Down regulation by a low-zinc diet in gene expression of rat prostatic thymidylate synthase and thymidine kinase

Nutrition & Metabolism, 2008
Background Zinc has a wide spectrum of biological activities and its deficiency is related to various abnormalities of cell metabolism. Methods Wistar male rats, at age of 4 weeks, were fed a low-zinc diet for six weeks.

Senotherapeutics for Knee Osteoarthritis

Medicinal Research Reviews, EarlyView.
ABSTRACT Osteoarthritis (OA) is a chronic disease that imposes a significant economic burden and deteriorates quality of life. Nevertheless, current therapeutic options for OA are limited to symptomatic remedies. As such, there is a high interest in novel methods for treating or preventing OA.

Metabolome Diversity Enhances Resistance of Intertidal Clams to Thermal Stress

Integrative Zoology, EarlyView.
Meretrix species are widely distributed intertidal bivalves in China with significant ecological and economic importance, which are sensitive to thermal stress. Our results showed that thermal environments of clam habitats shaped metabolome diversity, which can enhance the resistance of intertidal clams to thermal stress.

Umbilical Cord Blood–Derived Extracellular Vesicles Enhance Neurovascular Regeneration and Improve Erectile Function in a Mouse Model of Bilateral Cavernous Nerve Injury

Andrology, EarlyView.
ABSTRACT Background Erectile dysfunction (ED) secondary to cavernous nerve injury (CNI), such as that occurring after radical prostatectomy, remains a significant clinical challenge, particularly among patients who do not respond to phosphodiesterase Type 5 inhibitors (PDE5i).

Oncogenic BRAF and KRAS Promote Global DNA Hypomethylation Through a Directed Pathway That Upregulates TET3

Cancer Science, EarlyView.
Oncogenic BRAF and KRAS promote global DNA hypomethylation through a directed pathway that increases the levels of TET3, which helps drive tumorigenesis. ABSTRACT Aberrant epigenetic modification is one of the characteristics of the cancer genome.

An Adenovirus Vector Containing the Suicide Gene Thymidine Kinase for a Broad Application in Cancer Gene Therapy

Memorias do Instituto Oswaldo Cruz, 2002
Treatment of cancer using gene therapy is based on adding a property to the cell leading to its elimination. One possibility is the use of suicide genes that code for enzymes that transform a pro-drug into a cytotoxic product.

Evidence That the Protein Phosphatase Activity of PTEN Contributes to Embryonic Development and Tumor Suppression

Cancer Science, EarlyView.
Mice expressing only mutant PTEN Y138L, a protein which shows normal suppression of cellular AKT yet lacks protein phosphatase activity, die in utero, and heterozygous mice display a range of tumors. This indicates both the lipid and protein phosphatase activities of PTEN work together for normal tumor suppression and embryonic development.

Utilization of exogenous thymidine by Chlamydia psittaci growing in the thymidine kinase-containing and thymidine kinase-deficient L cells [PDF]

Journal of Bacteriology, 1976
The incorporation of [3H]thymidine into the deoxyribonucleic acid (DNA) of Chlamydia psittaci (strain 6BC) growing in thymidine kinase (adenosine 5'-triphosphate-thymidine 5'-phosphotransferase, EC 1.7.1.21)-containing L cells, L(TK+), and thymidine kinase-deficient L cells, LM(TK-), was examined by autoradiography. Label was detected over C.

To Treat or Not to Treat: Navigating Early‐Stage CLL in the Era of Targeted Therapy

European Journal of Haematology, EarlyView.
ABSTRACT Chronic lymphocytic leukemia (CLL) is most frequently diagnosed at early, asymptomatic stages (Rai 0/Binet A), in which a watch‐and‐wait strategy remains the standard of care, based on historical trials demonstrating no overall survival benefit from early treatment.

Transgenic selection and underlying mechanisms in apicomplexan parasites

The FEBS Journal, EarlyView.
Transgenic selection markers have driven genetic engineering in apicomplexans, enabling precise, iterative experiments. This review discusses mechanistic details of drug selection markers, strategies for marker recycling, and practical considerations for several clinically relevant parasites.
