Study uncovers epigenetic mechanisms that promote glioma tumor growth

Northwestern Medicine investigators have discovered the epigenetic mechanisms involved in the regulation of multiple oncogenes in glioma cells, mechanisms that promote overall glioma tumor growth and resistance to therapy, according to a study published in the journal Clinical Cancer Research.

Pericentromeric noncoding RNA provokes inflammatory gene expression in senescence and cancer

Research from the Cancer Institute at the Japanese Foundation for Cancer Research (JFCR), which was published today (August 23, at 3 pm US ET) in the leading international scientific journal Proceedings of the National Academy of Sciences of the United States of America, reveals that noncoding RNA derived from pericentromeric repetitive sequences provokes inflammatory gene expression in senescence and cancer.

Study investigates the effects of calycosin on breast cancer cell progression

Aging-US published "Calycosin inhibits breast cancer cell migration and invasion by suppressing EMT via BATF/TGF-β1" which reported that in this study, the authors investigated the effects of calycosin on breast cancer cell progression and their underlying mechanisms. Calycosin dose- and time-dependently inhibited proliferation, migration, and invasion by T47D and MCF-7 breast cancer cells by downregulating basic leucine zipper ATF-like transcription factor expression.

SMC protein complex plays a decisive role in the dynamics of holocentromeres

Monocentromeres are typical for the chromosomes of most animals and plants. The centromere is necessary for the transport of the chromosomes and represents the connection point between the chromatids.

Researchers develop the most comprehensive molecular map of lung squamous cell carcinoma

Lung cancer remains the leading cause of cancer-associated death in the United States and worldwide. Patients with a subtype called lung adenocarcinoma (LUAD) have benefited from the development of new targeted medicines, but the search for effective new therapies for another subtype called lung squamous cell carcinoma (LSCC) has largely come up short.

UAB researchers identify potential therapeutic target for ovarian cancer

A gene called DOT1L appears to play a role in progression and severity of ovarian cancer, and inhibitors of the DOT1L enzyme may offer a new therapeutic approach for the disease, University of Alabama at Birmingham researchers say in a study published in the journal Oncogenesis.

UVA researchers overturn conventional wisdom on action of key hormone receptors within cells

Researchers at the University of Virginia School of Medicine have overturned conventional wisdom on the workings of vital hormone receptors within cells, a finding that could boost drug development for diabetes and related metabolic disorders, cancer and other diseases.

New insights on replication-stress sensitivity in breast cancer cells

Oncotarget published "Frame-shift mediated reduction of gain-of-function p53 R273H and deletion of the R273H C-terminus in breast cancer cells result in replication-stress sensitivity" which reported that these authors recently documented that gain-of-function mutant p53 R273H in triple negative breast cancer cells interacts with replicating DNA and PARP1.

SARS-CoV-2 reprograms host chromatic network to induce immune dysfunction

A recent study conducted at the University of Texas Science Center, Houston, in the USA, has revealed that upon infection, SARS-CoV-2 alters the host chromatin architecture to suppress antiviral interferon-responsive genes and augment inflammatory genes. The study is currently available on the bioRxiv* preprint server.

Researchers discover new set of signals that control production of goblet cells in the lung

Proper lung function relies on the precise balance of specialized epithelial cells (cells that line the surfaces of the body) that coordinate functions to maintain homeostasis.

NYUAD researchers unlock an epigenetic code that allows liver regeneration

NYU Abu Dhabi researchers uncovered a code that sets the genome of the liver to account for the remarkable ability for this organ to regenerate.

Researchers unravel new mechanism that enables cancer development

Researchers at the University of North Carolina at Chapel Hill and the UNC Lineberger Comprehensive Cancer Center have uncovered a new mechanism that activates specific genes, leading to the development of cancers.

Researchers develop new therapeutic approach for treating acute myeloid leukemia

Leukemia stem cells are rare cells that can renew themselves while continuing to generate malignant cells known as leukemic blasts. These cells are difficult to eradicate using chemotherapy drugs and frequently lead to recurrence of leukemia.

Study uncovers new mechanisms underlying lineage plasticity

Cancer cells have an uncanny ability to evolve and adapt to overcome the treatments used against them. While patient survival has been extended by modern drugs that block the production or action of male hormones that fuel prostate cancer -- androgen receptor inhibitors such as enzalutamide, apalutamide, darolutamide, and abiraterone -- eventually these drugs stop working.

Chan Zuckerberg Initiative announces nearly $28 million for visual proteomics

Today, the Chan Zuckerberg Initiative (CZI) announced nearly $28 million in grants to support technology developments that will allow researchers to see the inner workings of cells at near-atomic resolution through next-generation electron microscopy.

Rapamycin targets gut cells to alter the way DNA is stored

Our genetic material is stored in our cells in a specific way to make the meter-long DNA molecule fit into the tiny cell nucleus of each body cell.

Study offers longitudinal roadmap of immune activation and resolution in mild COVID-19

Researchers from the US recently profiled the longitudinal immune response in mild COVID-19 patients starting with early time points of 1-15 days post-infection through convalescence to over 100 days after onset of symptoms.

Reusing old vaccines to boost innate immunity against COVID-19

The COVID-19 vaccine is currently the best form of protection against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its variants. But a new perspective article published in the journal PNAS suggests it’s not the panacea to stopping SARS-CoV-2.

DFG establishes new collaborative research centers to promote world-class research at universities

The Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) is establishing eleven new Collaborative Research Centers (CRC) to promote world-class research at universities. This was announced by the relevant Grants Committee, which met by video conference due to the coronavirus pandemic.
