"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 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..."

Review
The goal of this lesson is to introduce students who are interested in human biology and biochemistry to the subtleties of energy metabolism (typically not presented in standard biology and biochemistry textbooks) through the lens of ATP as the primary energy currency of the cell. Avoiding the details of the major pathways of energy production (such as glycolysis, the citric acid cycle, and oxidative phosphorylation), this lesson is focused exclusively on ATP, which is truly the fuel of life. Starting with the discovery and history of ATP, this lesson will walk the students through 8 segments (outlined below) interspersed by 7 in-class challenge questions and activities, to the final step of ATP production by the ATP synthase, an amazing molecular machine. A basic understanding of the components and subcellular organization (e.g. organelles, membranes, etc.) and chemical foundation (e.g. biomolecules, chemical equilibrium, biochemical energetics, etc.) of a eukaryotic cell is a desired prerequisite, but it is not a must. Through interactive in-class activities, this lesson is designed to spark the students’ interest in biochemistry and human biology as a whole, but could serve as an introductory lesson to teaching advanced concepts of metabolism and bioenergetics in high school depending on the local science curriculum. No supplies or materials are needed.
In this seminar you will read closely and analyze the structure of ATP- Adenosine Triphosphate. You will curate your own information about the importance of ATP in a cell by listening and reading text as to what the experts have to say. By modeling the function of ATP in an inquiry lab you can accurately identify the various levels of cellular work done by Adenosine Triphosphate.StandardsBIO.A.3.1.1 Describe the fundamental roles of plastids (e.g., chloroplasts) and mitochondria in energy transformations.BIO.A.3.2.1 Compare and contrast the basic transformation of energy during photosynthesis and cellular respiration.BIO.A.3.2.2 Describe the role of ATP in biochemical reactions

"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..."

The Bee Cause Project connects bees and their keepers with communities and classrooms in order to share the life-giving lessons of our humble friends, the bees. Our shared habitat is in trouble, and bees have the tools to help us make a world fit for people and pollinators. For students of all ages, a look into a hive can revolutionize their understanding of our food system while working together towards a common goal. The Bee Cause Project delivers teaching tools to communities and classrooms so long looks into a hive turn into STEM exploration, career development, and the curiosity that fuels change. Join us in building the next generation of environmental stewards!
In this activity, students work with paleoclimate proxy data (d18O, CH4, CO2)from the Byrd and GISP2 ice cores to investigate millennial-scale climate changes during the Last Glacial/Deglacial time periods. Students must prepare a publication quality plot of the data and answer several questions about the similarities and differences between the time-series (north-south phasing, amplitude, symmetry) and use this information to assess the bipolar see-saw mechanism for abrupt climate changes. Students are encouraged to read two journal articles for more information and to synthesize their results with other information from lectures and earlier readings.

This document uses headings to allow students to begin the search with either the codon or the amino acid.
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.
