Updates In Mycobacterial Keratitis Diagnosis And Treatment, Uma L Balakrishnan, Ryan T Wallace, Patricia Chévez-Barrios, Alejandro Arboleda, Masih U Ahmed

Faculty, Staff and Students Publications

Mycobacterial keratitis is an uncommon but challenging form of infectious keratitis, often associated with postsurgical eyes. Clinical presentation is variable and may be difficult to recognize, resulting in delays in diagnosis and challenges in management. Traditional diagnostic techniques from corneal scrapings are limited by slow organism growth and may yield negative results. Treatment is challenging due to antimicrobial resistance and typically requires prolonged multidrug therapy. Advances in diagnostic modalities, antimicrobial therapies, surgical approaches, and adjunctive treatments such as corneal crosslinking have improved clinicians' ability to mitigate or avoid severe visual consequences. Despite these developments, optimal management strategies remain incompletely defined, …

A Strategy To Identify Biliary Atresia Efficiently: A Perspective From A Texas Center, Sanjiv Harpavat, Tebyan A Rabbani, Ashley M Upton, Sridevi Devaraj, Jose A Hernandez, Benjamin L Shneider

Faculty, Staff and Students Publications

Infants with biliary atresia are often diagnosed after 60 days of life because the disease is difficult to detect in its early stages. However, infants treated before 30-45 days of life have the best long-term outcomes. To help accelerate the biliary atresia diagnosis, we have developed a streamlined strategy that involves two sequential tests: (1) direct or conjugated bilirubin measurements and (2) a feeding abdominal ultrasound exam. In this review, the strategy is shared to encourage others to provide feedback as well as to consider incorporating portions into their own clinical workflows.

Faculty, Staff and Students Publications

Alzheimer's disease is a complex and multifactorial disease characterized by two key pathological hallmarks: amyloid-beta plaques and tau neurofibrillary tangles. Recent progress has led to the development and approval of disease-targeted therapies for Alzheimer's disease in the form of anti-amyloid-beta monoclonal antibodies. However, findings suggest that amelioration of multiple pathological drivers may be required to maximize clinical effect. An increasing body of evidence suggests that tau is a critical player in Alzheimer's disease pathophysiology, contributing significantly to neurodegeneration and cognitive decline. There are now several tau-targeting drugs in clinical development. In this review, we build on research and advancements in …

Mir-302 Regulates Pancreatic Progenitor Pool And Pancreatic Size, Ziyue Z Yang, Caroline G Snider, Ronald J Parchem

Faculty, Staff and Students Publications

Disruptions in pancreatic development can lead to health issues such as pancreatic agenesis and congenital diabetes mellitus. Understanding pancreatic organogenesis is critical for elucidating disease mechanisms and developing regenerative therapies. The pancreas consists of endocrine and exocrine cells, both of which are derived from multipotent progenitor cells (MPCs). MPC proliferation and differentiation are tightly controlled by multiple mechanisms, including post-transcriptional regulation by miRNAs. However, these regulatory factors are not fully understood. Here, we profiled miRNA expression in MPCs and identified that mir-302 was highly enriched during the earliest stages of pancreatic development. Loss of mir-302 resulted in reduced pancreatic size …

Surface Marker Identification To Capture Live Circulating Tumor Cells In Metastatic Triple-Negative Breast Cancer, Bree M Lege, Khushali J Patel, Brendan Panici, Ping Gong, Michael T Lewis, Matthew J Ellis, Chonghui Cheng

Faculty, Staff and Students Publications

Metastatic triple-negative breast cancer (TNBC) is highly aggressive and lacks targeted therapies. Circulating tumor cells (CTC) are invaluable for monitoring metastatic tumor progression and treatment response but are difficult to capture because of their rarity and heterogeneity. Surface-based staining for live CTCs is essential to preserve RNA quality in single cells, but current markers tend to perform poorly on more mesenchymal tumor cells such as TNBCs. To enhance live TNBC CTC detection, we developed a workflow for live CTC capture and single-cell RNA sequencing (scRNA-seq). Using a mouse model of metastatic TNBC, we identified four new CTC surface markers, AHNAK2, …

Centrosomes play a fundamental role in nucleating and organizing microtubules in the cell and are vital for faithful chromosome segregation and maintenance of genomic stability. Loss of structural or functional integrity of centrosomes causes genomic instability and is a driver of oncogenesis. Here we identify lysine demethylase 4A (KDM4A), an epigenetic 'eraser' of chromatin methyl marks, as a centrosome-localized protein, visualized at the nanometer-scale resolution. We additionally uncovered that KDM4A demethylase enzymatic activity is required to maintain centrosome homeostasis and integrity; a previously unknown functionality unlinked to altered expression of genes regulating centrosome number. We find that KDM4A interacts with …
