Tmem119 expression is downregulated in a subset of brain metastasis-associated microglia

BMC Neuroscience
Under pathological conditions, the immune-specialized brain microenvironment contains both resident microglia and bone marrow-derived myeloid cells recruited from peripheral circulation.

Liver organoids: modelling complexity in homeostasis and disease

FEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

IRE1α‐XBP1s axis regulates SREBP1‐dependent MRP1 expression to promote chemoresistance in non‐small cell lung cancer cells

Thoracic Cancer
Background Inositol‐requiring enzyme 1 (IRE1) is an endoplasmic reticulum (ER)‐resident transmembrane protein that senses ER stress and mediates an essential arm of the unfolded protein response (UPR).

Kindlin-2 mediates mechanotransduction in bone by regulating expression of Sclerostin in osteocytes

Communications Biology, 2021
Qin et al. show the involvement of Kindlin-2 in osteocyte mechanotransduction. They show Kindlin-2 mediates skeletal responses to mechanical stimulation through Smad 2/3 mediated inhibition of Sclerostin.

The microbiome in human skin aging

FEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

FEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

CXCR4, CXCR7 and PBRM1 are responsible for everolimus and cabozantinib resistance in human renal cancer cells

Cell Death Discovery
The mTOR inhibitor everolimus (RAD001), previously used in first-line treatment of metastatic renal cancer (mRCC), is currently reserved for the following lines of therapy. However, many patients eventually develop resistance to RAD001. To shed new light

Emerging experimental and computational methods for studying redox‐regulated structural transitions

FEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Imaging angiogenesis and the microenvironment [PDF]

APMIS, 2008
Intravital microscopy has provided unprecedented insights into tumor pathophysiology, including angiogenesis and the microenvironment. Tumor vasculature shows an abnormal organization, structure, and function. Tumor vessels are leaky, blood flow is heterogeneous and often compromised.

The heterodimeric amino acid transporters (HAT) of the SLC7/SLC3 family: A structure−function relationships and relevance to human pathology

FEBS Letters, EarlyView.
Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.
