The initial phase of the COVID-19 pandemic changed the nature of course delivery from largely in-person to exclusively remote, thus disrupting the well-established pedagogy of the Genomics Education Partnership (GEP; https://www.thegep.org ). However, our web-based research adapted well to the remote learning environment. As usual, students who eng...

The Fly-CURE is a genetics-focused multi-institutional Course-Based Undergraduate Research Experience (CURE) that provides undergraduate students with hands-on research experiences within a course. Through the Fly-CURE, undergraduate students at diverse types of higher education institutions across the United States map and characterize novel mutan...

Mutant B.4.1 , generated via EMS mutagenesis in Drosophila melanogaster , was studied by undergraduate students participating in the Fly-CURE. After inducing genetically mosaic tissue in the adult eye, B.4.1 mutant tissue displays a robust increase in cell division and a rough appearance. Complementation mapping and sequence analysis identified a n...

The Genomics Education Partnership (GEP), a consortium of diverse colleges/universities, provides support for integrating genomics research into undergraduate curricula. To increase research opportunities for underrepresented students, GEP is expanding to more community colleges (CC). Genomics research, requiring only a computer with internet acces...

ABSTRACT The Genomics Education Partnership (GEP) engages students in a course-based undergraduate research experience (CURE). To better understand the student attributes that support success in this CURE, we asked students about their attitudes using previously published scales that measure epistemic beliefs about work and science, interest in sci...

A hallmark of the research experience is encountering difficulty and working through those challenges to achieve success. This ability is essential to being a successful scientist, but replicating such challenges in a teaching setting can be difficult. The Genomics Education Partnership (GEP) is a consortium of faculty who engage their students in...

The majority of patients with high-grade serous ovarian cancer (HGSOC) initially respond to chemotherapy; however, most will develop chemotherapy resistance. Gene signatures may change with the development of chemotherapy resistance in this population, which is important as it may lead to tailored therapies. The objective of this study was to compa...

Reduced fitness of admixed individuals is typically attributed to genetic incompatibilities. Although mismatched genomes can lead to fitness changes, in some cases the reduction in hybrid fitness is subtle. The potential role of transcriptional regulation in admixed genomes could provide a mechanistic explanation for these discrepancies, but eviden...

HISTORY On routine examination of a captive-born 9-yr old female Mexican gray wolf (Canis lupus baileyi), a subcutaneous mass (4.7 3 4.1 3 3.1 cm) wasidentified on the medial aspect of its left forelimb.The mass was discrete, firm, and tightly adhered to the surrounding tissues. Skin and hair coat appeared normal, and the remainder of the physical...

Reintroduction of Mexican gray wolves (Canis lupus baileyi) into the wild has had limited success. There is increasing evidence on the critical role of intestinal bacteria in overall health. We aimed to identify and functionally characterize intestinal bacteria residing in the endangered Canis lupus baileyi (C. lupus baileyi) and thriving Great Pla...

Three distinct proliferative signals for multiple myeloma (MM) cell lines induce enhancer of zeste homolog 2 (ezh 2) transcript expression. EZH 2 is a polycomb group protein that mediates repression of gene transcription at the chromatin level through its methyltransferase activity. Normal bone marrow plasma cells do not express ezh2; however, gene...

ANBL-6, a myeloma cell line, proliferates in response to interleukin 6 (IL-6) stimulation, coculture with bone marrow stromal cells, and when harboring a constitutively active mutant N-ras gene. Eighteen samples, including 4 IL-6-treated, 3 mutant N-ras-transfected, 3 normal stroma-stimulated, 2 multiple myeloma (MM) stroma-stimulated, and 6 untrea...

The blue light receptor photoactive yellow protein (PYP) displays rhodopsin-like photochemistry based on thetrans to cis photoisomerization of itsp-coumaric acid chromophore. Here, we report that protein refolding from the acid-denatured state of PYP mimics the last photocycle transition in PYP. This implies a direct link between transient protein...

The photoreceptor photoactive yellow protein (PYP) was used as a model system to study receptor activation and protein folding. Refolding was studied by stopped-flow absorbance spectroscopy for PYP with either a trans or a cis chromophore. Chromophore trans to cis isomerization, the mechanism of light detection by PYP, greatly affects the protein f...

Biological signaling generally involves the activation of a receptor protein by an external stimulus followed by protein-protein interactions between the activated receptor and its downstream signal transducer. The current paradigm for the relay of signals along a signal transduction chain is that it occurs by highly specific interactions between f...
