Fibroblasts could provide New Target for Treatment of Rheumatoid Arthritis

Synovial Fibroblasts (SFs) - pictured below - are cells that make up part of the connective tissue, or synovium, around human joints. In RA patients, SF cells cause damage by invading and attacking the cartilage and bone around the joint.

A study reveals the key role of different types of fibroblast cells in the development of rheumatoid arthritis (RA), opening up a new avenue for research into treatment of the disease. Synovial Fibroblasts (SFs) are cells that make up part of the connective tissue, or synovium, around human joints. In RA patients, SF cells cause damage by invading and attacking the cartilage and bone around the joint.

A team from University of Birmingham’s Institute of Inflammation and Ageing identified 2 distinct types of SF within the synovial membrane...

Bringing Silicon to Life: Scientists persuade Nature to make Silicon-Carbon bonds

They had created an enzyme that can selectively make silicon-carbon #bonds #15X more #efficiently than the best catalyst invented

An enzyme was created via directed evolution to make silicon-carbon bonds 15X more efficiently than the best catalysts invented

A new study is the first to show that living organisms can be persuaded to make silicon-carbon bonds – something only chemists had done before. Scientists at Caltech “bred” a bacterial protein to make the humanmade bonds – a finding that has applications in several industries. Molecules with silicon-carbon, or organosilicon, compounds ar

gricultural chemicals, paints, semiconductors, and computer and TV screens. Currently, these products are made synthetically, since the Si-C bonds are not found in nature.

The new study demonstrates biology can be used to manufacture these bonds in ways that are more environmentally friendly and potentially much less expensive...

Human cells with a ‘built-in circuit’ help prevent tumor growth

The attached image shows microscope images of the engineered cells (nuclei in blue) with HIF-1 visualized (in red). In the left hand panel, cells are in hypoxia but no doxyxyclin is present, therefore HIF-1 remains active (red dots). In the right hand panel, the cells are grown in hypoxia and in the presence of doxyxyxlin, therefore the cyclic peptide inhibitor is produced and HIF-1 is inhibited, as demonstrated by the absence of the red dots.

Researchers at the University of Southampton have engineered cells with a ‘built-in genetic circuit’ that produces a molecule that inhibits the ability of tumors to survive and grow in their low oxygen environment...

Researchers discover Novel Mechanism to Stop the Spread of Breast Cancer

Stage IV is when the invasive breast cancer has spread beyond the breast to nearby lymph nodes to other organs, such as the lungs, skin, bones, liver, and the brain, This may also be called, advanced stage or mechanistic stage of cancer, IV cancer a be a reoccurrence of previous cancer that has spread to other parts of the body.

A team from Cancer Science Institute of Singapore (CSI Singapore) at the National University of Singapore (NUS) has found that controlling the levels of the TIP60 protein, which is a tumor suppressor, could potentially prevent the spread of breast cancer cells. Specifically, TIP60 interacts with two other proteins DNMT1 and SNAIL2, to inhibit the spread of cancer cells...
