Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

open access: yesMolecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

A stem cell proliferation burst forms new layers of P63 expressing suprabasal cells during zebrafish postembryonic epidermal development

open access: yesBiology Open, 2013
Summary Organ growth during development is a highly regulated process with both temporal and spatial constraints. Epidermal stratification is essential for skin growth and development.

Transformation of Epidermal Cells in Culture

open access: yesJournal of Investigative Dermatology, 1983
Studies performed on mouse skin have indicated that chemical carcinogenesis can be subdivided into two distinct stages, initiation and promotion. Initiation results from exposure to a classical mutagenic carcinogen and is irreversible even after a single exposure.

Weakening the nuclear envelope: Lamin B receptor in melanoma metastasis

open access: yesMolecular Oncology, EarlyView.
LBR‐driven nuclear fragility supports melanoma invasion. A: Melanocyte presents low LBR (Lamin B Receptor) levels, maintaining nuclear integrity and lamina‐chromatin tethering. B: During malignant progression, upregulation of LBR clusters at the INM (Inner Nuclear Membrane) during confined migration causes local lamina weakening and cholesterol ...

The development of stomata and other epidermal cells on the rice leaves

open access: yes, 2012
In the leaves of rice (Oryza sativa), stomatal initials arose from two asymmetric cell divisions and a symmetric division. Guard mother cells (GMCs) and long cells in stomatal files (LCSs) were formed through the first asymmetric division of the ...

Epigenetic heterogeneity and plasticity in therapy‐induced tumor states through single‐cell multi‐omics

open access: yesMolecular Oncology, EarlyView.
Single‐cell multi‐omics reveals epigenetic heterogeneity across therapy‐adaptive tumor states, including quiescent/dormant, drug‐tolerant persister, and EMT‐like phenotypes. By linking regulatory features with state‐associated biomarkers, these approaches inform biomarker‐guided therapeutic strategies for evolving tumors.

Histology of Alarm Substance Cells in Relation to Parasite Load and Fish Size for Hornyhead Chub (Nocomis biguttatus)

open access: yes, 2012
Color poster with text, images, diagrams, tables, and graphs.It is generally thought that alarm substance cells (ASC) found in fish epidermis evolved as a means of reducing predation risk via the release of a chemical substance these cells hold.

CD36+-Dendritic Epidermal Cells: A Putative Actor in the Cutaneous Immune System

open access: yesCell Transplantation, 1994
In the present study we have investigated by indirect immunofluorescence staining and mixed lymphocyte reaction methods, the localization, distribution, percentage, and the immunological involvement of CD36+- dendritic epidermal cells (CD36+-DECs) in ...

PAK1 activation drives divergent resistance mechanisms to aromatase inhibition and tamoxifen in a luminal: A breast cancer model

open access: yesMolecular Oncology, EarlyView.
Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

Matrix metalloproteinase‐9 regulates cell adhesion and membrane protrusive activity of ovarian cancer cells

open access: yesFEBS Open Bio, EarlyView.
Matrix metalloproteinase‐9 (MMP9) drives ovarian cancer progression. Using MMP9‐null cells (M9‐KO) created from ovarian cancer cells, we found MMP9 loss did not block Epidermal Growth Factor (EGF)‐driven E‐cadherin dissolution or EMT but delayed and reduced EGF‐driven membrane protrusions. Transient MMP9 re‐expression drove membrane protrusion.
