Protein Mobility in the Cytoplasm of Escherichia coli [PDF]

, 1999
The rate of protein diffusion in bacterial cytoplasm may constrain a variety of cellular functions and limit the rates of many biochemical reactions in vivo. In this paper, we report noninvasive measurements of the apparent diffusion coefficient of green

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

FEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

The Role of Oocyte Organelles in Determining Developmental Competence

Biology, 2017
The ability of an oocyte to undergo successful cytoplasmic and nuclear maturation, fertilization and embryo development is referred to as the oocyte’s quality or developmental competence.

Gaucher’s Disease: A Rare Case, Diagnosed By Fine Needle Aspiration Cytology [PDF]

Journal of Clinical and Diagnostic Research, 2016
Fine Needle Aspiration (FNA) is a simple, inexpensive and innocuous diagnostic tool. It is increasingly accepted in daily medical practice. We report a case of Gaucher’s disease diagnosed by FNA of enlarged spleen in a seven-year-old male presented with

The Caenorhabditis elegans DPF‐3 and human DPP4 have tripeptidyl peptidase activity

FEBS Letters, EarlyView.
The dipeptidyl peptidase IV (DPPIV) family comprises serine proteases classically defined by their ability to remove dipeptides from the N‐termini of substrates, a feature that gave the family its name. Here, we report the discovery of a previously unrecognized tripeptidyl peptidase activity in DPPIV family members from two different species.

Sex-specific alterations in creatine metabolism in cellular compartments of peripheral blood leukocytes in type 1 diabetes

AIMS Bioengineering
The creatine (Cr)/creatine kinase (CK) system plays a crucial role in cellular energy metabolism, glucose control, and the immune response. This study aimed to investigate this system in the peripheral blood leukocytes (PBL) of Armenians with type 1 ...

Male sterility of triticale lines generated through recombination of triticale and rye maintainers

Spanish Journal of Agricultural Research, 2014
The Triticum timopheevi cytoplasmic male sterility (cms) system in triticale (xTriticosecale Wittmack) suffers from a low frequency of maintainers and environmental instability of the male sterility. On the other hand, the Pampa cms system in rye (Secale

Cell nuclei have lower refractive index and mass density than cytoplasm

Journal of Biophotonics, 2016
Common perception regards the nucleus as a densely packed object with higher refractive index (RI) and mass density than the surrounding cytoplasm. Here, the volume of isolated nuclei is systematically varied by electrostatic and osmotic conditions as ...

Androgen receptor phosphorylation at serine 515 by Cdk1 predicts biochemical relapse in prostate cancer patients [PDF]

, 2013
<br>Background:Prostate cancer cell growth is dependent upon androgen receptor (AR) activation, which is regulated by specific kinases. The aim of the current study is to establish if AR phosphorylation by Cdk1 or ERK1/2 is of prognostic ...

Molecular bases of circadian magnesium rhythms across eukaryotes

FEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...
