The Importance Of Community Rehabilitation: Evaluating Effectiveness Of Tennessee Interventions, Sarah Grace Knight

Masters Theses

Rehabilitation for offenders has been a topic of discussion for decades. While the system expresses that rehabilitation is the best method of practice, statistics show that these individuals still struggle to reenter society successfully. This study addresses environmental factors and barriers that can make the reentry process difficult and increase chances of recidivism. Additionally, this article takes a look at the state of Tennessee in particular, considering its high crime and recidivism rates. While many states have programs in place, it is apparent that the government needs to focus on creating more stable financial budgets for both community and prison …

Apoptosis is an evolutionarily conserved cell death pathway that plays a crucial role in maintaining tissue homeostasis, orchestrating organismal development, and eliminating damaged cells. Dysregulation of apoptosis can contribute to the pathogenesis of malignant tumors and neurodegenerative diseases. Anticancer drugs typically possess the capacity to induce apoptosis in tumor cells. The Bcl-2 protein family, consisting of 27 members in humans, serves as the key regulator of mitochondrial function. This family can be divided into two functional groups: anti-apoptotic proteins (e.g., Bcl-2, Bcl-xl, Mcl-1) and pro-apoptotic proteins (e.g., Bad, Bax). Mcl-1 exerts its function by binding pro-apoptotic Bcl-2 proteins thereby preventing …

Predicting Mutation-Induced Allosteric Changes In Structures And Conformational Ensembles Of The Abl Kinase Using Alphafold2 Adaptations With Alanine Sequence Scanning, Nishank Raisinghani, Mohammed Alshahrani, Grace Gupta, Gennady M. Verkhivker

Mathematics, Physics, and Computer Science Faculty Articles and Research

Despite the success of AlphaFold2 approaches in predicting single protein structures, these methods showed intrinsic limitations in predicting multiple functional conformations of allosteric proteins and have been challenged to accurately capture the effects of single point mutations that induced significant structural changes. We examined several implementations of AlphaFold2 methods to predict conformational ensembles for state-switching mutants of the ABL kinase. The results revealed that a combination of randomized alanine sequence masking with shallow multiple sequence alignment subsampling can significantly expand the conformational diversity of the predicted structural ensembles and capture shifts in populations of the active and inactive ABL states. …

Ret Mutated Non-Small Cell Lung Cancer (Nsclc) In Association With Patients From Central America, Lily Z. Chen, William J. Gibson, Brian C. Boulmay

School of Medicine Faculty Publications

The rearranged during transfection (RET) gene is on chromosome 10 (10q11.2) and normally encodes a receptor tyrosine kinase that plays a role in the development of the kidney, nervous, and respiratory systems. Aberrant RET gene activation can occur through gene mutations, gene fusions, or over expression leading to uncontrolled cell growth and the development of malignancy. The RET gene was first identified in 1985 as a protooncogene playing a role in the pathogenesis of lymphoma, and mutations are now associated with numerous cancers including lung, thyroid, breast, colon, prostate, and kidney. Activating RET mutations are estimated to occur in 1-2% …

Sequence-To-Expression Approach To Identify Etiological Non-Coding Dna Variations In P53 And Cmyc-Driven Diseases, Katherine Kin, Shounak Bhogale, Lisha Zhu, Derrick Thomas, Jessica Bertol, W Jim Zheng, Saurabh Sinha, Walid D Fakhouri

Faculty, Staff and Student Publications

Disease risk prediction based on genomic sequence and transcriptional profile can improve disease screening and prevention. Despite identifying many disease-associated DNA variants, distinguishing deleterious non-coding DNA variations remains poor for most common diseases. In this study, we designed in vitro experiments to uncover the significance of occupancy and competitive binding between P53 and cMYC on common target genes. Analyzing publicly available ChIP-seq data for P53 and cMYC in embryonic stem cells showed that ~344-366 regions are co-occupied, and on average, two cis-overlapping motifs (CisOMs) per region were identified, suggesting that co-occupancy is evolutionarily conserved. Using U2OS and Raji cells untreated …

Synergistic Effects Of Biological Stimuli And Flexion Induce Microcavities Promote Hypertrophy And Inhibit Chondrogenesis During In Vitro Culture Of Human Mesenchymal Stem Cell Aggregates, Bo Zhang, Jim Berilla, Sungwoo Cho, Rodrigo A. Somoza, Jean F. Welter, Harihara Baskaran

Faculty Scholarship

Interzone/cavitation are key steps in early stage joint formation that have not been successfully developed in vitro. Further, current models of endochondral ossification, an important step in early bone formation, lack key morphology morphological structures such as microcavities found during development in vivo. This is possibly due to the lack of appropriate strategies for incorporating chemical and mechanical stimuli that are thought to be involved in joint development. We designed a bioreactor system and investigated the synergic effect of chemical stimuli (chondrogenesis-inducing [CIM] and hypertrophy-inducing medium [HIM]) and mechanical stimuli (flexion) on the growth of human mesenchymal stem cells (hMSCs) …

Kindlin-2 Regulates The Oncogenic Activities Of Integrins And Tgf-Β In Triple-Negative Breast Cancer Progression And Metastasis, Neelum Aziz Yousafzai, Lamyae El Khalki, Wei Wang, Khailid Sossey-Alaoui

Faculty Scholarship

Kindlin-2, an adapter protein, is dysregulated in various human cancers, including triple-negative breast cancer (TNBC), where it drives tumor progression and metastasis by influencing several cancer hallmarks. One well-established role of Kindlin-2 involves the regulation of integrin signaling, achieved by directly binding to the cytoplasmic tail of the integrin β subunit. In this study, we present novel insights into Kindlin-2’s involvement in stabilizing the β1-Integrin:TGF-β type 1 receptor (TβRI) complexes, acting as a physical bridge that links β1-Integrin to TβRI. Loss of Kindlin-2 results in the degradation of this protein complex, leading to the inhibition of downstream oncogenic pathways. We …

Designing A Novel Approach To Cadaveric Dissection And Evaluation Of The Lacrimal Gland Anatomy, Maresa Joanna Mcdowell

Doctoral Dissertations and Projects

During our study, the orbital dissections of 44 cadavers were analyzed, and the lacrimal gland's condition after dissection was evaluated. Medical students previously dissected twenty-two of the cadavers using the dissection steps outlined in Grant’s Dissector. From these, 21 student groups performed orbital dissection using the two approaches outlined in Grant’s Dissector. Post-evaluation of Grant’s anterior approach (GAA) showed that 50% of the lacrimal glands had signs of damage to the orbital lobe, and 88.89% of the palpebral lobe were damaged. When Grant’s supraorbital approach (GSA) was used, 70% of the palpebral lobes showed signs of damage compared to the …
