Definitive evidence for Club cells as progenitors for mutant Kras/Trp53-deficient lung cancer.

Int J Cancer 2021 Jul 31. Epub 2021 Jul 31.

Institute of Translational Immunology (TIM), University Medical Center, Johannes Gutenberg-University, Mainz, Germany.

Accumulating evidence suggests that both the nature of oncogenic lesions and the cell-of-origin can strongly influence cancer histopathology, tumor aggressiveness and response to therapy. However and although oncogenic Kras expression and loss of Trp53 tumor suppressor gene function have been demonstrated to initiate murine lung adenocarcinomas (LUADs) in alveolar type II (AT2) cells, clear evidence that Club cells, representing the second major subset of lung epithelial cells, can also act as cells-of-origin for LUAD is lacking. Equally, the exact anatomic location of Club cells that are susceptible to Kras transformation and the resulting tumor histotype remain to be established. Read More

Addressing Gender Inequities: Creation of a Multi-Institutional Consortium of Women Physicians in Academic Emergency Medicine.

Acad Emerg Med 2021 Jul 31. Epub 2021 Jul 31.

Department of Emergency Medicine, Harvard Medical School, USA.

Gender inequity is pervasive in medicine, including emergency medicine (EM), and is well documented in workforce representation, leadership, financial compensation, and resource allocation. The reasons for gender inequities in medicine, including academic EM, are multi-factorial and include disadvantageous institutional parental, family, and promotion policies, workplace environment and culture, implicit biases, and a paucity of women physician leader role models, mentors, and sponsors. To address some of the challenges of gender inequities and career advancement for women in academic EM, we established an innovative, peer-driven, multi-institutional consortium of women EM faculty employed at 4 distinct hospitals affiliated with one medical school.

From occupational to existential class: How to analyze class structure in hybrid societies (The case of Serbia).

Br J Sociol 2021 Jul 31. Epub 2021 Jul 31.

School of Social Sciences and Humanities, Loughborough University, Loughborough, UK.

In this article, we propose a model to analyze the class structure of hybrid post-socialist societies in South-East Europe (SEE), using the case of Serbia. We argue that, in such hybrid societies, social inequalities are generated by several mechanisms of similar strength: exploitative market mechanisms (based on economic capital) and different types of social closure mechanisms (based on political and social capital). Their influences are intertwined and cannot be analytically isolated or reduced to a common foundation. Read More

Optimal Control Strategies and Sensitivity Analysis of an HIV/AIDS-Resistant Model with Behavior Change.

Acta Biotheor 2021 Jul 30. Epub 2021 Jul 30.

School of Mathematics, Statistics and Computer Science, University of KwaZulu-Natal, Durban, South Africa.

Despite several research on HIV/AIDS, it is still incumbent to investigate more effective control measures to mitigate its infection level. Therefore, we introduce an HIV/AIDS-resistant model with behavior change and study its basic properties. In order to determine the most sensitive parameters that are responsible for disease transmission with respect to the basic reproduction number and those responsible for disease prevalence with respect to the endemic equilibrium, the sensitivity analysis was established and it was confirmed that the influx rate of people into the infected population and total abstinence from all risk practices and endemic areas are some of the most sensitive parameters for disease spread and disease eradication, respectively.

Synergistic melanoma cell death mediated by inhibition of both MCL1 and BCL2 in high-risk tumors driven by NF1/PTEN loss.

Oncogene 2021 Jul 30. Epub 2021 Jul 30.

Department of Pediatric Oncology, Dana-Farber Cancer Institute, Harvard Medical School, Boston, MA, USA.

Melanomas driven by loss of the NF1 tumor suppressor have a high risk of treatment failure and effective therapies have not been developed. Here we show that loss-of-function mutations of nf1 and pten result in aggressive melanomas in zebrafish, representing the first animal model of NF1-mutant melanomas harboring PTEN loss. MEK or PI3K inhibitors show little activity when given alone due to cross-talk between the pathways, and high toxicity when given together. Read More

Longitudinal analysis of human pancreatic adenocarcinoma development reveals transient gene expression signatures.

Mol Cancer Res 2021 Jul 30. Epub 2021 Jul 30.

Cell and Developmental Biology, University of Pennsylvania.

Previous transcriptome studies of human pancreatic ductal adenocarcinoma (PDAC) compare non-cancerous pancreatic intraepithelial neoplasias (PanINs) with late-stage PDAC obtained from different patients, thus have limited ability to discern network dynamics that contribute to the disease progression. We demonstrated previously that the 10-22 cell line, an induced pluripotent stem cell (iPS)-like line reprogrammed from late-stage human PDAC cells, recapitulated the progression from PanNs to PDAC upon transplantation into NOD/LtSz-scid/IL2R-gammanull mice. Herein, we investigated the transition from precursor to PDAC using the isogenic model. Read More
