Evaluation of the Diagnostic Performance and Efficacy of Wearable Electrocardiogram Monitoring for Arrhythmia Detection after Cardiac Surgery.

Background: Postoperative atrial fibrillation (A-fib) is a serious complication of cardiac surgery that is associated with increased mortality and morbidity. Traditional 24-hour Holter monitors have limitations, which have prompted the development of innovative wearable electrocardiogram (ECG) monitoring devices. This study assessed a patch-type wearable ECG device (MobiCARE-MC100) for monitoring A-fib in patients undergoing cardiac surgery and compared it with 24-hour Holter ECG monitoring. Methods: This was a single-center, prospective, investigator-initiated cohort study that included 39 patients who underwent cardiac surgery between July 2021 and June 2022. Patients underwent simultaneous monitoring with both conventional Holter and patchtype ECG devices for 24 hours. The Holter device was then removed, and patch-type monitoring continued for an additional 48 hours, to determine whether extended monitoring provided benefits in the detection of A-fib. Results: This 72-hour ECG monitoring study included 39 patients, with an average age of 62.2 years, comprising 29 men (74.4%) and 10 women (25.6%). In the initial 24 hours, both monitoring techniques identified the same number of paroxysmal A-fib in 7 out of 39 patients. After 24 hours of monitoring, during the additional 48-hour assessment using the patch-type ECG device, an increase in A-fib burden (9%→38%) was observed in 1 patient. Most patients reported no significant discomfort while using the MobiCARE device. Conclusion: In patients who underwent cardiac surgery, the mobiCARE device demonstrated diagnostic accuracy comparable to that of the conventional Holter monitoring system.

Adipose Derived Stromal Vascular Fraction and Mesenchymal Stem Cells Improve Angiogenesis in a Rat Hindlimb Ischaemia Model.

OBJECTIVE: This study aimed to investigate the effect of human adipose tissue derived stromal vascular fraction (AD-SVF) and mesenchymal stem cells (AD-MSCs) on blood flow recovery and neovascularisation in a rat hindlimb ischaemia model. METHODS: SVF was isolated using an automated centrifugal system, and AD-MSCs were obtained from adherent cultures of SVF cells. Rats were divided into four groups of six rats each: non-ischaemia (Group 1); saline treated ischaemia (Group 2); SVF treated ischaemia (Group 3); and AD-MSC treated ischaemia (Group 4). Unilateral hindlimb ischaemia was induced in Sprague-Dawley rats via femoral artery ligation. Saline, SVF, or AD-MSCs were injected intramuscularly into the adductor muscle intra-operatively. Cell viability was calculated as the percentage of live cells relative to total cell number. Blood flow improvement, muscle fibre injury, and angiogenic properties were validated using thermal imaging and histological assessment. RESULTS: The viabilities of SVF and AD-MSCs were 83.3% and 96.7%, respectively. Group 1 exhibited no significant temperature difference between hindlimbs, indicating a lack of blood flow changes. The temperature gradient gradually decreased in SVF and AD-MSC treated rats compared with saline treated rats. In addition, only normal muscle fibres with peripherally located nuclei were observed in Group 1. Groups 3 and 4 exhibited significantly fewer centrally located nuclei, indicating less muscle damage compared with Group 2. Regarding angiogenic properties, CD31 staining of endothelial cells showed similar patterns among all groups, whereas expression of vascular endothelial growth factor, as a crucial angiogenesis factor, was enhanced in the SVF and AD-MSC treated groups. CONCLUSION: SVF and AD-MSCs improved blood flow and neovascularisation in a rat hindlimb ischaemia model, suggesting their potential ability to promote angiogenesis. Further extensive research is warranted to explore their potential applications in the treatment of severe lower extremity arterial disease.

Risk Factors and Management of Blunt Inferior Vena Cava Injury: A Retrospective Study.

BACKGROUND: Traumatic inferior vena cava (IVC) injuries are uncommon, but the mortality rate remains high at 38-70%. To date, most studies on traumatic IVC injuries have evaluated blunt rather than penetrating injuries. We aimed to identify the clinical features and risk factors that affect the prognosis of patients with blunt IVC injuries to improve treatment strategies for these patients. METHODS: We retrospectively analyzed patients diagnosed with blunt IVC injury over 8 years at a single trauma center. Clinical and biochemical parameters; transfusion, surgical, and resuscitation methods; associated injuries; intensive care unit stay; and complications data were compared between survival and death groups to identify clinical features and risk factors of blunt IVC injury-related mortality. RESULTS: Twenty-eight patients with blunt IVC injury were included during the study periods. Twenty-five (89%) patients underwent surgical treatment, and the mortality was 54%. The mortality rate according to the IVC injury location was the lowest for supra-hepatic IVC injury (25%, n = 2/8), whereas it was the highest for retrohepatic IVC injury (80%, n = 4/5). In the logistic regression analysis, Glasgow Coma Scale (GCS) (odds ratio [OR] = 0.566, 95% confidence interval [CI] [0.322-0.993], p = 0.047) and red blood cell (RBC) transfusion for 24 h (OR = 1.132, 95% CI [0.996-1.287], p = 0.058) were independent predictors for mortality. CONCLUSIONS: Low GCS score and high-volume packed RBC transfusion requirements for 24 h were significant predictors of mortality in patients with blunt IVC injuries. Unlike IVC injuries caused by penetrating trauma, supra-hepatic IVC injuries caused by blunt trauma have a good prognosis.

Delayed aortic regurgitation after TEVAR procedure: a case report.

BACKGROUND: Acute aortic regurgitation (AR) is uncommon condition and usually results in an emergent situation because the left ventricle does not adapt quickly due to a sudden increase in end-diastolic volume caused by the regurgitant flow. Thoracic endovascular aortic repair (TEVAR) is a procedure that places a stent-graft on the lesion of thoracic aorta through a minimally invasive approach. CASE PRESENTATION: Here we report that a catheter-induced aortic valve injury associated with TEVAR can cause delayed AR, exemplified by the case of a patient who developed acute AR 42 months after TEVAR. For this, aortic valve replacement was performed and the patient was discharged without complications. CONCLUSION: Our results demonstrate that when a catheter-related procedure is performed around the aortic valve, slight injury of the valve can cause aortic insufficiency even 3 years after surgery. Consequently, when performing a catheter-related procedure around the aortic valve, special attention is always required.

Mid-Term Outcomes of Nonoperative Management for Patients with Grade III Blunt Thoracic Aortic Injury.

BACKGROUND: The purpose of our study was to assess the mid-term outcomes of the patients with grade III blunt thoracic aortic injury (BTAI) who were treated non-operatively and to determine the specific conditions for successful NOM. METHODS: We retrospectively reviewed patients with grade III BTAI at a single level 1 trauma center between January 2012 and March 2020, and compared the demographics and outcomes of NOM and thoracic endovascular aortic repair (TEVAR). We also examined the factors contributing to the selection of NOM by calculating the odds ratios for age, sex, initial systolic blood pressure, injury severity score, abbreviated injury scale score, pseudoaneurysm/neck (P/N) ratio, and comorbidity. RESULTS: In total, 46 adults were included. Thirty patients underwent NOM and 19 underwent TEVAR. The time from injury to computed tomography, hospital days, intensive care unit length of stay, and follow-up period showed no difference between the two groups. Aorta-related mortality was not observed in either group. Two patients (7.4%) in the NOM group experienced an increase in pseudoaneurysms: one of them underwent delayed surgical repair without complications, and the other maintained regular follow-up. The odds ratio for selecting NOM was significant when the P/N ratio was < 1.30 (OR = 4.687 [95% CI, 1.229-17.882], p = 0.024). CONCLUSIONS: We suggest that carefully selected patients with BTAI grade III could be observed nonoperatively or treated by delayed intervention on outpatient basis, and a P/N ratio < 1.30 can be used as a cutoff to decide treatment options for BTAI grade III.

Predictors of health-related quality of life after coronary artery bypass graft surgery.

Health-related quality of life (HRQOL) is a multifactorial concept in assessing physical and mental health. This study was performed to evaluate the HRQOL of patients undergoing coronary artery bypass graft (CABG) surgery and the predictors of HRQOL in patients until 1 year after surgery. This cross-sectional study included 110 consecutive patients who underwent elective CABG in a medical center in South Korea. The Short-Form Health Survey, cardiac symptom survey, cardiac self-efficacy, and the Interpersonal Support Evaluation List-12 were used to measure the HRQOL, symptom experience, self-efficacy, and social support, respectively. The regression model explained 42% of the variance in the participants' physical HRQOL. The predictors of the physical HRQOL include the presence of a spouse, post-CABG duration, symptom experience, and self-efficacy. The regression model explained 36% of the variance in the participants' mental HRQOL. The predictors of the mental HRQOL included perceived health status, self-efficacy, and social support. The predictive factors for HRQOL after CABG were the presence of a spouse, post-CABG duration, symptom experience, self-efficacy, and social support. Furthermore, a suitable program and nursing interventions could be implemented to improve the HRQOL of post-CABG patients.

Acute right ventricular failure evoked by trauma induced thyroid storm supported by extracorporeal membrane oxygenation: A case report.

RATIONALE: Cardiac arrest due to thyroid storm is a very rare clinical feature with high mortality that presents as multiorgan dysfunction. The mortality rate under this condition is close to 30%, even with appropriate treatment. Most thyroid storms occur in patients with long-standing untreated hyperthyroidism. PATIENT CONCERNS: A 67-year-old woman, who had no specific medical history, was admitted with stupor mentality after a pedestrian traffic accident. DIAGNOSIS: The patient had a Burch and Wartofsky score of 80, well beyond the criteria for diagnosis of a thyroid storm (>45 points). INTERVENTIONS: Venoarterial extracorporeal membrane oxygenation (ECMO) was performed due to persistent unstable vital signs and findings of right ventricular dysfunction after return of spontaneous circulation after cardiopulmonary resuscitation. Circulatory assist with ECMO was performed for 8 days using a beta blocker, steroids, thionamide, and Lugol iodine solution. OUTCOMES: Myocardial function and thyroid hormone levels were rapidly normalized. The patient's mental state recovered, and patient was discharged on day 36 maintaining medication. LESSONS: Diagnosis of a thyroid storm in patients with multiple trauma is very difficult, because most trauma patients have symptoms of tachycardia, altered mental status, and abdominal pain that appear in thyrotoxic events. However, when unexplained shock without bleeding evidence occurs in patients with multiple trauma, a thyroid function test should be performed to rule out thyroid storm. Moreover, if hyperthyroidism is observed in a trauma patient, even if there is no history of hyperthyroidism, the possibility of a thyroid storm must be considered along with medical support treatment such as ECMO in patient with cardiogenic shock.

CFTR interactome mapping using the mammalian membrane two-hybrid high-throughput screening system.

Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) is a chloride and bicarbonate channel in secretory epithelia with a critical role in maintaining fluid homeostasis. Mutations in CFTR are associated with Cystic Fibrosis (CF), the most common lethal autosomal recessive disorder in Caucasians. While remarkable treatment advances have been made recently in the form of modulator drugs directly rescuing CFTR dysfunction, there is still considerable scope for improvement of therapeutic effectiveness. Here, we report the application of a high-throughput screening variant of the Mammalian Membrane Two-Hybrid (MaMTH-HTS) to map the protein-protein interactions of wild-type (wt) and mutant CFTR (F508del), in an effort to better understand CF cellular effects and identify new drug targets for patient-specific treatments. Combined with functional validation in multiple disease models, we have uncovered candidate proteins with potential roles in CFTR function/CF pathophysiology, including Fibrinogen Like 2 (FGL2), which we demonstrate in patient-derived intestinal organoids has a significant effect on CFTR functional expression.

Translation and Validation of the Korean Version of the Forgotten Joint Score.

BACKGROUD: The Forgotten Joint Score (FJS) is a newly developed patient-reported outcome measure designed to evaluate clinical outcome after total knee arthroplasty (TKA). The FJS is known as a sensitive test with a low ceiling effect. It has been recently translated into many languages. However, no study has reported the validity or reliability of a Korean version of the FJS (K-FJS). Thus, the purpose of this study was to address this issue. METHODS: According to guidelines for cross-cultural adaptation, translation of the English version of the FJS was performed. After obtaining a license from the original developer, 150 patients who had undergone TKA at more than 1 year to less than 5 years ago completed the K-FJS, visual analog scale, Western Ontario and McMaster Universities Osteoarthritis index (WOMAC), and the 36-Item Short Form (SF-36) health survey. To measure test-retest reliability, the K-FJS was completed twice by telephone survey for 100 patients. Responsiveness was retrospectively calculated based on a survey of 50 patients at 3 months and 1 year after surgery. RESULTS: The K-FJS exhibited an excellent reliability (Cronbach's α, 0.967; intraclass correlation coefficient, 0.958; 95% confidence interval, 0.930-0.974). The ceiling effect of the K-FJS was 8.7% (n = 13), which was lower than the WOMAC's ceiling effect (10%). There was no floor effect. The correlation coefficients with WOMAC and SF-36 (physical function) were 0.708 and 0.682, respectively, indicating good construct validity. However, its correlation with mental health subscale of SF-36 was low (r = 0.143). At 3 to 12 months after TKA, the standardized response mean (SRM) was 0.67, which was lower than the SRM of WOMAC (1.03) obtained in the same period. The K-FJS demonstrated strong measurement properties in terms of good construct validity and reliability. CONCLUSIONS: This study suggests that the K-FJS is an excellent instrument that can be used to monitor clinical outcomes after TKA. Using this standardized K-FJS, it would be possible for medical institutions to share more accurate clinical results.

Predictors of unplanned 30-day readmissions after coronary artery bypass graft: a systematic review and meta-analysis of cohort studies.

AIMS: Coronary artery bypass graft (CABG) is one of the most performed cardiac surgery globally. CABG is known to have a high rate of short-term readmissions. The 30-day unplanned readmission rate as a quality measure is associated with adverse health outcomes. This study aimed to identify and synthesize the perioperative risk factors for 30-day unplanned readmission after CABG. METHODS AND RESULTS: We systematically searched seven databases and reviewed studies to identify all eligible English articles published from 1 October 1999 to 30 September 2019. Random-effect models were employed to perform pooled analyses. Odds ratio and 95% confidence interval were used to estimate the risk factors for 30-day unplanned readmission. The 30-day hospital readmission rates after CABG ranged from 9.2% to 18.9% in 14 cohort studies. Among preoperative characteristics, older adults, female, weight loss, high serum creatinine, anticoagulant use or dialysis, and comorbidities were found to be statistically significant. Postoperative complications, prolonged length of hospital stay, and mechanical ventilation were revealed as the postoperative risk factors for 30-day unplanned readmission. However, intraoperative risk factors were not found to be significant in this review. CONCLUSION: Our findings emphasize the importance of a comprehensive assessment during the perioperative period of CABG. Healthcare professionals can perform a readmission risk stratification and develop strategies to reduce readmission rates after CABG using the risk factors identified in this review. Future studies with prospective cohort samples are needed to identify the personal or psychosocial factors influencing readmission after CABG, including perioperative risk factors.

Clinical utility of early postoperative cardiac multidetector computed tomography after coronary artery bypass grafting.

We evaluated the clinical utility of early postoperative cardiac computed tomography (CT) for evaluating left ventricular (LV) function and predicting prognosis in patients who had undergone coronary artery bypass grafting (CABG). Of the 205 patients who underwent CABG from March 2011 to December 2014, 136 underwent early postoperative cardiac CT (within 30 days after CABG) and were enrolled as the study population. The baseline and postoperative follow-up echocardiographic findings, major adverse cardiac events (MACE), and death were recorded for a follow-up period (mean, 5.9 ± 1.1 years). Functional cardiac CT parameters were compared to echocardiographic measurements. The associations between cardiac CT findings and functional recovery and prognosis were evaluated by logistic regression analyses. The LVEF measured via cardiac CT was significantly higher (56.2 ± 11.5% vs. 61.9 ± 12.9%; p = 0.0002) compared to those via early postoperative echocardiography, but the wall motion score index (WMSI) was not significantly different (1.23 ± 0.33 vs. 1.21 ± 0.28, p = 0.5041) between the two methods. During the follow-up period, 17 patients (12.5%) died and 40 (29.4%) developed MACE. Both the LVEF and WMSI measured with early postoperative echocardiography (p = 0.0202 and odds ratio [OR] = 5.0171, p = 0.0039, respectively), and cardiac CT (OR = 0.9625, p = 0.0091 and OR = 14.3605, p = 0.0001, respectively) predicted MACE OR = 0.9630, but only the WMSI, measured using cardiac CT, predicted all-cause death (OR = 10.6017, p = 0.0035). In CABG patients, LVEF and the WMSI measured with early postoperative cardiac CT were comparable with echocardiography and predicted the development of MACE and all-cause death.

The protective effect of alcohol consumption on the incidence of cardiovascular diseases: is it real? A systematic review and meta-analysis of studies conducted in community settings.

BACKGROUND: This study investigated the dose-response relationship between alcohol consumption and CVD incidence, conducting a meta-analysis of studies focusing on residents from local communities. Further, we examined whether light to moderate alcohol consumption had a protective effect on CVD incidence through a sub-group analysis. METHODS: This study conducted a meta-analysis of the relationship between alcohol consumption and CVD incidence, selecting journals published up to December 2017. The alcohol consumption level was classified into non-consumers, light (0.01-10.0 g/day), light to moderate (10.1-20.0 g/day), moderate (20.1-40.0 g/day), moderate to high (40.1-60.0 g/day), and high (> 60.0 g/day) groups. The sub-group analysis was conducted according to the number of comorbidities and age. RESULTS: Seven articles were selected in total for the meta-analysis. The mean Newcastle-Ottawa scale score was 8.14 points, suggesting studies were of high quality. There was a J-shaped dose-response relationship between alcohol consumption level and CVD incidence only in men. In general, light to moderate and moderate consumption lowered CVD incidence (Relative risk (RR) [95% confidence interval (CI)] was 0.68 [0.57-0.81] and 0.72 [0.58-0.90], respectively). In men with 3-4 comorbidities, there were no protective effects of light to moderate and moderate consumption on CVD incidence. In either groups of only men or men and women there were protective effects of light to moderate and moderate consumption on CVD incidence only in those aged between 41 and 65. DISCUSSION: We found that light to moderate and moderate alcohol consumption had a protective effect on CVD incidence, there was no protective effect either in those with at least three comorbidities or people aged 40 or younger. CONCLUSIONS: We conclude that not all local community residents experience a protective effect of light to moderate consumption on CVD incidence. As such, it is necessary to recommend a moderate amount of drinking or less for each individual.

Acute Pulmonary Thromboembolism: 14 Years of Surgical Experience.

BACKGROUND: Pulmonary thromboembolism (PTE) is a life-threatening disease with high mortality. This study aimed to assess the outcomes of surgical embolectomy and to clarify the sustained long-term effects of surgery by comparing preoperative, postoperative, and long-term follow-up echocardiography outcomes. Of 22 survivors, 21 were followed up for a mean (median) period of 6.8±5.4 years (4.2 years). METHODS: We retrospectively reviewed 27 surgical embolectomy cases for massive or submassive acute PTE from 2003 to 2016. Immediate and long-term follow-up outcomes of surgical embolectomy were assessed on the basis of 30-day mortality, long-term mortality, postoperative complications, right ventricular systolic pressure, and tricuspid regurgitation grade. RESULTS: The 30-day and long-term mortality rates were 14.8% (4 of 27) and 4.3% (1 of 23), respectively. Three patients had major postoperative complications, including hypoxic brain damage, acute kidney injury, and endobronchial bleeding, respectively (3.7% each). Right ventricular systolic pressure (median [range], mm Hg) decreased from 62.0 (45.5-78.5) to 31.0 (25.7-37.0, p<0.001). The tricuspid valve regurgitation grade (median [range]) decreased from 1.5 (0.63-2.00) to 0.50 (0.50-1.00, p<0.05). The improvement lasted until the last echocardiographic follow-up. CONCLUSION: Surgical embolectomy revealed favorable mortality and morbidity rates in patients with acute massive or submassive PTE, with sustained long-term improvements in cardiac function.

Performance of dental pattern analysis system with treatment chronology on panoramic radiography.

The present study was conducted to improve human identification based on dental pattern with adopting chronology of dental treatment within the system. Five hundred adult patients were randomly selected, and their initial and recent panoramic radiography images were assumed as antemortem (AM) and postmortem (PM) images, respectively. For each radiographic image, the dental pattern was analyzed. The analysis system was newly developed considering sequence of dental treatment in time order. AM and PM databases were constructed with information of dental patterns, patient age, and gender. For the PM database, age information was stored as the actual age ± 10 years, which was defined as the estimated age. According to dental pattern of PM record, the possible AM records were selected as candidates. Then candidates were sorted in order of dental pattern similarity to the PM record, and the rank of the true AM record was identified. The total 500 AM records were reduced to 14.5 ± 13.4 candidates in average when the dental pattern, gender, and estimated age were considered. When the candidates were sorted in order of similarity, the true AM record received an average ranking of 2.0 ± 2.6. When dental pattern and gender were considered, 46.7 ± 42.3 candidates were selected among 500 records and the true AM record was ranked at 3.0 ± 5.0, in average. The dental pattern analysis adopting dental treatment chronology was contributed to reduce the sample population. This method would become more efficient and comprehensive if the dental pattern analysis process is automatized in the near future.

Quantitative analysis of lard in animal fat mixture using visible Raman spectroscopy.

Food adulteration is a serious issue that requires verification and strict management due to healthcare, morality, and social value problems. In the context of fat, food manufacturers blend lard with vegetable oils or animal fats for convenience and gaining economic benefits. Thus, we herein report the classification of 4 animal fats, e.g., beef tallow, pork lard, chicken fat, duck oil, using Raman spectroscopy combined with simple calculation of intensity ratios of Raman signal at vibrational modes corresponding to unsaturated fatty acids and total fatty acids. Various calculated values of the species were compared to find a feature that is able to classify each fats using Raman peak ratio. As a result, we suggested "Oil gauge (OG)" as a standard feature for classification of the fats in Raman analysis field. Furthermore, a quantification of the lard in other fat was accomplished with good linear correlation using the OG values.

Use of revascularized artery as a recipient in microvascular reconstruction of the lower leg: An analysis of 62 consecutive free flap transfers.

BACKGROUND: This study aimed to demonstrate the safety and reliability of combined preoperative angioplasty and free flap transfer in patients with peripheral arterial occlusive disease (PAOD) by analyzing the surgical outcomes. METHODS: Between October 2011 and October 2015, patients who had undergone lower extremity angiography and subsequent free flap transfer were retrospectively reviewed. Data collected included demographics, perioperative data, and postoperative outcomes. The cases were divided into two groups: one group with microanastomosis performed on revascularized artery by balloon angioplasty and the other group performed on native artery. Multiple logistic regression model using propensity score and linear regression was computed to determine the association between preoperative angioplasty and the surgical outcomes. RESULTS: A total of 62 lower limb reconstruction cases (19 angioplastied cases and 43 nonangioplastied cases) were included in the study. Complications occurred in 6 cases in the angioplastied group and in 11 cases in the control group. The overall limb salvage rate was 100% during the average follow-up of 29.5 months in the angioplastied group and 97.7% in the nonangioplastied control group during the average follow-up of 31.1 months. Preoperative angioplasty was not a significant predictor of increased complications and longer postoperative downtime in logistic and linear regression model, both in the weighted and unweighted model. CONCLUSIONS: The combined approach of preoperative endovascular revascularization and free flap transfer for limb reconstruction in PAOD patients can be performed safely and effectively with acceptable morbidity.

Detecting Membrane Protein-protein Interactions Using the Mammalian Membrane Two-hybrid (MaMTH) Assay.

Protein-protein interactions (PPIs) play an integral role in numerous cellular processes. Membrane protein interactions, in particular, are critical in cellular responses to stresses and stimuli, with dysfunction of these PPIs (e.g., due to aberrant expression and/or mutation of interaction partners) leading to a diverse array of pathological states. Exploration of the interaction space and dynamics of membrane proteins is difficult due to the limitations of current techniques used to study proteins in the biochemically complex environment of biological membranes. In the protocols below, we describe a newly developed membrane protein interaction assay called the Mammalian-Membrane Two-Hybrid (MaMTH), designed specifically for the detection of integral membrane PPIs in the context of living mammalian cells. Prior to using MaMTH, cell lines of interest are genetically modified to encode a reporter of choice. MaMTH "bait" and "prey" constructs of interest are also generated using Gateway cloning technology. The assay is then performed by co-transfection of baits and preys, with bait-prey interaction quantifiably assessed by way of a reporter signal (e.g., light (luciferase), fluorescence (GFP). © 2017 by John Wiley & Sons, Inc.

Recent Progress in CFTR Interactome Mapping and Its Importance for Cystic Fibrosis.

Cystic Fibrosis Transmembrane Conductance Regulator (CFTR) is a chloride channel found in secretory epithelia with a plethora of known interacting proteins. Mutations in the CFTR gene cause cystic fibrosis (CF), a disease that leads to progressive respiratory illness and other complications of phenotypic variance resulting from perturbations of this protein interaction network. Studying the collection of CFTR interacting proteins and the differences between the interactomes of mutant and wild type CFTR provides insight into the molecular machinery of the disease and highlights possible therapeutic targets. This mini review focuses on functional genomics and proteomics approaches used for systematic, high-throughput identification of CFTR-interacting proteins to provide comprehensive insight into CFTR regulation and function.
