Rice blast caused by Magnaporthe oryzae poses a major threat to world food supply. Conditions conducive to the disease include insufficient light. Our previous studies found that light-dependent phosphorylation of light-harvesting complex II protein (LHCB5) mediates rice immunity; however, the underlying mechanisms, in particular, the upstream regulators of LHCB5 phosphorylation, remain unknown. Here, we show that OsLIKE1 functions as a lectin receptor-like kinase (LecRLK) to play a critical role in rice resistance against M. oryzae. OsLIKE1 interacts with and phosphorylates LHCB5. In addition, we find two phosphorylation sites in the kinase domain of OsLIKE1 important for its auto-phosphorylation and phosphorylation …

Racial disparities in incidence and outcomes of triple-negative breast cancer (TNBC) have been attributed to ancestry, socioeconomic factors and/or obesity. We studied 253 TNBCs from 128 Black and 125 White women. Arms were balanced for age, AJCC stage, histological grade and molecular subtypes, and differed significantly in BMI distribution, obesity, and Area Deprivation Index. We examined survival rates, whole-transcriptome RNASeq and genetic ancestry. In our sample, Black race or obesity were not intrinsically predictive of poor outcomes. TNBC molecular portraits varied with stage and biological aggressiveness, irrespective of race. We identified a novel group of TNBCs with a distinctive luminal-like …

School of Graduate Studies Faculty Publications

Triple-negative breast cancer (TNBC) is one of the most aggressive subtypes of breast cancer, with limited targeted treatment options and poor clinical outcomes. HER3 has recently emerged as a promising therapeutic target, with HER3-directed antibody–drug conjugates advancing to Phase III clinical trials for non-small cell lung cancer. However, the downstream molecular mechanisms by which HER3 promotes TNBC progression remain poorly defined. In this study, we uncovered a previously unrecognized HER3/miR-34b-5p/PHF8 signaling axis that drives TNBC cell proliferation and tumor growth. Mechanistically, HER3 activation suppresses the tumor-suppressive microRNA miR-34b-5p, resulting in the upregulation of the histone demethylase PHF8 (KDM7B), which in …

Non-coding RNAs including miRNAs, long-ncRNAs, and circular RNAs play crucial roles in cell-to-cell communication and epigenetic regulation. They control gene expression at multiple levels, including transcriptional, post-transcriptional, and translational, thereby influencing associated signaling pathways. Encapsulated within exosomes, micro-vesicles, and apoptotic bodies, ncRNAs can be transported between cells while being protected from harsh environmental conditions. Studies have shown various expression patterns across different cell types and in various physiological and pathological states. However, the precise correlations and extent of their contribution to diseases are still under investigation. Recent studies have reported the involvement of extracellular vesicle-associated ncRNAs in the pathogenesis of …

5-Methylcytosine (5mC) is the most common DNA modification in the human genome. Bisulfite conversion combined with short-read sequencing captures this modification at single-nucleotide resolution but introduces PCR duplication bias and limits co-methylation analysis between distant cytosines. To resolve these limitations, we used nanopore long-read sequencing to profile human methylation and performed long-range co-methylation analysis with native DNA modification information. We analyzed the nanopore demo data in the adaptive sampling sequencing targeting the CpG islands and applied the linkage disequilibrium (LD) R to identified methylation haplotype blocks (MHBs). We found that the cancer genome exhibited significantly smaller MHBs, higher CpG density, …

Neoadjuvant chemotherapy (NAC) is a critical component of breast cancer treatment, but the molecular mechanisms underlying resistance remain poorly understood. This study aimed to identify transcriptomic changes associated with NAC resistance across four breast cancer subtypes: Luminal A, Luminal B/HER2-positive, Luminal B/HER2-negative, and Triple-Negative Breast Cancer (TNBC). RNA-seq analysis was performed on paired pre- and post-NAC breast cancer samples from 32 nonresponders. Differentially expressed genes (DEGs) were identified, and functional enrichment analyses were conducted. Protein-protein interaction (PPI) networks were constructed to identify hub genes. Tumor microenvironment (TME) infiltration was estimated using deconvolution algorithms. The results revealed distinct gene expression profiles …

Triple-negative breast cancer (TNBC) is an aggressive, heterogeneous subtype of breast cancer. miRNAs play an essential role in TNBC pathogenesis and prognosis. Obesity is linked with an increased risk for several cancers, including breast cancer. Obesity is also related to the dysregulation of miRNA expression in adipose tissues. However, there is limited knowledge about race- and obesity-specific differential miRNA expression in TNBC. We performed miRNA sequencing of 48 samples (24 tumor and 24 adjacent non-tumor tissues) and RNA sequencing of 24 tumors samples from Black (AA) and White (EA) TNBC patients with or without obesity. We identified 55 miRNAs exclusively …

Stratified medicine holds great promise to tailor treatment to the needs of individual patients. While genetics holds great potential to aid patient stratification, it remains a major challenge to operationalize complex genetic risk factor profiles to deconstruct clinical heterogeneity. Contemporary approaches to this problem rely on polygenic risk scores (PRS), which provide only limited clinical utility and lack a clear biological foundation. To overcome these limitations, we develop the CASTom-iGEx approach to stratify individuals based on the aggregated impact of their genetic risk factor profiles on tissue specific gene expression levels. The paradigmatic application of this approach to coronary artery …

A critical unmet medical need in prostate cancer (PCa) clinical management centers around distinguishing indolent from aggressive tumors. Traditionally, Gleason grading has been utilized for this purpose. However, tumor classification using Gleason Grade 7 is often ambiguous, as the clinical behavior of these tumors follows a variable clinical course. This study aimed to investigate the application of machine learning techniques (ML) to classify patients into indolent and aggressive PCas. We used gene expression data from The Cancer Genome Atlas and compared gene expression levels between indolent and aggressive tumors to identify features for developing and validating a range of ML …

Introduction: Whole genome sequencing (WGS) of bacterial isolates can be used to identify antimicrobial resistance (AMR) genes. Previous studies have shown that genotype-based AMR has variable accuracy for predicting carbapenem resistance in carbapenem-resistant Enterobacterales (CRE); however, the majority of these studies used short-read platforms (e.g. Illumina) to generate sequence data. In this study, our objective was to determine whether Oxford Nanopore Technologies (ONT) long-read WGS would improve detection of carbapenem AMR genes with respect to short-read only WGS for nine clinical CRE samples. We measured the minimum inhibitory breakpoint (MIC) using two phenotype assays (MicroScan and ETEST) for six antibiotics, …

In a patient diagnosed with both Kallmann syndrome (KS) and intellectual disability (ID), who carried an apparently balanced translocation t(7;12)(q22;q24)dn, array comparative genomic hybridization (aCGH) disclosed a cryptic heterozygous 4.7 Mb deletion del(12)(p11.21p11.23), unrelated to the translocation breakpoint. This novel discovery prompted us to consider the possibility that the combination of KS and neurological disorder in this patient could be attributed to gene(s) within this specific deletion at 12p11.21-12p11.23, rather than disrupted or dysregulated genes at the translocation breakpoints. To further support this hypothesis, we expanded our study by screening five candidate genes at both breakpoints of the chromosomal translocation …

Patients with triple-negative breast cancer (TNBC) have a poor prognosis and high relapse rate due to limited therapeutic options. This study was conducted to determine the mechanisms of action of panobinostat, a pan-inhibitor of histone deacetylase (HDAC) and FDA-approved medication for multiple myeloma, in TNBC and to provide a rationale for effective drug combinations against this aggressive disease. RNA sequencing analyses of the claudin-low (CL) TNBC (MDA-MB-231) cells untreated or treated with panobinostat were performed to identify the differentially expressed genes. Adaptive alterations in gene expression were analyzed and validated in additional CL TNBC cells. Tumor xenograft models were used …
