A Comparison of Polyvalent Passive Immunoprotection from Antibodies with Different Immunity Models of Live or Inactivated Vibrio fluvialis in Fish

Fishes
Polyvalent passive vaccines can act fast in resisting various bacteria with good efficacy, and they have application value in aquaculture. This study prepared live and inactivated Vibrio fluvialis mouse antisera (L-VF-antiserum and I-VF-antiserum), and ...

Developmental potential of aneuploid human embryos cultured beyond implantation

Nature Communications, 2020
Aneuploidy, abnormal chromosome number, is a major cause of early pregnancy loss. Here the authors determine the extent of post-implantation development of human embryos with common aneuploidies in culture, finding developmental arrest of monosomy 21 ...

Recurrent cancer‐associated ERBB4 mutations are transforming and confer resistance to targeted therapies

Molecular Oncology, EarlyView.
We show that the majority of the 18 analyzed recurrent cancer‐associated ERBB4 mutations are transforming. The most potent mutations are activating, co‐operate with other ERBB receptors, and are sensitive to pan‐ERBB inhibitors. Activating ERBB4 mutations also promote therapy resistance in EGFR‐mutant lung cancer.

Co-Exposure of Microplastics and Avermectin at Environmental-Related Concentrations Caused Severe Heart Damage Through ROS-Mediated MAPK Signaling in Larval and Adult Zebrafish

Toxics
The widespread presence of polystyrene microplastics (PS-MPs) and agricultural pollutants such as avermectin (AVM) in aquatic environments poses a significant threat to aquatic organisms.

Root Development: The Embryo Within? [PDF]

Current Biology, 2004
Root growth is sustained by stem cells maintained at the root tip. Recent evidence suggests that genes required to maintain root stem cells also specify root identity in the early embryo.

Dammarenediol II enhances etoposide‐induced apoptosis by targeting O‐GlcNAc transferase and Akt/GSK3β/mTOR signaling in liver cancer

Molecular Oncology, EarlyView.
Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...

Targeting p38α in cancer: challenges, opportunities, and emerging strategies

Molecular Oncology, EarlyView.
p38α normally regulates cellular stress responses and homeostasis and suppresses malignant transformation. In cancer, however, p38α is co‐opted to drive context‐dependent proliferation and dissemination. p38α also supports key functions in cells of the tumor microenvironment, including fibroblasts, myeloid cells, and T lymphocytes.

Distribution of human-pathogenic Cryptosporidium spp., Giardia duodenalis, and Enterocytozoon bieneusi in crab-eating macaques in China

Frontiers in Microbiology
IntroductionThe positive rates and genetic identity of Cryptosporidium spp., Giardia duodenalis (G. duodenalis), and Enterocytozoon bieneusi (E. bieneusi) were unclear in crab-eating macaques in Suzhou and Beijing, China.MethodsA total of 504 fecal ...

Overview of molecular signatures of senescence and associated resources: pros and cons

FEBS Open Bio, EarlyView.
Cells can enter a stress response state termed cellular senescence that is involved in various diseases and aging. Detecting these cells is challenging due to the lack of universal biomarkers. This review presents the current state of senescence identification, from biomarkers to molecular signatures, compares tools and approaches, and highlights ...

Embryo development in dairy cattle

Theriogenology, 2016
During the past 50 years, the fertility of high-producing lactating dairy cows has decreased, associated with intensive selection for increased milk production. The physiological and metabolic changes associated with high milk production, including decreased (glucose, insulin, IGF-I) or increased (nonesterified fatty acids, ketone bodies ...
