Scores of academics have raised concerns about the equity of the online version of the test, arguing it disadvantages prospective students from rural and low-income backgrounds. “If I were … a student trying to take this exam, satisfying [the online testing] criteria would be extremely difficult for me,” says Emily Levesque, an assistant professor of astronomy at the University of Washington, Seattle.
Foundations that fund biomedical research in the United States, the United Kingdom, and elsewhere are reporting record revenue drops because of the pandemic. One major factor: It has forced them to cancel key fundraising events, including glitzy galas, sponsored walks, Broadway partnerships, and more.
Scientists identified a negative feedback loop comprising hepatic endoplasmic reticulum (ER) stress and micro RNA (miRNA)‐26a in nonalcoholic fatty liver disease pathogenesis. Combining miRNA dot blot array and quantitative PCR, they found that miR‐26a was specifically induced by ER stress in liver cells.

The authors focus on the current studies of the MDM2–p53 axis in hepatocellular carcinoma, and specifically discuss the impact of MDM2–p53 axis dysfunction by viral infection and metabolic disease in the transformation of normal hepatocytes into hepatoma cells.

Treatment with either of two bone morphogenetic protein (BMP) inhibitors reduced hepatic triglyceride content in diabetic mice. BMP inhibitor-induced decrease in hepatic triglyceride levels was associated with decreased mRNA encoding Dgat2, an enzyme integral to triglyceride synthesis.

Mutation of the hepatocyte nuclear factor (HNF)-1 binding site significantly decreased the promoter activity in hepatocytes, and the promoter carrying the mutated HNF-1 site was not transactivated by co-transfection of HNF-1 in a non-hepatic cell line.

Researchers found fibroblast growth factor receptor 4 (FGFR4) was overexpressed in hepatocellular carcinoma cell lines HepG2 and Hep3B. They used PD173074, an FGFR4 inhibitor, to explore the role of FGFR4 and its underlying mechanism in these cell lines.

Virtual lab tours are not new, but they have never been as common as in-person lab tours. However, the pandemic has generated strong incentives for formerly in-person lab tours to go online.
With a proclamation issued on Monday, US President Donald Trump extended and expanded immigration restrictions to limit the entry of foreign workers to the United States. The move set off ripples of alarm among scientists and drew fire from experts concerned about the future of US science.
Using a syngeneic hepatoceullar carcinoma (HCC) mouse model, the authors demonstrated that treatment with apatinib resulted in attenuation of tumor growth and increased tumor vessel normalization. Results indicated that NK cells, but not CD4+ or CD8+ T cells mediated the therapeutic efficacy of apatinib in HCC mouse models.
