Louisiana Agriculture Magazine, Fall 2024

Louisiana Agriculture

Questions drive the science behind the LSU AgCenter. Researcher Erin Oberhaus wanted to find data to help educate Louisiana horse owners about the use of an important medication, and a water quality specialist wondered if noneconomic bodies of water, which include agricultural ponds, might help people generate electricity. The research projects that grew from their questions are detailed in this issue of Louisiana Agriculture.

Also in this issue, scientists share the results from important soybean studies, and the AgCenter farm to school team shares success stories from school gardens across the state.

The Commodification Of Local Food Systems In Bali: Social Media, Processed Foods, And Government Policies., Paisleigh Atwood

Indonesia: Arts, Religion, and Social Change

This study examines the differences in food availability between tourist and rural markets in Bali, focusing on the factors contributing to a diet shift in Bali. Using a mixed-methods approach—including interviews with local residents, observational surveys, and a literature review—this research highlights the influence of tourism, social media, and government policies on food choices and accessibility. Findings reveal a noticeable increase in processed foods in tourist areas, driven by demand for convenience and "Instagrammable" options, while rural markets maintain a higher prevalence of whole foods despite the creeping presence of packaged products. Interviews with participants of different generations further underscore …

Approaching A U.S. Regulatory Framework For Sporeless Seaweed Biotechnology, Gabriela Martinez, Terra Bowling, Catherine M. Janasie, Charlie Doering-Powell, Amalia Aruda Almada

William & Mary Environmental Law and Policy Review

Seaweed farming is the fastest-growing aquaculture sector in the United States. The development of sterile, selectively bred (sporeless) seaweed aims to support the economic viability of future large offshore seaweed operations and minimize the environmental risks of these operations to wild seaweed beds. Farmers have implemented analogous breeding techniques to control and enhance most terrestrial crops and common aquaculture products (e.g., oysters and carp). This Article draws from existing federal and state aquaculture policies to explore four pillars critical to a future sporeless seaweed regulatory framework: ensuring maintained sterility, tracing the geographic origin of seed, securing offshore permits, and facilitating …

The Effects Of Cannabinoids On Migration-Related Protein Expression In Ewing’S Sarcoma, Allison Lashall

Theses

Ewing’s sarcoma is an aggressive pediatric bone cancer that has low five-year survival rates, primarily due to metastatic disease and resistance of recurring tumors to traditional treatment options; therefore, novel treatment options are needed. The compound cannabidiol (CBD) has been shown to reduce cell viability, migration, and invasion in several tumor types, though the cellular mechanism of action is not well understood. Our lab has demonstrated the ability of CBD to reduce viability, migration, and invasion of Ewing’s sarcoma cells in vitro and is investigating differential protein and cytokine expression of known mediators of migration, such as intercellular adhesion molecule …

Characterization Of Developmentally Downregulated Nfe2l3 In Retinal Ganglion Cell Survival And Axon Regeneration, Lucy Homer

Holster Scholar Projects

Retinal ganglion cells (RGCs) are central nervous system projection neurons essential for transmitting visual information from the eye to the brain. Damage to RGCs, caused by conditions such as glaucoma and traumatic optic neuropathy (TON), may lead to vision loss or blindness, as adult RGCs lack regenerative capacity. This study focuses on Nfe2l3 (Nrf3), a developmentally downregulated transcription factor known to mediate cellular responses to oxidative stress, a key pathological event following optic nerve injury. We hypothesized that overexpressing Nfe2l3 in RGCs would enhance their survival and promote axon regeneration after optic nerve crush (ONC) injury. To test this, we …

Ur’S Witness Oak Project Honors Enslaved Ancestors, W. John Hayden

Biology Faculty Publications

This article is about one tree and one cemetery plot. Though the existence of some may have been forgotten, many more burial grounds for the enslaved are known and some of these may still have trees old enough to have “witnessed” the interments of those who toiled so hard, for so long. What better way to remember their contributions to the land that continues to nourish us than by maintaining a living legacy of Witness Tree progeny?

Canola – Essentials For Growing A Successful Crop, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Ensuring the basics of canola agronomy are followed can minimise the financial risk of growing canola, which can be higher than other crops due to high input costs, particularly seed and fertiliser.

Insect Pests And Their Management In Oats, Department Of Primary Industries And Regional Development, Western Australia

Grains and other field crops factsheets

Field pests

Damage from invertebrate pests is generally not a major factor for oat crops, however there is a zero tolerance to live pests in export hay.

Significant damage can occur if pest populations build up. Planning rotations to minimise pest carryover, timely sowing, adequate crop nutrition, and good control of weed and root diseases will assist in reducing the likelihood of crop damage by insect pests. Check crops regularly throughout their growth for field insects.

• Control redlegged earth mite and lucerne flea during the seedling stage if necessary.

• Aphids should be checked for and controlled from flag …

Excessive fructose intake is a risk factor for the development of obesity and its complications. Targeting ketohexokinase (KHK), the first enzyme of fructose metabolism, has been investigated for the management of metabolic dysfunction–associated steatotic liver disease (MASLD). We compared the effects of systemic, small molecule inhibitor of KHK enzymatic activity with hepatocyte-specific, N-acetylgalactosamine siRNA–mediated knockdown of KHK in mice on an HFD. We measured KHK enzymatic activity, extensively quantified glycogen accumulation, performed RNA-Seq analysis, and enumerated hepatic metabolites using mass spectrometry. Both KHK siRNA and KHK inhibitor led to an improvement in liver steatosis; however, via substantially different mechanisms, KHK …

Upregulation Of Fatty Acid Synthase Increases Activity Of Β-Catenin And Expression Of Notum To Enhance Stem-Like Properties Of Colorectal Cancer Cells, Courtney O. Kelson, Josiane Weber Tessmann, Mariah E. Geisen, Daheng He, Chi Wang, Tianyan Gao, B. Mark Evers, Yekaterina Y. Zaytseva

Markey Cancer Center Faculty Publications

Dysregulated fatty acid metabolism is an attractive therapeutic target for colorectal cancer (CRC). We previously reported that fatty acid synthase (FASN), a key enzyme of de novo synthesis, promotes the initiation and progression of CRC. However, the mechanisms of how upregulation of FASN promotes the initiation and progression of CRC are not completely understood. Here, using Apc/VillinCre and ApcMin mouse models, we show that upregulation of FASN is associated with an increase in activity of β-catenin and expression of multiple stem cell markers, including Notum. Genetic and pharmacological downregulation of FASN in mouse adenoma organoids decreases the activation of β-catenin …

Pulmonary Vascular Manifestations Of Hereditary Haemorrhagic Telangiectasia, Sarah Cullivan, Barry Kevane, Brian Mccullagh, Terry M O'Connor, Robin Condliffe, Sean Gaine

Children’s Nutrition Research Center Staff Publications

Hereditary haemorrhagic telangiectasia (HHT) is an autosomal dominant, multisystem disorder that manifests with a spectrum of disease including cardiopulmonary complications. HHT is characterised by aberrant signalling via the transforming growth factor β (TGFβ) pathway, with loss of vascular integrity, angiogenesis and vascular dysplasia. The disease has an estimated prevalence of 1 in 5000 persons and the penetrance increases with increasing age. HHT commonly presents with epistaxis and telangiectasia, while visceral arteriovenous malformations are not uncommon. Mutations in the ENG, ACVRL1 and MADH4 genes account for 97% of all HHT cases, and it is recommended that genetic tests are used in …

Benefits Of Calorie Restriction In Mice Are Mediated Via Energy Imbalance, Not Absolute Energy Or Protein Intake, Daniel L Smith, Sharon E Mitchell, Maria S Johnson, Victoria K Gibbs, Stephanie Dickinson, Beate Henschel, Rui Li, Kathryn A Kaiser, Daniella E Chusyd, Andrew W Brown, David B Allison, John R Speakman, Tim R Nagy

Caloric restriction (CR) results in reduced energy and protein intake, raising questions about protein restriction's contribution to CR longevity benefits. We kept ad libitum (AL)-fed male C57BL/6J mice at 27°C (AL27) and pair-fed (PF) mice at 22°C (22(PF27)). The 22(PF27) group was fed to match AL27 while restricted for calories due to cold-induced metabolism. The 22(PF27) mice had significantly lower body weight, lean mass, fat mass, leptin, IGF-1, and TNF-α levels than AL27 mice (p< 0.001 for all). Manipulations over ~11 weeks resulted in significant differences in body temperature, physical activity, and expression of key genes linked to hunger in the hypothalamus. Survival was significantly greater in 22(PF27) compared to AL27 overall (p< 0.001). CR in the context of equivalent energy and protein intake resulted in hormonal, metabolic, and physiological benefits and extended longevity. Hence, energy imbalance, rather than low energy or protein intake per se, mediates the benefits of CR.

Understanding sex disparities in modifiable risk factors across the lifespan is essential for crafting individualized intervention strategies. We aim to investigate age-related sex disparity in cardiometabolic phenotypes in a large nationwide Chinese cohort. A total of 254,670 adults aged 40 years or older were selected from a population-based cohort in China. Substantial sex disparities in the prevalence of metabolic diseases were observed across different age strata, particularly for dyslipidemia and its components. Generalized additive models were employed to characterize phenotype features, elucidating how gender differences evolve with advancing age. Half of the 16 phenotypes consistently exhibited no sex differences, while …

Inhibition Of Hepatic Oxalate Overproduction Ameliorates Metabolic Dysfunction-Associated Steatohepatitis, Sandeep Das, Alexandra C Finney, Sumit Kumar Anand, Sumati Rohilla, Yuhao Liu, Nilesh Pandey, Alia Ghrayeb, Dhananjay Kumar, Kelley Nunez, Zhipeng Liu, Fabio Arias, Ying Zhao, Brenna H Pearson-Gallion, M Peyton Mckinney, Koral S E Richard, Jose A Gomez-Vidal, Chowdhury S Abdullah, Elizabeth D Cockerham, Joseph Eniafe, Andrew D Yurochko, Tarek Magdy, Christopher B Pattillo, Christopher G Kevil, Babak Razani, Md Shenuarin Bhuiyan, Erin H Seeley, Gretchen E Galliano, Bo Wei, Lin Tan, Iqbal Mahmud, Ida Surakka, Minerva T Garcia-Barrio, Philip L Lorenzi, Eyal Gottlieb, Eduardo Salido, Jifeng Zhang, A Wayne Orr, Wanqing Liu, Monica Diaz-Gavilan, Y Eugene Chen, Nirav Dhanesha, Paul T Thevenot, Ari J Cohen, Arif Yurdagul, Oren Rom

The incidence of metabolic dysfunction-associated steatohepatitis (MASH) is on the rise, and with limited pharmacological therapy available, identification of new metabolic targets is urgently needed. Oxalate is a terminal metabolite produced from glyoxylate by hepatic lactate dehydrogenase (LDHA). The liver-specific alanine-glyoxylate aminotransferase (AGXT) detoxifies glyoxylate, preventing oxalate accumulation. Here we show that AGXT is suppressed and LDHA is activated in livers from patients and mice with MASH, leading to oxalate overproduction. In turn, oxalate promotes steatosis in hepatocytes by inhibiting peroxisome proliferator-activated receptor-α (PPARα) transcription and fatty acid β-oxidation and induces monocyte chemotaxis via C-C motif chemokine ligand 2. In …

Temporal ordering of cellular events offers fundamental insights into biological phenomena. Although this is traditionally achieved through continuous direct observations1,2, an alternative solution leverages irreversible genetic changes, such as naturally occurring mutations, to create indelible marks that enables retrospective temporal ordering3–5. Using a multipurpose, single-cell CRISPR platform, we developed a molecular clock approach to record the timing of cellular events and clonality in vivo, with incorporation of cell state and lineage information. Using this approach, we uncovered precise timing of tissue-specific cell expansion during mouse embryonic development, unconventional developmental relationships between cell …

Intercellular Mitochondrial Transfer Contributes To Microenvironmental Fate Redirection Of Mammary Cancer Cells, Julie Sofie Bjerring

Biomedical Sciences Theses & Dissertations

The dynamic cellular microenvironment, made up of resident cells and various macromolecules, differs markedly across tissues in the body. The multidirectional signals that cells receive from this microenvironment, along with the signaling they send back, heavily influence their physiology and behavior. Recent important findings have further validated this notion as the mammary microenvironment has been shown to suppress tumor progression by redirecting cancer cells to adopt a normal mammary epithelial progenitor fate in vivo. However, the mechanism(s) driving changes in metabolic reprogramming and cancer fate redirection is understudied. The work presented in this dissertation focuses on exploring the impact of …
