Aberrant cytoplasmic accumulation of retinoblastoma protein in basal cells may lead to increased survival in malignant canine mammary tumours

open access: yesVeterinární Medicína, 2014
The retinoblastoma susceptibility gene RB-1 is a tumour suppressor gene that encodes a protein (Rb) that regulates the transition from the G1 phase to the S phase of the cell cycle. Inactivation of the Rb gene has been shown in a variety of human tumours,

Crosstalk Between Parkinson's Disease and Colorectal Cancer: Genetic Mechanisms, Gut Microbiota, and Therapeutic Insights

open access: yesHealth Care Science, EarlyView.
This review elucidates the crosstalk between Parkinson's disease and colorectal cancer, driven by shared genetics (PRKN, PINK1, DJ‐1) involving oxidative stress, cell cycle regulation, and inflammation. It identifies the gut microbiota—via functional amyloids and short‐chain fatty acids (SCFAs)—as a mechanistic bridge, offering insights for dual ...

Maximal COX-2 and ppRb expression in neurons occurs during early Braak stages prior to the maximal activation of astrocytes and microglia in Alzheimer's disease

open access: yesJournal of Neuroinflammation, 2005
Neuronal expression of cyclooxygenase-2 (COX-2) and cell cycle proteins is suggested to contribute to neurodegeneration during Alzheimer's disease (AD). The stimulus that induces COX-2 and cell cycle protein expression in AD is still elusive.

Epigenetic Dysregulation of Somatostatin Receptors (SSTR) 1–5 and Therapeutic Implications in Neuroendocrine and Non‐Neuroendocrine Malignancies

open access: yesInternational Journal of Cancer, EarlyView.
ABSTRACT Somatostatin receptors (SSTR) mediate the antiproliferative, antisecretory, and proapoptotic effects of somatostatin and its synthetic analogs. Their surface expression on neuroendocrine tumor (NET) cells is required for somatostatin analog therapy and radiopharmaceutical therapy (RPT).

Immunolocalization of the retinoblastoma protein in the human eye and in retinoblastoma.

open access: yesInvestigative ophthalmology & visual science, 1994
To determine whether, by employing recent advances in immunocytochemical technique, it is possible to identify reliably the product of the retinoblastoma (RB) susceptibility gene, p110RB1, in formalin-fixed, paraffin-embedded eyes with commercially available primary antibodies.

p16 Overexpression and Human Papillomavirus Positivity in More Than 1000 Penile Cancers

open access: yesInternational Journal of Cancer, EarlyView.
ABSTRACT Penile cancer is a severe disease, and a large proportion is related to high‐risk (hr) human papillomavirus (HPV). P16 is used as an immunohistochemical marker of HPV in clinical diagnostics. Population‐based data on the prevalence of p16 in penile cancer is scarce.

Specific Enzymatic Dephosphorylation of the Retinoblastoma Protein [PDF]

open access: yesMolecular and Cellular Biology, 1993
The retinoblastoma gene product (RB) undergoes cell cycle-dependent phosphorylation and dephosphorylation. Pulse-chase experiments revealed that the change in RB gel electrophoretic migration which occurs near mitosis is due to enzymatic dephosphorylation (J. W. Ludlow, J. Shon, J. M. Pipas, D. M. Livingston, and J. A. DeCaprio, Cell 60:387-396, 1990).

Inhibition of retinoblastoma mRNA degradation through Poly (A) involved in the neuroprotective effect of berberine against cerebral ischemia. [PDF]

open access: yesPLoS ONE, 2014
Berberine is one kind of isoquinoline alkaloid with anti-apoptotic effects on the neurons suffering ischemia. To address the explanation for these activities, the berberine-induced cell cycle arrest during neurons suffering ischemia/reperfusion had been ...

The T‐Cell Response Mechanism in Human Papillomavirus‐Associated Cervical Cancer and New Strategies for Immunotherapy

open access: yesiNew Medicine, EarlyView.
ABSTRACT Human papillomavirus (HPV) is a double‐stranded DNA virus that infects human skin and mucosal tissues exclusively. The German scientist Harald zur Hausen was awarded the 2008 Nobel Prize in Physiology or Medicine for his discovery of the link between HPV infection and cervical cancer.

Tetraspanin protein KAI1 expression in retinoblastoma [PDF]

open access: yesBritish Journal of Ophthalmology, 2004
KAI1/CD82 is a metastasis suppressor gene located on human chromosome 11p11.2. It is a member of the structurally distinct family of cell surface glycoprotein, transmembrane 4-protein superfamily.1 KAI1 was initially isolated as a gene that suppressed metastasis of rat prostate tumour cells.2 KAI1 is downregulated in several types of human malignancies.
