Mystery of roe deer embryonic diapause revealed

Everyone is familiar with the roe deer, either from crossword puzzles or from real-life encounters during a jog or a hike in the forest: majestic creatures with elegant big black eyes.

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 discovers lagging chromosomes as one of the major causes of infertility

Why do women over 35 have more difficulty getting pregnant? After discovering one of the causes of age-related female infertility, researchers at the University of Montreal Hospital Research Centre suggest that it will be possible in the future to improve the quality of the eggs of older patients by intervening on the cell cycle level.

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.

Researchers discover how PARP inhibitors selectively kill BRCA-mutant cancer cells

A team of Massachusetts General Hospital researchers has discovered how an important class of anti-cancer drugs called PARP inhibitors works, a finding that could help improve treatment and prolong survival for patients with breast cancer and other malignancies.

Understanding hypoxia-induced gene expression variations in aggressive type of pancreatic cancer

Cancer cells have evolved a myriad of mechanisms that support their uncontrolled growth. In case of solid tissue tumors, the tumor microenvironment, which consists of extracellular components and conditions surrounding the tumor, is crucial in deciding the fate of the cancer cells.

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.

Study offers genetic insights into the underlying biology of reproductive aging

The age at which women go through menopause is critical for fertility and impacts healthy ageing in women, but reproductive ageing has been difficult for scientists to study and insights into the underlying biology are limited.

Scientists identify new therapeutic target for several aggressive cancers

A protein in tumor cells could be targeted to treat some types of aggressive cancer including brain, blood, skin, and kidney, new research has shown.

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.

Oncotarget data reveals retinoic acid as fundamental regulator of cell cycle and differentiation

Oncotarget published "Role for Fgr and Numb in retinoic acid-induced differentiation and G0 arrest of non-APL AML cells" which reported that retinoic acid is a fundamental regulator of cell cycle and cell differentiation.

Scientists identify key role of p38-MK2 pathway in determining cell fate in response to stress

Living organisms are often exposed to stress stimuli generated either by external or internal factors, and they need to respond accordingly.

Researchers study the role of subnuclear NSrp70 in T cell-mediated adaptive immunity

T cells are components of the body’s immune system. The ability of T cells to recognize diverse pathogens and mount a defense against them stems from the way proteins are spliced during their development and maturation.

Study unravels the link between chromosomal instability and cellular senescence

Chromosomal instability is a feature of solid tumours such as carcinoma. Likewise, cellular senescence is a process that is highly related to cellular ageing and its link to cancer is becoming increasingly clear. Scientists led by ICREA researcher Dr. Marco Milán at IRB Barcelona have revealed the link between chromosomal instability and cellular senescence.

Researchers develop the world's first digital cancer cell model

The computer model, developed under the lead management of researchers at TU Graz, simulates the cyclical changes in the membrane potential of a cancer cell using the example of human lung adenocarcinoma and opens up completely new avenues in cancer research.

Reactive oxygen species are important components in cancer treatments

Reactive oxygen species (ROS) are highly reactive chemicals which contain oxygen radicals. Hypochlorous acid, peroxides, superoxide, singlet oxygen, alpha-oxygen and hydroxyl radicals are the major examples of ROS, which are familiar to persons from many walks of life as they are used in many domestic and industrial processes.

How does dexamethasone therapy work in severe COVID-19?

The possible mechanisms that result in dexamethasone being an effective drug against severe SARS-CoV-2 infection are investigated in a new study. The paper’s authors advance the hypothesis that SARS-CoV-2 infection induces cell-specific insensitivity to glucocorticoids, possibly as an unintentional result of the viral replication cycle.

Understanding new resting phase of stem cells could help put glioma tumors to sleep

Christopher Plaisier, an assistant professor of biomedical engineering in the Ira A. Fulton Schools of Engineering at Arizona State University, and Samantha O'Connor, a biomedical engineering doctoral student in the Plaisier Lab, are leading research into a new stage of the stem cell life cycle that could be the key to unlocking new methods of brain cancer treatment.
