HIV-1 expression induces cyclin D1 expression and pRb phosphorylation in infected podocytes: cell-cycle mechanisms contributing to the proliferative phenotype in HIV-associated nephropathy

open access: yesBMC Microbiology, 2002
Background The aberrant cell-cycle progression of HIV-1-infected kidney cells plays a major role in the pathogenesis of HIV-associated nephropathy, however the mechanisms whereby HIV-1 induces infected glomerular podocytes or infected tubular epithelium ...

Caenorhabditis elegans cyclin D/CDK4 and cyclin E/CDK2 induce distinct cell cycle re-entry programs in differentiated muscle cells. [PDF]

open access: yesPLoS Genetics, 2011
Cell proliferation and differentiation are regulated in a highly coordinated and inverse manner during development and tissue homeostasis. Terminal differentiation usually coincides with cell cycle exit and is thought to engage stable transcriptional ...

Changes in neuronal CycD/Cdk4 activity affect aging, neurodegeneration, and oxidative stress. [PDF]

open access: yes, 2015
Mitochondrial dysfunction has been implicated in human diseases, including cancer, and proposed to accelerate aging. The Drosophila Cyclin-dependent protein kinase complex cyclin D/cyclin-dependent kinase 4 (CycD/Cdk4) promotes cellular growth by ...

Cyclin D1 promotes neurogenesis in the developing spinal cord in a cell cycle-independent manner [PDF]

open access: yes, 2011
Neural stem and progenitor cells undergo an important transition from proliferation to differentiation in the G1 phase of the cell cycle. The mechanisms coordinating this transition are incompletely understood.

Thyroxine differentially modulates the peripheral clock: lessons from the human hair follicle [PDF]

open access: yes, 2015
The human hair follicle (HF) exhibits peripheral clock activity, with knock-down of clock genes (BMAL1 and PER1) prolonging active hair growth (anagen) and increasing pigmentation.

Subunit rearrangement of the cyclin-dependent kinases is associated with cellular transformation [PDF]

open access: yes, 1993
In normal human diploid fibroblasts, cyclins of the A, B, and D classes each associate with cyclin-dependent kinases (CDKs), proliferating cell nuclear antigen (PCNA), and p21, thereby forming multiple independent quaternary complexes.

Cyclin D3 Governs Clonal Expansion of Dark Zone Germinal Center B Cells

open access: yesCell Reports, 2020
Summary: Germinal center (GC) B cells surge in their proliferative capacity, which poses a direct risk for B cell malignancies. G1- to S-phase transition is dependent on the expression and stability of D-type cyclins.

Expression of D-type cyclins in differentiating cells of the mouse spinal cord

open access: yesGenetics and Molecular Biology, 2007
The D-type cyclins form complexes with the cyclin dependent (CD) kinases CDK4 and CDK6 and promote the G1-S phase transition of the cell cycle by antagonizing the retinoblastoma suppresser protein pRB. In the developing nervous system D-type cyclins show

Regulation of sonic hedgehog-GLI1 downstream target genes PTCH1, Cyclin D2, Plakoglobin, PAX6 and NKX2.2 and their epigenetic status in medulloblastoma and astrocytoma [PDF]

open access: yes, 2010
Background The Sonic hedgehog (Shh) signaling pathway is critical for cell growth and differentiation. Impairment of this pathway can result in both birth defects and cancer.

New twist in the regulation of cyclin D1

open access: yesBiomolecular Concepts, 2010
Among the cell cycle-related mammalian cyclins, cyclin D1 is more closely connected with cell proliferation in response to extracellular signals than the cell cycle clock itself.
