E3 Ligase Rnf145 Regulates Airway Smooth Muscle Cell Proliferation Via The Pp2a-P70s6k Signaling Axis, Vijaya Kumar Gangipangi, Erin O. Curley, Deepak A. Deshpande, Pawan Sharma

Center for Translational Medicine Faculty Papers

Airway smooth muscle (ASM) is a key determinant of airway caliber and a major contributor to structural remodeling in obstructive lung diseases, including asthma and COPD. ASM proliferation is regulated by transcriptional and post-transcriptional mechanisms, including ubiquitin-dependent protein turnover mediated by E3 ubiquitin ligases. Here, we investigated the role of the RING-type E3 ligase RNF145 in mitogenic signaling and ASM cell proliferation. Human ASM cells were transfected with RNF145 shRNA or treated with the E3 ligase inhibitor SMER3, followed by stimulation with fetal bovine serum (FBS) or platelet-derived growth factor (PDGF). RNF145 knockdown or SMER3 treatment dose-dependently inhibited mitogen-induced ASM …

Introduction: Bronchiectasis, currently being recognized worldwide, is an abnormal dilatation of the bronchi and bronchioles brought on by recurrent cycles of inflammation and airway infection. Impaired pulmonary function has a predictive significance in bronchiectasis. When treating patients with suspected or confirmed respiratory diseases, pulmonary function tests (PFT) are useful examinations. Very few studies have been done on PFTs in bronchiectasis. The main aim of this study is to study PFTs in bronchiectasis.

Method: This is a retrospective observational study done on 50 patients over two years at the tertiary care center. The previous records of patients were collected from the …

Center for Translational Medicine Faculty Papers

Background Cigarette smoking remains a primary cause of chronic lung diseases. After a steady decline, smoking rates have recently increased especially with the introduction of newer electronic nicotine delivery devices, and it is also emerging that dual- or poly-product usage is on the rise. Additionally, with the introduction of IQOS (a heated tobacco product) globally, its impact on human health needs to be investigated. In this study we tested if dual exposure (cigarette smoke (CS)+IQOS) is detrimental to lung epithelial cells when compared with CS or IQOS exposure alone.

Methods Human airway epithelial cells (BEAS-2B) were exposed to either CS, …

The University of Louisville Journal of Respiratory Infections

Background

Even though the proportional burden of COPD among never-smokers is significant in both developing and developed nations, accounting for around 30% of all COPD in the community, there is little awareness of the prevalence of COPD in this population. Understanding the molecular processes that underlie COPD in nonsmokers is essential.

Methods

Dataset (GSE146560) was acquired from the Gene Expression Omnibus (GEO). The limma and clusterProfiler software tools were used to identify differentially expressed genes (DEGs) and conduct a functional enrichment analysis respectively.

Results

In all, 10,583 DEGs were found, of which 1,065 were up-regulated and 9,518 were down-regulated. The …

The University of Louisville Journal of Respiratory Infections

During the first two years of the coronavirus disease 2019 (COVID-19) pandemic, nasopharyngeal (NP) specimens were the gold standard for clinical diagnostic testing. As information about the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing the pandemic continued to be shared, it was clear that the virus could be detected in other specimen types during an active infection. The University of Louisville Infectious Diseases Laboratory accepted non-traditional specimen types, most without a paired, positive NP result, for research purposes only to support local epidemiology efforts. A real-time reverse transcription-polymerase chain reaction (RT-PCR) assay originally validated for NP specimens was used …

Consultation/Liaison Psychiatry During Covid-19, Robert Frierson, Steven B Lippmann

The University of Louisville Journal of Respiratory Infections

Consultation/liaison psychiatrists care for people with co-existing medical and psychologic difficulties. The coronavirus pandemic is stressful for patients and their psychiatric caregivers. Patients have lost support systems and harbor fears about exposing family to the virus. COVID-19 sometimes exacerbates previous psychiatric conditions, while diminishing intimacy with physicians. Everyone is oversaturated with COVID-19-related news focusing on rising concerns about the illness and about jobs, school, and housing insecurities.

The psychiatrist maintains a hospital presence despite fear of contracting the disease. Challenges include addressing staff morale, evidencing empathy despite telecommunication devices, and treating anxiety, depression, sleep phobias, post intubation flashbacks, COVID-19-induced cognitive …
