The complex of Fas-associated factor 1 with Hsp70 stabilizes the adherens junction integrity by suppressing RhoA activation

引用

Journal of Molecular Cell Biology 2022年第6期14卷 14-29页

作者： Soonhwa Song Joon Kyu Park Sang Chui Shin jae-Jin lee seung Kon Hong In-Kang Song Bokyung Kim Eun Joo Song Kong-Joo lee Eunice EunKyeong Kim Graduate School of Pharmaceutical Sciences College of PharmacyEwha Womans UniversitySeoul 03760Republic of Korea Biomedical Research Institute Korea Institute of Science and Technology(KIST)Seoul 02792Republic of Korea Technology Support Center Korea Institute of Science and Technology(KIST)Seoul 02792Republic of Korea

Fas-associated factor 1 (FAF1) is a scaffolding protein that plays multiple functions, and dysregulation of FAF1 is associated withmany types of diseases such as cancers. FAF1 contains multiple ubiquitin-related domains (UBA, UBL1, UBL2, UAS, and UBX), eachdomain interacting with a specific partner. In particular, the interaction of UBL1 with heat shock protein 70 (Hsp70) is associatedwith tumor formation, although the molecular understanding remains unknown. In this study, the structural analysis revealed thatHis160 of FAF1 is important for its interaction with Hsp70. The association of Hsp70 with FAF1 is required for the interaction withIQGAP1. FAF1 negatively regulates RhoA activation by FAF1–Hsp70 complex formation, which then interacts with IQGAP1. Thesesteps play a key role in maintaining the stability of cell-to-cell junction. We conclude that FAF1 plays a critical role in the structureand function of adherens junction during tissue homeostasis and morphogenesis by suppressing RhoA activation, which induces theactivation of Rho-associated protein kinase, phosphorylation of myosin light chain, formation of actin stress fiber, and disruptionof adherens junction. In addition, depletion of FAF1 increased collective invasion in a 3D spheroid cell culture. These results provideinsightinto how the FAF1–Hsp70 complex acts as a novelregulator ofthe adherens junction integrity. The complex can be a potentialtherapeutic target to inhibit tumorigenesis and metastasis.

Asian Journal of Andrology 2018年第1期20卷 69-74页

This study aimed to investigate perceived ejaculatory function/satisfaction before treatment for lower urinary tract symptoms （LUTS）/benign prostatic hyperplasia （BPH） and to identify associations between specific categories of ejaculatory dysfunctions （EjDs） and LUTS. A total of 1574 treatment-naive men with LUTS/BPH were included in this study. All patients underwent routine evaluation for LUTS/BPH including the International Index of Erectile Function and a 5-item questionnaire developed to assess ejaculatory volume/force/pain/satisfaction/latency time. Patients who had sexual intercourse over the past 4 weeks were classified as sexually active group. A total of 783 patients were categorized as sexually active group. Decreased ejaculatory volume and force were reported by 53.4% and 55.7% of 783 sexually active men, respectively, There was a strong correlation between ejaculatory volume and force. Ejaculatory pain/discomfort, premature ejaculation （PE）, and delayed ejaculation （DE） were reported in 41,0%, 16.3%, and 41.4% of the patients, respectively. Over 40.0% of men without decreased ejaculation volume/force were satisfied with ejaculatory function, whereas approximately 6.0% of men with decreased volume/force were satisfied with ejaculatory function. About 30.0% of men with decreased volume/force had orgasmic dysfunction, while approximately 10.0% of men without decreased volume/force did. Decreased ejaculatory volume or force was associated with LUTS severity after adjusting for other influential factors including testosterone level, erectile function, and prostate size on ultrasonography, but PE or DE or ejaculatory pain/discomfort was not. In conclusion, a considerable portion of men with LUTS/BPH appear to have a variety of EjDs. Ejaculatory volume/force and satisfaction/orgasm do not always appear to be concordant. Ejaculatory volume or force is independently associated with LUTS severity, whereas PE or DE or ejaculatory pain/discomfort is not.

Potentiation of apomorphine effect on sildenafil-induced penile erection in conscious rabbits

引用

Asian Journal of Andrology 2004年第3期6卷 205-209页

作者： jae-Young Park Hwancheol Son Soo Woong Kim jae-seung Paick Department of Urology Seoul National University College of MedicineSeoulKoreaDepartment of UrologySeoul Municipal Boramae HospitalSeoulKoreaDepartment of UrologySeoul National University College of MedicineSeoulKoreaDepartment of UrologySeoul National University College of MedicineSeoulKorea

Aim: To investigate a possible potentiation effect of apomorphine (APO) on sildenafil-induced penile erection in the conscious rabbit. Methods: Erection of male New Zealand White rabbits (3.5-4.0 kg, n=12) was assessed by measuring the length of the uncovered penile mucosa and the duration of erection before and after intravenous administration of agents. After injection of APO (0, 0.05, 0.1 and 0.4 mg/kg), sildenafil was administered intravenously in a dose-response manner (0.5, 1 and 5 mg/kg). In additional experiments, the effect of increasing doses of sildenafil in combination with APO on systemic blood pressure was evaluated. Results: Systemic administration of sildenafil induced a dose-dependent increase in the penile length. Intravenous injection of APO alone did not produce any change in the penile length, while significantly enhanced the penile erection induced by sildenafil. The co-administration of 0.1 mg/kg of APO and 1 mg/kg of sildenafil was found to be the most effective combination in producing penile erection. Intravenous administration of sildenafil caused a concentration-dependent decrease in systemic blood pressure, but no additional decrease was observed with co-administration of APO. Conclusion: APO enhances the penile erection induced by sildenafil in the conscious rabbit without causing an additional decrease in blood pressure.

Electronic nose(e-nose)technology for selectively identifying a target gas through chemoresistive sensors has gained much attention for various applications,such as smart factory and personal health *** overcome the crossreactivity problem of chemoresistive sensors to various gas species,herein,we propose a novel sensing strategy based on a single micro-LED(μLED)-embedded photoactivated(μLP)gas sensor,utilizing the time-variant illumination for identifying the species and concentrations of various target gases.A fast-changing pseudorandom voltage input is applied to the μLED to generate forced transient sensor responses.A deep neural network is employed to analyze the obtained complex transient signals for gas detection and concentration *** proposed sensor system achieves high classification(~96.99%)and quantification(mean absolute percentage error~31.99%)accuracies for various toxic gases(methanol,ethanol,acetone,and nitrogen dioxide)with a single gas sensor consuming 0.53 *** proposed method may significantly improve the efficiency of e-nose technology in terms of cost,space,and power consumption.
