Escape from TGF‐β‐induced senescence promotes aggressive hallmarks in epithelial hepatocellular carcinoma cells

open access: yesMolecular Oncology, EarlyView.
Chronic TGF‐β exposure drives epithelial HCC cells from a senescent state to a TGF‐β resistant mesenchymal phenotype. This transition is characterized by the loss of Smad3‐mediated signaling, escape from senescence, enhanced invasiveness and metastatic potential, and upregulation of key resistance modulators such as MARK1 and GRM8, ultimately promoting

UV micro-irradiation of the Chinese hamster cell nucleus and caffeine post-treatment immunocytochemical localization of DNA photolesions in cells with partial and generalized chromosome shattering [PDF]

open access: yes, 1983
UV micro-irradiation of a small part of the Chinese hamster nucleus and caffeine post-incubation often results in shattered chromosomes at the first post-irradiation mitosis.

ShcD adaptor protein drives invasion of triple negative breast cancer cells by aberrant activation of EGFR signaling

open access: yesMolecular Oncology, EarlyView.
We identified adaptor protein ShcD as upregulated in triple‐negative breast cancer and found its expression to be correlated with reduced patient survival and increased invasion in cell models. Using a proteomic screen, we identified novel ShcD binding partners involved in EGFR signaling pathways.

Immune deposits in cutaneous lesions of Wegener′s granulomatosis: Predictor of an active disease

open access: yesIndian Journal of Dermatology, 2011
A retrospective analysis was conducted of eight cases of Wegener′s granulomatosis (WG), who presented with cutaneous lesions. The clinical, immunopathologic and histopathologic features of the cutaneous lesions were reviewed.

Aberrant expression of nuclear prothymosin α contributes to epithelial‐mesenchymal transition in lung cancer

open access: yesMolecular Oncology, EarlyView.
Nuclear prothymosin α inhibits epithelial‐mesenchymal transition (EMT) in lung cancer by increasing Smad7 acetylation and competing with Smad2 for binding to SNAI1, TWIST1, and ZEB1 promoters. In early‐stage cancer, ProT suppresses TGF‐β‐induced EMT, while its loss in the nucleus in late‐stage cancer leads to enhanced EMT and poor prognosis.

Direct Immunofluorescence In Lichen Planus

open access: yesIndian Journal of Dermatology, 1996
Eighteen patients with lesions suggestive of lichen planus (LP) were blopsied for histopathological examination and direct immunofluorescence (IMF) by standard techniques. All the 18 patients showed features of LP on histopathological examination.

Direct immunofluorescent findings in scleroderma syndromes

open access: yesActa Dermato-Venereologica, 1981
Cutaneous direct immunofluorescent findings were examined in 78 patients who had either vascular scleroderma (group 1, 52 patients) or scleroderma with features of myositis or lupus erythematosus (group 2, 26 patients). Group 2 had higher antinuclear antibody levels, erythrocyte sedimentation rates, serum IgG concentrations, frequency of positive LE ...

Loss of proton‐sensing GPR4 reduces tumor progression in mouse models of colon cancer

open access: yesMolecular Oncology, EarlyView.
G protein‐coupled receptor 4 (GPR4) is a pH‐sensing receptor activated by acidic pH. GPR4 expression is increased in patients with inflammatory bowel disease who are at high risk of developing colorectal cancer. In mouse models, loss of GPR4 attenuated tumor progression. This correlated with increased IL2 and natural killer cell activity.

Immunofluorescence profile of discoid lupus erythematosus

open access: yesIndian Journal of Pathology and Microbiology, 2015
The direct immunofluorescence (DIF) of skin in conjunction with histopathology gives the best diagnostic yield. It is invaluable in confirming the diagnosis of small vessel vasculitides and bullous lesions of the skin and can be used as an additional ...

Reactivation of the mitosis-promoting factor in postmitotic cardiomyocytes [PDF]

open access: yes, 2003
Cardiomyocytes cease to divide shortly after birth and an irreversible cell cycle arrest is evident accompanied by the downregulation of cyclin-dependent kinase activities.
