School of Medicine Faculty Publications

Background: Triple negative breast cancer (TNBC) is an aggressive subtype of breast cancer characterized by the lack of estrogen receptor, progesterone receptor, and HER2. Our lab previously characterized miR-3189-3p as a microRNA with potent anti-cancer activity against glioblastoma. Here, we hypothesized a similar activity in TNBC cells. As miR-3189-3p is predicted to target a variety of RNA binding proteins, we further hypothesized an inhibitory effect of this miRNA on protein synthesis. Methods: MDA-MB-231 and MDA-MB-468 cells were used to investigate the effect of miR-3189-3p on cell proliferation, migration, and invasion. TGCA database was used to analyze the expression of miR-3189-3p, …

Dance Of The Golgi: Understanding Golgi Dynamics In Cancer Metastasis, Rakhee Bajaj, Amanda N Warner, Jared F Fradette, Don L Gibbons

Faculty, Staff and Student Publications

The Golgi apparatus is at the center of protein processing and trafficking in normal cells. Under pathological conditions, such as in cancer, aberrant Golgi dynamics alter the tumor microenvironment and the immune landscape, which enhances the invasive and metastatic potential of cancer cells. Among these changes in the Golgi in cancer include altered Golgi orientation and morphology that contribute to atypical Golgi function in protein trafficking, post-translational modification, and exocytosis. Golgi-associated gene mutations are ubiquitous across most cancers and are responsible for modifying Golgi function to become pro-metastatic. The pharmacological targeting of the Golgi or its associated genes has been …

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare hematologic malignancy with poor outcomes with conventional therapy. Nearly 100% of BPDCNs overexpress interleukin 3 receptor subunit alpha (CD123). Given that CD123 is differentially expressed on the surface of BPDCN cells, it has emerged as an attractive therapeutic target. UCART123 is an investigational product consisting of allogeneic T cells expressing an anti-CD123 chimeric antigen receptor (CAR), edited with TALEN

Hematopoietic stem cell transplant (HSCT) is a curative option for patients with high-risk acute lymphoblastic leukemia (ALL), but relapse remains a major cause of treatment failure. To prevent disease relapse, we prepared and infused donor-derived multiple leukemia antigen-specific T cells (mLSTs) targeting PRAME, WT1, and survivin, which are leukemia-associated antigens frequently expressed in B- and T-ALL. Our goal was to maximize the graft-versus-leukemia effect while minimizing the risk of graft-versus-host disease (GVHD). We administered mLSTs (dose range, 0.5 × 107 to 2 × 107 cells per square meter) to 11 patients with ALL (8 pediatric, 3 adult), and observed no …

Rhabdomyosarcoma (RMS) is a pediatric myogenic soft tissue sarcoma. The Fusion-Positive (FP) subtype expresses the chimeric protein PAX3-FOXO1 (P3F) while the Fusion-Negative (FN) is devoid of any gene translocation. FP-RMS and metastatic FN-RMS are often unresponsive to conventional therapy. Therefore, novel therapeutic approaches are needed to halt tumor progression. NOTCH signaling has oncogenic functions in RMS and its pharmacologic inhibition through γ-secretase inhibitors blocks tumor growth in vitro and in vivo. Here, we show that NOTCH signaling blockade resulted in the up-regulation and phosphorylation of the MET oncogene in both RH30 (FP-RMS) and RD (FN-RMS) cell lines. Pharmacologic inhibition of …

Genetic susceptibility for xerostomia, a common sequela of radiotherapy and chemoradiotherapy for head and neck cancer, is unknown. Therefore, to identify genetic variants associated with moderate to severe xerostomia, we conducted a GWAS of 359 long-term oropharyngeal cancer (OPC) survivors using 579,956 autosomal SNPs. Patient-reported cancer treatment-related xerostomia was assessed using the MD Anderson Symptom Inventory. Patient response was dichotomized as moderate to severe or none to mild symptoms. In our study, 39.2% of OPC survivors reported moderate to severe xerostomia. Our GWAS identified eight SNPs suggestively associated with higher risk of moderate to severe xerostomia in six genomic regions …

The RB1 gene is frequently mutated in human cancers but its role in tumorigenesis remains incompletely defined. Using an induced pluripotent stem cell (iPSC) model of hereditary retinoblastoma (RB), we report that the spliceosome is an up-regulated target responding to oncogenic stress in RB1-mutant cells. By investigating transcriptomes and genome occupancies in RB iPSC–derived osteoblasts (OBs), we discover that both E2F3a, which mediates spliceosomal gene expression, and pRB, which antagonizes E2F3a, coregulate more than one-third of spliceosomal genes by cobinding to their promoters or enhancers. Pharmacological inhibition of the spliceosome in RB1-mutant cells leads to global intron retention, decreased cell …

Subgroup-Specific Dose Finding For Phase I-Ii Trials Using Bayesian Clustering, Alexandra Curtis, Brian Smith, Andrew G. Chapple

School of Medicine Faculty Publications

In most models and algorithms for dose-finding clinical trials, it is assumed that the trial participants are homogeneous—the optimal dose is the same for all those who qualify for the trial. However, if there are heterogeneous populations who may benefit from the same treatment, it is inefficient to conduct dose-finding separately for each group, and assuming homogeneity across all subpopulations may lead to identification of the incorrect dose for some (or all) subgroups. To accommodate heterogeneity in dose-finding trials when both efficacy and toxicity outcomes must be used to identify the optimal dose (as in immunotherapeutic oncology treatments), we utilize …


The Impact Of Dietary Fiber On Breast Cancer Incidence, Peyton North Apr 2022

The Impact Of Dietary Fiber On Breast Cancer Incidence, Peyton North

Epsilon Sigma at-Large Research Conference

Abstract

Introduction & Background

The role of dietary fiber in breast cancer etiology remains unclear. A negative correlation may be due to fiber’s ability to stave off obesity and aid in the extraction of serum estrogen, two known risk factors for the disease. Effects may differ by source, and type, of fiber. Most of the data available is from research with non-Hispanic white women. However, fiber intake may vary significantly across cultures.

Purpose Statement & Question

The research sought to investigate whether an increased intake of dietary fiber was associated with a corresponding decrease in the incidence of breast cancer. …

In this study, we report the effects of depleting cytospin-A (CYTSA), also known as the sperm antigen with calponin homology and coiled-coil domain (SPECC1L) protein, on the proliferation and migration of colorectal cancer (CRC) cells. Mutations in this protein have been previously linked to different developmental disorders. In our studies, depletion of CYTSA in various CRC cells led to significant decreases in proliferation, increases in cell death, and increased formation of multinucleated cells. Knocking down CYTSA also led to severe inhibition of CRC cell migration and invasion. These effects could be related to a significant decrease in the …

Breast Cancer survivors diagnosed with secondary lymphedema have decreased quality of life and experience greater challenges when attempting to return to work compared to survivors who do not have secondary lymphedema. Limited research is available in understanding the impact breast cancer-related lymphedema has on survivors transitioning from traditional medical care to return to work. Occupational therapists specializing in Lymphedema therapy have the unique training skills and knowledge to address the challenges this population faces, as well as the tools needed to educate patients and their family members on how to manage returning to work, and make any adaptations to their …

Overgrowth due to growth hormone (GH) excess affects approximately 10% of patients with neurofibromatosis type 1 (NF1) and optic pathway glioma (OPG). Our aim is to describe the clinical, biochemical, pathological, and genetic features of GH excess in a retrospective case series of 10 children and adults with NF1 referred to a tertiary care clinical research center. Six children (median age = 4 years, range of 3−5 years), one 14-year-old adolescent, and three adults (median age = 42 years, range of 29−52 years) were diagnosed with NF1 and GH excess. GH excess was confirmed by the failure to suppress GH …

Lenalidomide mechanism of action has been shown to modulate the different components of the immune system. A 68-year-old lady presented to us with severe backache and was then diagnosed with MM. Lenalidomide started as per protocol along with dexamethasone. Later, she presented with complaints of generalized weakness and her workup showed significant blast cells with Pan-B-cell markers consistent with secondary B-ALL. The reported incidence of secondary Acute Lymphocytic Leukemia is 2.3%. The development of more aggressive neoplasm in a patient with prior malignancy dictates a poor outcome and hence such patients should be enrolled in a clinical trial whenever available
