Anti-Egfr Aptamer Exhibits Direct Anti-Cancer Effects In Nsclc Cells Harboring Egfr L858r Mutations, Brian J. Thomas, Sania Z. Awan, Trupti Joshi, Mark A. Daniels, David Porciani, Donald H. Burke

Biomedical Sciences

Non-small cell lung cancer (NSCLC) adenocarcinoma (LUAD) is a leading cause of death worldwide. Activating mutations in the tyrosine kinase domain of the oncogene epidermal growth factor receptor (EGFR) are responsible for ~10–50% of all LUAD cases. Although tyrosine kinase inhibitors (TKIs) have been effective in prolonging patient survival and quality of life, acquired resistance and disease progression are inevitable, presenting a clear unmet need for alternative or adjuvant therapeutics. Here we show that an anti-EGFR aptamer (EGFRapt) decreases viability and tumor growth of LUAD cell lines harboring the L858R ± T790M mutation in EGFR. Additionally, we elucidate …

Biomedical Sciences

In mice, the fetal brain is dependent upon the placenta for factors that guide its early development. This linkage between the two organs has given rise to the term, the placenta–brain axis. A similar interrelationship between the two organs may exist in humans. We hypothesize that extracellular vesicles (EVs) released from placental trophoblast (TB) cells transport small RNA and other informational biomolecules from the placenta to the brain where their contents have pleiotropic effects. Here, EVs were isolated from the medium in which human trophoblasts (TBs) had been differentiated in vitro from induced pluripotent stem cells (iPSC) and from cultured …

Many psychiatric conditions have their roots in early development. Individual differences in prenatal brain function (which is influenced by a combination of genetic risk and the prenatal environment) likely interact with individual differences in postnatal experience, resulting in substantial variation in brain functional organization and development in infancy. Neuroimaging has been a powerful tool for understanding typical and atypical brain function and holds promise for uncovering the neurodevelopmental basis of psychiatric illness; however, its clinical utility has been relatively limited thus far. A substantial challenge in this endeavor is the traditional approach of averaging brain data across groups despite individuals …


Limitations And Potential Of Κor Biased Agonists For Pain And Itch Management, Amal El Daibani, Manish K Madasu, Ream Al-Hasani, Tao Che Nov 2024

Limitations And Potential Of Κor Biased Agonists For Pain And Itch Management, Amal El Daibani, Manish K Madasu, Ream Al-Hasani, Tao Che

2020-Current year OA Pubs

The concept of ligand bias is based on the premise that different agonists can elicit distinct responses by selectively activating the same receptor. These responses often determine whether an agonist has therapeutic or undesirable effects. Therefore, it would be highly advantageous to have agonists that specifically trigger the therapeutic response. The last two decades have seen a growing trend towards the consideration of ligand bias in the development of ligands to target the κ-opioid receptor (κOR). Most of these ligands selectively favor G-protein signaling over β-arrestin signaling to potentially provide effective pain and itch relief without adverse side effects associated …

2020-Current year OA Pubs

Craniotubular dysplasia, Ikegawa type (OMIM #619727) denotes the autosomal recessive skeletal disease identified in 2021 featuring blindness acquired in childhood. Five young members of four Indian families harbored a homozygous indel within TMEM53 (OMIM *619722), the gene that encodes transmembrane protein 53 (TMEM53). When intact, TMEM53 spans the nuclear envelope of osteoprogenitor cells, dampens BMP-SMAD signaling, and thereby slows bone formation. Consequently, defective TMEM53 accelerates osteogenesis. Herein, an American boy is compound heterozygous for a novel deletion and a novel missense mutation within TMEM53. His vision and sensorineural hearing became impaired. Radiographic survey revealed diploic thickening of his skull, broad …

Cohort Expansion And Genotype-Phenotype Analysis Of Rab11a-Associated Neurodevelopmental Disorder, Maria Carla Borroto, Jorge L Granadillo, Et Al.

2020-Current year OA Pubs

BACKGROUND: GTPases of the Rab family are important orchestrators of membrane trafficking, and their dysregulation has been linked to a variety of neuropathologies. In 2017, we established a causal link between RAB11A variants and developmental and epileptic encephalopathy. In this study, we expand the phenotype of RAB11A-associated neurodevelopmental disorder and explore genotype-phenotype correlations.

METHODS: We assessed 16 patients with pathogenic or likely pathogenic RAB11A variants, generally de novo, heterozygous missense variants. One individual had a homozygous nonsense variant, although concomitant with a pathogenic LAMA2 variant, which made their respective contributions to the phenotype difficult to discriminate.

RESULTS: We reinforce the …

The Intersection Of Substance Use Stigma And Anti-Black Racial Stigma: A Scoping Review, Rashmi Ghonasgi, Maria E Paschke, Rachel P Winograd, Catherine Wright, Eva Selph, Devin E Banks

2020-Current year OA Pubs

BACKGROUND: Substance use stigma poses a barrier to treatment and recovery from substance use disorder. Stigma is amplified when intersecting with other stigmatized identities, particularly Black racial identity. Despite increasing attention to the intersecting roles of racial and substance use stigma, it is unknown how these stigmas interact to impact treatment and health outcomes among Black people who use drugs. This scoping review examines empirical research documenting differential impacts of race and racism on substance use stigma.

METHODS: We systematically searched PsychInfo and PubMed databases. Eligible studies were conducted in the U.S.; examined a Black sample, subsample, or experimental condition/variable …

Acinetobacter baumannii causes life-threatening infections that are becoming difficult to treat due to increasing rates of multi-drug resistance (MDR) among clinical isolates. This has led the World Health Organization and the CDC to categorize MDR A. baumannii as a top priority for the research and development of new antibiotics. Colistin is the last-resort antibiotic to treat carbapenem-resistant A. baumannii. Not surprisingly, reintroduction of colistin has resulted in the emergence of colistin-resistant strains. Diclofenac is a non-steroidal anti-inflammatory drug used to treat pain and inflammation associated with arthritis. In this work, we show that diclofenac sensitizes colistin-resistant A. baumannii clinical strains …

2020-Current year OA Pubs

BACKGROUND: Neonatal pulmonary embolism is a rare occurrence, especially when idiopathic, instead occurring in patients with identifiable risk factors including severe dehydration, presence or history of a central venous line, or identifiable genetic causes. Given the rarity of paediatric and neonatal pulmonary emboli, few guidelines exist to support the clinician in both the initial resuscitation and ongoing management of the critically ill patient with pulmonary emboli.

CASE SUMMARY: We present a 5-day-old female with unprovoked massive pulmonary embolism and associated haemodynamic compromise. She presented with central cyanosis and weak respiratory effort with hypoxaemia, persistent tachycardia, and hypotension despite initial fluid …

Relationship Between Mri Brain-Age Heterogeneity, Cognition, Genetics And Alzheimer's Disease Neuropathology, Mathilde Antoniades, Pamela Lamontagne, Tammie Benzinger, Daniel S Marcus, John C Morris, Et Al.

2020-Current year OA Pubs

BACKGROUND: Brain ageing is highly heterogeneous, as it is driven by a variety of normal and neuropathological processes. These processes may differentially affect structural and functional brain ageing across individuals, with more pronounced ageing (older brain age) during midlife being indicative of later development of dementia. Here, we examined whether brain-ageing heterogeneity in unimpaired older adults related to neurodegeneration, different cognitive trajectories, genetic and amyloid-beta (Aβ) profiles, and to predicted progression to Alzheimer's disease (AD).

METHODS: Functional and structural brain age measures were obtained for resting-state functional MRI and structural MRI, respectively, in 3460 cognitively normal individuals across an age …
