Protein's work in eye lens suggests a way to tame cancer

How does a protein called connexin put the clamps on cancer? Researchers have now reported an explanation. In the future, cancer therapies could potentially be based on connexin molecules, the study suggests.

Authors: Rai SK Abstract Many infectious/communicable diseases (IDs) are endemic in Nepal. Until a decade and half ago, IDs were the major cause of both morbidity and mortality accounting 70% for both. However, as a result of various preventive measures implemented by both the state and non-state actors, the overall IDs have shown a changing (declining) trend. The most impressive decline has been seen in the intestinal helminth infection. Though the overall burden of IDs is decreasing, several newer infectious diseases (emerging infections) namely, dengue fever, scrub typhus, influenza (H5N1 and H1N1), and others a...

In many situations, a kinase/phosphatase complex signals dynamically in time and space through their reciprocal regulations and their cooperative actions on a substrate. This complex may be essential for malignant transformation and progression and can therefore be considered...

Authors: Li Q, Wu J, Chen S, Zhao Y Abstract The introduction of the theory of cancer stem cells (CSCs) has provided a new direction and perspective for our understanding of the nature and origin of tumors. Cancer stem cells are believed to be responsible for the treatment failure, drug tolerance, metastasis, and recurrence of tumors. However, it remains a challenge to identify or isolate tumor stem cells and determine their regulatory mechanisms. Therefore, further understanding of the biological characteristics and functions of CSCs is of great practical significance and value to develop new methods of tumor diag...

Preclinical tumor models are the foundation of translational cancer research. For exploring fundamental biologic mechanisms or designing new cancer therapies, in  vitro and in vivo models are the indispensable test environments in which countless discoveries have been made. Conventional models rely on immortalized cell lines that are notable for their reproducibility, convenience, and ease of use. Although these approaches continue to be widely used, their limitations are well known. In particular, these models are often criticized as poor reproductions of clinical tumors.

AbstractHyperthermia is a promising alternative modality for the conventional cancer treatments. Nanoparticle-mediated photothermal therapy (PTT) has been widely applied for hyperthermia cancer therapy by a near-infrared light irradiation. Some special nanoparticles can convert light energy into heat and destroy the tumor cells. Inspired from the photothermal efficacy of the gold nanoparticles, here we synthesized, characterized, and applied novel photothermal polyethylene glycol-curcumin-gold nanoparticles (PEG-Cur-Au NPs) in cancer PTT. The effect of PEG-Cur-Au NPs upon irradiation by an 808-nm laser on C540 (B16/F10) ce...

Senolytic compounds are those capable of selectively destroying senescent cells. They are useful because the buildup of senescent cells over time is one of the root causes of aging. A number of mechanisms have been discovered by which senescent cells can be provoked into self-destruction, such as bcl-2 inhibition or interference in FOXO4-p53 interactions. These examples are fairly well understood. Other mechanisms are known but less well understood; they require more work in order to proceed on the production of improved senolytic compounds. In some cases, however, the primary mechanism of action of a compound found...

Roleira, Georgina Correia-da-Silva, Natércia Teixeira The leading cause of cancer death in women around the world is breast cancer. The aromatase inhibitors (AIs) are considered a first-line treatment for estrogen receptor-positive (ER+) breast tumors, in postmenopausal women. Exemestane (Exe) is a powerful steroidal AI, however, despite its therapeutic success, Exe-acquired resistance may occur leading to t...
