This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Healthy corneas are clear and lack blood vessels, but injuries like alkali burns can trigger neovascularization. This serious complication reduces the patient’s vision and is the leading cause of failure in corneal transplants. Previous studies have suggested that AIP1 (Apoptosis signal-regulating kinase 1-interacting protein) is involved in inflammatory neovascularization induction and that NOX4 (NADPH oxidase 4) is activated by alkali burns. NOX4 can produce reactive oxygen species (ROS) which unbalance the expression of the inflammation-related proteins NLRP3 and NLRP6 (NLR family pyrin domain containing 3 and 6). Researchers recently used a mouse model to examine how AIP1 and NOX4 are related to NLRP3/NLRP6 after corneal alkali burns. Corneal alkali burns decreased AIP1 expression and increased the expression of two pro-angiogenic proteins, clv-IL-1β (cleaved interleukin-1β) and VEGFa (vascular endothelial growth factor A)..."

It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Some proteins are central to many cell signaling processes. One of these key molecules is AKT2. An important kinase involved in cell survival, growth, and metabolism, it has ties to insulin-induced signaling and cancer. AKT2 has a critical role in immune cells such as neutrophils and macrophages; however, although AKT2 is expressed in antibody-producing immune cells called B cells, its function in B cells isn’t clear. In a recent study, researchers sought to understand the role of AKT2 in B cells using AKT2-deficient mice. They found that mice lacking AKT2 had impaired B-cell differentiation. B cells from these mice were not able to form a cluster of molecules called a signalosome in response to B-cell receptor (BCR) signaling, resulting in poor BCR signaling and impaired B cell activation and spreading. These results suggest that as a central orchestrator of signaling, AKT2 function is critical for proper BCR signaling and B cell development, ensuring a functional antibody-mediated immune response..."

It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Gq protein-coupled receptors (GqPCRs) are membrane bound proteins that transmit signals from outside the cell to internal signaling pathways. One of these pathways is the PI3K/AKT pathway, which plays roles in cellular proliferation, survival, metabolism, and differentiation. PI3K/AKT dysregulation is also often implicated in cancers. A previous study determined that activating GqPCRs in certain cells inactivated AKT, which led to a specific type of cell death, JNK-dependent apoptosis. This unique signal seems to play an important role in physiological and pathological events like pituitary development and cardiac hypertrophy. Now, a new study determined that the mechanism of this AKT inactivation relies on another signaling-related protein, PP2A. When the GqPCRs are not activated, a fraction of PP2A "c" subunit is in a dimer complex with another protein, IGBP1 and they are bound to the p85 subunit of PI3K, causing its activation..."

"Immune checkpoints are an effective way that cancers evade the immune system, but they're not the only one. In the case of pancreatic ductal carcinoma, or PDAC, tumor fibrosis also plays an important role. To understand how fibrosis might translate to poor outcomes among patients with PDAC, researchers examined the ARF6-AMAP1 molecular pathway, which research suggests is activated during fibrosis. Findings revealed that AMAP1 correlated with elevated expression of PD-L1, a molecule that tumor cells present on their surface to elude attack by the immune system. AMAP1 was also linked to elevated fibrosis. Consistently, silencing AMAP1 in a mouse model of human PDAC reduced PD-L1 and fibrosis in their tumors. Suppressing the ARF6-AMAP1, therefore, could be one way to ensure that PDAC tumors can’t hide from immune defenses, offering the prospect of more effective immunotherapies for patients with pancreatic ductal carcinoma..."

The video's transcript is also provided in full, with a portion provided below for preview:

"The transcription factor ATF5 plays a vital role in the formation of several cancers, including breast, lung, ovarian, pancreatic, rectal, and liver cancer. But ATF5’s function in esophageal cancer—one of the most common forms of cancer worldwide—remains unclear. To find out, researchers monitored the activity of ATF5 in esophageal cancer tissues. Much like in other cancers, ATF5 was upregulated in esophageal cancer tissues cultured in the lab, and ATF5 overexpression promoted the proliferation, migration, and invasiveness of esophageal cancer cells. Silencing ATF5, however, inhibited these abilities. In fact, in mice, silencing ATF5 hampered tumor growth. ATF5’s role as a lever that triggers tumor growth is believed to occur through an interaction with HIF1, a protein complex also known to promote the growth and spread of tumors. These findings suggest that the known anti-cancer effects of silencing ATF5 might also be powerful against esophageal cancer..."

The video's transcript is also provided in full, with a portion provided below for preview:

"The non-receptor tyrosine kinase Abelson (Abl) is a key player in oncogenesis, causing diseases including chronic myelogenous and acute lymphoblastic leukemia. Drugs targeting Abl kinase activity serve as paradigms of targeted therapy. Drosophila is an ideal model for studying Abl’s function because there is only a single fly Abl family member. In flies, Abl is essential for embryonic morphogenesis, playing diverse roles in embryonic and adult viability. To examine the role of the intrinsically disordered region (IDR) of Abl, researchers deleted the IDR in Drosophila. They found that Abl lacking the IDR was not able to rescue the roles of Abl in viability and embryonic morphogenesis. The IDR was also essential for cell shape changes and cytoskeletal regulation during embryonic morphogenesis and, surprisingly, for modulating protein stability..."

Accessing Streamflow Data via the Worldwide Web
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

This is a computer-based activity in which students retrieve data from websites maintained by the US Geological Survey (USGS) and the National Weather Service (NWS), and then use that data to test different hypotheses regarding streamflow and precipitation. Students import data from web sites into a spreadsheet program where they can construct scatter plots and perform simple statistical tests. The activity has two components, the first focusing on relations between streamflow and drainage basin characteristics (drainage area, slope, precipitation), the second focusing on trends in annual precipitation at two locations in the USA: Burlington, VT, and Boulder, CO. As part of the second component, students conduct a statistical test to determine if the long-term trends in precipitation are significant.

Acidic Oceans Prompt Evolution

0.0 stars

It's no secret that greenhouse gases warm the planet and that this has dire consequences for the environment whole islands swallowed up by rising seas, animal and plant species stressed by higher temperatures, and upsets in ecological interactions as populations move to cooler areas. However, carbon dioxide has another, less familiar environmental repercussion: making the Earth's oceans more acidic. Higher levels of carbon dioxide in the atmosphere mean that more carbon dioxide dissolves in the ocean. This dissolved carbon dioxide forms carbonic acid the same substance that helps give carbonated beverages their acidic kick. While this process isn't going to make the ocean fizzy anytime soon, it is introducing its own set of challenges for marine organisms like plankton and coral.

"Actinobacteria are some of the most widely distributed bacteria in soils and are well known for their ability to degrade plant residues in pure culture in the laboratory. Yet, despite the importance of microbe-driven decomposition to carbon sequestration in terrestrial systems, their importance and specific activity across diverse environments in the field are unknown. Researchers recently evaluated the ecophysiological roles of Actinobacteria in rice straw residue decomposition in a series of field and microcosm experiments. They found that although Actinobacteria represented only 4.6% of the total bacterial abundance, they encoded 16% of the total carbohydrate-active enzymes (CAZymes) involved in the breakdown of carbohydrates. The researchers also found that Actinobacteria taxonomic and functional compositions were relatively stable during straw decomposition and that the importance of Actinobacteria in decomposition increased as soil fertility decreased..."

Action Plan for Impacting Your Sustainable Development Goal
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

Using the article "Stop Raising Awareness Already" by Cristiano and Neimand and a six-step template, students create a plan to show how they apply the knowledge learned throughout the term to make a broader impact. The students are asked to very narrowly choose a single action they want a group of stakeholders to take and develop a multiple-step plan to accomplish the action. The students are required to select and justify a targeted stakeholder, develop an action, identify a messenger that can influence their targeted stakeholder to take the action, develop a sticky message relating the "ask" to the goal of the campaign, and document their key assumptions imbedded in their action plan.

"Humans rely on microbial communities in both natural and applied settings. One such applied setting is wastewater treatment plants, which use microbial communities to remove pollutants. However, the stability of the taxonomic diversity in these settings is not well understood. To close this gap, researchers examined how the microbial community in activated sludge changed over time in a full-scale wastewater treatment plant. For the first 3 years of a 9-year series, the microbial community fluctuated around a stable average. Then a bleaching event, marked in red under the timeline, abruptly pushed the community to an alternative stable state, where the originally dominant Actinobacteriota were disproportionally depleted and replaced with Proteobacteria, but these taxonomic changes led to little change in either the metabolic profile of the community or system performance. In a fine-scale analysis of dynamics, the researchers identified cohorts that dominated at different periods..."
