Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Diosgenin Modulates Vascular Smooth Muscle Cell Function by Regulating Cell Viability, Migration, and Calcium Homeostasis

open access: yes, 2010
In this study, we compared the potencies of diosgenin, a plant-derived sapogenin structurally similar to estrogen and progesterone, on vascular smooth muscle functions ranging from contraction and migration to apoptosis.

A linear shear model of cell viability loss during hepatocyte transplantation

open access: yesJournal of Biomechanical Science and Engineering, 2017
Improving the process of cell injection during hepatocyte transplantation requires an understanding of the causal relationships that shear, direct contact cells with a solid surface, and cell deformation have on cell viability loss.

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

open access: yesMolecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Quantitative ratiometric Ca2+ imaging to assess cell viability

open access: yes, 2017
Viability of cells is strongly related to their Ca2+ homeostasis. Ca2+ signal fluctuations can be on a slow time scale, e.g., in non-excitable cells, but also in the range of tens of milliseconds for excitable cells, such as nerve and muscle.

Cell population, viability, and some key immunomodulatory molecules in different milk somatic cell samples in dairy cows [PDF]

open access: yes, 2009
Immune cells in the milk are most important in combating pathogens that invade the mammary gland. This study investigated the immune competence and viability of somatic milk cells that are already resident in milk and udders free of infection. Cells were

Study of Cisplatin effects in comparison with Curcumin on Cdc42 gene expression in human Calu-6 lung carcinoma cell line

open access: yesیافته‌های نوین در علوم زیستی, 2022
Lung carcinoma is the second most common type of cancer. Inefficiency of the current treatments and the undesirable side effects of chemotherapy drugs made the know-how of the treatment important.

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

open access: yesMolecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.
