,
combined training with breathing resistance and sustained physical exertion is beneficial
for increasing endurance capacity and respiratory muscle function. This result provides
important information regarding the effects of the new training method for improving
endurance capacity.

Abstract
5'-AMP-activated protein kinase (AMPK) and its pharmacological modulators have been targeted for treating type 2 diabetes. Extracellular uridine 5'-diphosphate (UDP) activates P2Y6 receptors (P2Y6Rs) in pancreatic β-cells to release insulin and reduce apoptosis, which would benefit diabetes. Here, we studied the role of P2Y6R in activation of AMPK in MIN6 mouse pancreatic β-cells and insulin secretion. Treatment with a potent P2Y6R dinucleotide agonist MRS2957 (500nM) activated AMPK, which was blocked by P2Y6R-selective antagonist MRS2578. Also, MRS2957 induced phosphorylation of acetyl-coenzyme A carboxylase (ACC), a marker of AMPK activity. Calcium chelator BAPTA-AM, calmodulin-dependent protein kinase kinase (CaMKK) inhibitor STO-069 and IP3 receptor antagonist 2-APB attenuated P2Y6R-mediated AMPK phosphorylation revealing involvement of intracellular Ca(2+) pathways. P2Y6R agonist induced insulin secretion at high glucose, which was reduced by AMPK siRNA. Thus, P2Y6R has a crucial role in β-cell function, suggesting its potential as a therapeutic target in diabetes.

Abstract
4-Alkyloxyimino derivatives of pyrimidine nucleotides display high potency as agonists of certain G protein-coupled P2Y receptors (P2YRs). In an effort to functionalize a P2Y6R agonist for fluorescent labeling, we probed two positions (N4 and γ-phosphate of cytidine derivatives) with various functional groups, including alkynes for click chemistry. Functionalization of extended imino substituents at the 4 position of the pyrimidine nucleobase of CDP preserved P2Y6R potency generally better than γ-phosphoester formation in CTP derivatives. Fluorescent Alexa Fluor 488 conjugate 16 activated the human P2Y6R expressed in 1321N1 human astrocytoma cells with an EC50 of 9 nM, and exhibited high selectivity for this receptor over other uridine nucleotide-activated P2Y receptors. Flow cytometry detected specific labeling with 16 to P2Y6R-expressing but not to wild-type 1321N1 cells. Additionally, confocal microscopy indicated both internalized 16 (t1/2 of 18 min) and surface-bound fluorescence. Known P2Y6R ligands inhibited labeling. Theoretical docking of 16 to a homology model of the P2Y6R predicted electrostatic interactions between the fluorophore and extracellular portion of TM3. Thus, we have identified the N4-benzyloxy group as a structurally permissive site for synthesis of functionalized congeners leading to high affinity molecular probes for studying the P2Y6R.
