YTHDF2 promotes mitotic entry and is regulated by cell cycle mediators

Newsemia
by Qili Fei, Zhongyu Zou, Ian A. Roundtree, Hui-Lung Sun, Chuan He The N6-methyladenosine (m6A) modification regulates mRNA stability and translation. Here, we show that...

Eco-evolutionary significance of “loners”

Newsemia
by Fernando W. Rossine, Ricardo Martinez-Garcia, Allyson E. Sgro, Thomas Gregor, Corina E. Tarnita Loners—individuals out of sync with a coordinated majority—occur frequently in nature....

Evolutionary repair: Changes in multiple functional modules allow meiotic cohesin to support mitosis

Newsemia
by Yu-Ying Phoebe Hsieh, Vasso Makrantoni, Daniel Robertson, Adèle L. Marston, Andrew W. Murray The role of proteins often changes during evolution, but we do...

Simulations reveal challenges to artificial community selection and possible strategies for success

Newsemia
by Li Xie, Alex E. Yuan, Wenying Shou Multispecies microbial communities often display “community functions” arising from interactions of member species. Interactions are often difficult...

Cell aging preserves cellular immortality in the presence of lethal levels of damage

Newsemia
by Audrey Menegaz Proenca, Camilla Ulla Rang, Andrew Qiu, Chao Shi, Lin Chao Cellular aging, a progressive functional decline driven by damage accumulation, often culminates...

G1/S cell cycle regulators mediate effects of circadian dysregulation on tumor growth and provide targets for timed anticancer treatment

Newsemia
by Yool Lee, Nicholas F. Lahens, Shirley Zhang, Joseph Bedont, Jeffrey M. Field, Amita Sehgal Circadian disruption has multiple pathological consequences, but the underlying mechanisms...

HSP-4/BiP expression in secretory cells is regulated by a developmental program and not by the unfolded protein response

Newsemia
by Ji Zha, Mingjie Ying, Jasmine Alexander-Floyd, Tali Gidalevitz Differentiation of secretory cells leads to sharp increases in protein synthesis, challenging endoplasmic reticulum (ER) proteostasis....
Biology

Spontaneously slow-cycling subpopulations of human cells originate from activation of stress-response pathways

Newsemia
by Mingwei Min, Sabrina L. Spencer Slow-cycling subpopulations exist in bacteria, yeast, and mammalian systems. In the case of cancer, slow-cycling subpopulations have been proposed...
Biology

Mysteries in embryonic development: How can errors arise so frequently at the beginning of mammalian life?

Newsemia
by Isabell Schneider, Jan Ellenberg Chromosome segregation errors occur frequently during female meiosis but also in the first mitoses of mammalian preimplantation development. Such errors...
