Functional Sieve Element Protoplasts
SE protoplasts promise to be a powerful tool in studying the membrane biology of SEs with inherent implications for the understanding of long-distance transport and signaling

An efficient rapid system for profiling the cellular activities of molecular libraries
This methodology provides a powerful tool for unraveling the cellular biology and molecular pharmacology of both naturally occurring and synthetic chemical diversity.

Metal-Responsive Transcription Factors That Regulate Iron, Zinc, and Copper Homeostasis in Eukaryotic Cells
This review focuses on the role that metal-responsive transcription factors have in regulating trace metal metabolism.

Autophagy in the Eukaryotic Cell
This review focuses on the yeast S. cerevisiae because of the recent advances in understanding of the molecular mechanism of autophagy, pexophagy, and Cvt transport in this organism.

DNA and the chromosome – varied targets for chemotherapy
In this review, the authors discussed some of the new drugs aimed at primary DNA sequences, DNA secondary structures, and associated proteins.

TBLR1 regulates the expression of nuclear hormone receptor co-repressors
In this paper, the authors report the structure of the TBLR1 gene and analyze its pattern of expression.

Reversing cancer cells to normal cells
Tumor cells exposed to embryonic microenvironment of stem cells

Cancer cells 'reprogram' energy needs to grow and spread, study suggests
Studying a rare inherited syndrome, researchers have found that cancer cells can reprogram themselves to turn down their own energy-making machinery and use less oxygen

'Nurse cells' make life and death decisions for infection-fighting cells
"Nurse cells" play an important role in deciding which developing infection-fighting cells, called T cells, live and which die, according to research

A twist of fate -- Reprogrammed fibroblasts resemble embryonic stem cells
Stem cell biology takes another exciting leap forward as scientists report that normal tissue cells can be reprogrammed to exhibit many of the properties that are characteristic of embryonic stem cells

UCLA researchers reprogram normal tissue cells into embryonic stem cells
New technique could allow for cell reprogramming without use of controversial cloning methods

Cancer stem cells can go it alone
At the heart of most, if not all cancers, lie a handful of wayward stem cells that feed the ever growing tumor mass, but their scarcity make it difficult for scientists to study them.

Deakin University research finds rogue cells that could cause spread of breast cancer
Stephanie Lebret completed the study for her PhD at Deakin's Centre for Cellular and Molecular Biology under the supervision of Associate Professor Leigh Ackland.

Findings Offer Clue To How Molecule Can Both Stimulate, Suppress Cell Growth
Scientists are puzzled by the fact that the molecule known as transforming growth factor-beta (TGF-b) generally stops cells from multiplying but at other times promotes cell growth.

Extragenic suppression analysis of TS mutants using Sec61
During synthesis, secretory and membrane proteins are cotranslationally translocated into the lumen of the endoplasmic reticulum through an aqueous gated channel. Proper folding, degradation, and transport of many polypeptides depend on a diverse set of

New Research Identifies Human Enzyme That Could Be Programmed To Kill Cancer Cells
A new study conducted by scientists at Children's Hospital Oakland Research Institute (CHORI) identifies a specific enzyme that can cause the death of cancer cells.

One signal elicits thousands of answers
Cell signaling mechanisms often transmit information via protein modifications, most importantly the reversible attachment of phosphate, the so-called protein phosphorylation.

Needling Chromosomes Yields Insights Into Cell Division
By impaling individual chromosomes with glass needles one thousandth the diameter of a human hair, a Duke University graduate student has tested their "stickiness" to one another during cell division.

Why Is The Helix Such A Popular Shape? Perhaps Because They Are Nature's Space Savers
Something about nature loves a helix, the ubiquitous spiral shape taken on by DNA and many other molecules found in the cells of living creatures.

Elevated Testosterone Kills Nerve Cells
A Yale School of Medicine study shows for the first time that a high level of testosterone, such as that caused by the use of steroids to increase muscle mass or for replacement therapy, can lead to a catastrophic loss of brain cells.
