Flowcytometric evaluation of cell cycle regulators (cyclins and cyclin dependent kinase inhibitors) expressed on bone marrow cells of patients with chronic myelogenous leukemia and multiple myeloma

open access: yesTurkish Journal of Hematology, 2012
OBJECTIVE: Etiopathology of malignancy can be demonstrated by the comparison of the quantified changes in the different phases of the cycle about cyclins and cyclin dependent kinase inhibitors (CDKI) in healthy and malignant proliferated cells.

Cyclins and the cyclin-kinase system, and their potential roles in nephrology [PDF]

open access: yesNephrology Dialysis Transplantation, 1998
Our understanding of the cell-cycle mechanisms has progressively advanced in the past few years. Cyclins and cyclin-dependent kinases play major roles as positive cell-cycle regulatory proteins and CDK inhibitors; while the Kip family and INK4 family are negative regulatory proteins in mesangial cells and renal tubular cells.

Detection rate for ESR1 mutations is higher in circulating‐tumor‐cell‐derived genomic DNA than in paired plasma cell‐free DNA samples as revealed by ddPCR

open access: yesMolecular Oncology, EarlyView.
Analysis of ESR1 mutations in plasma cell‐free DNA (cfDNA) is highly important for the selection of treatment in patients with breast cancer. Using multiplex‐ddPCR and identical blood draws, we investigated whether circulating tumor cells (CTCs) and cfDNA provide similar or complementary information for ESR1 mutations.

The key role of CYC2 during meiosis in Tetrahymena thermophila

open access: yesProtein & Cell, 2016
Meiotic recombination is carried out through a specialized pathway for the formation and repair of DNA double-strand breaks (DSBs) made by the Spo11 protein.

KMT2A degradation is observed in decitabine‐responsive acute lymphoblastic leukemia cells

open access: yesMolecular Oncology, EarlyView.
We demonstrate that decitabine (DEC) not only degrades the DNA methyltransferase DNMT1 but also the leukemic driver lysine methyltransferase KMT2A likely due to structural similarity of the DNA‐binding CXXC domains. DEC influences KMT2A downstream processes and synergizes with menin inhibitor revumenib (REV) to decrease leukemic cell proliferation, and

Single-cell RNA sequencing of shoot apex reveals the mechanism of cyclin regulating cell division via auxin signaling pathway in Populus alba

open access: yesFrontiers in Plant Science
The shoot apex of Populus alba primarily comprises the shoot apical meristem, axillary meristem, leaf primordium, and young leaves, all of which exhibit high division potential. The single-cell RNA sequencing of the apical buds of P.

Expression, regulation and activity of a B2-type cyclin in mitotic and endoreduplicating maize endosperm

open access: yesFrontiers in Plant Science, 2014
Cyclin-dependent kinases, the master regulators of the eukaryotic cell cycle, are complexes comprised of a catalytic serine/threonine protein kinase and an essential regulatory cyclin.

Etoposide‐induced cancer cell death: roles of mitochondrial VDAC1 and calpain, and resistance mechanisms

open access: yesMolecular Oncology, EarlyView.
The complex mode of action of the topoisomerase II inhibitor etoposide in triggering apoptosis involves several mechanisms: overexpression of the mitochondrial protein VDAC1, leading to its oligomerization and formation of a large channel that mediates the release of pro‐apoptotic protein; and overexpression of the apoptosis regulators p53, Bax, and ...

Missense MED12 variants in 22 males with intellectual disability: From nonspecific symptoms to complete syndromes

open access: yesAmerican Journal of Medical Genetics Part A, Volume 191, Issue 1, Page 135-143, January 2023., 2023
Abstract We describe the phenotype of 22 male patients (20 probands) carrying a hemizygous missense variant in MED12. The phenotypic spectrum is very broad ranging from nonspecific intellectual disability (ID) to the three well‐known syndromes: Opitz–Kaveggia syndrome, Lujan–Fryns syndrome, or Ohdo syndrome.

OpenMM 8: Molecular Dynamics Simulation with Machine Learning Potentials [PDF]

open access: yesarXiv, 2023
Machine learning plays an important and growing role in molecular simulation. The newest version of the OpenMM molecular dynamics toolkit introduces new features to support the use of machine learning potentials. Arbitrary PyTorch models can be added to a simulation and used to compute forces and energy.
