Dendrimers in T cells
16 Feb 2022
This is a novel study that attempted to construct a pH-sensitive delivery system into T cells and their subsets using carboxy-terminal Phe- and CHex-modified dendrimers with different structures, i.e. PAMAM-CHex-Phe and PAMAM-Phe-CHex. The findings contribute to the development of nanoplatforms for direct delivery to T cells to control the functions of T cells, which play key roles in cancer immunotherapy. This is the first report on direct delivery into T cells using pH-sensitive DDS.
Chemoenzymatic synthesis and physico-chemical and biological functions of monocyclic polyketide compound, lankacyclinone C
31 Jan 2022
Garden soil houses a variety of bacteria and their natural byproducts — including one that may help halt tumor growth. Lankacidins are molecules that can be isolated from Strepomyces rochei, a common bacterium in soil. In addition to antimicrobial properties, a type of lankacidins, called lankacidin C, can inhibit tumor activity in various cancer cell lines, including leukemia, melanoma, ovarian and breast cancers. Lankacidin C offers a potential foundation on which to design anticancer drugs, but its structure is complicated and difficult to manipulate, according to an international research group. The same group recently identified where antitumor activity is housed on the molecule and has now used that information to simplify lankacidin as a potential starting point to engineer treatments.

Coral reefs, comprising some of the most diverse and delicate ecosystems under water, are under immense stress. From global warming to pollution to pathogens, many of the reef-building coral species are listed as threatened or endangered. But, according to researchers in Japan, the corals may have an unlikely ally: bacteria.

When it comes to cancer, clarity is key. The ability to visualize cancerous tumors and metastatic tissue three dimensionally (3D) can help clinicians diagnose the precise type and stage of cancer, while also informing the best treatment methods. To obtain an even clearer tissue for imaging, a research team based in Japan has tested the effectiveness of specialized hydrogels. Acting as a 3D molecular network, these hydrogels can rapidly remove fats from tissues, which are a factor in tissue opacification, without losing their structure. The material is used in several biomedical devices, including contact lenses.

Cells translate their genetic material at rapid rates with exquisite precision to reproduce, repair damage or even combat disease. But the process can deregulate and give rise to disease. Byproducts of errant processes can build up like gunk in the gears, especially around neurons, breaking down the repair mechanisms and causing further damage and even neurodegenerative disorders such as Alzheimer’s disease.

Publication bias, or the tendency of researchers and journals to not publish uninteresting findings, plagues much of the natural sciences and especially biomedical research. Hiroshima University researchers have developed a meta-analytic technique exploiting publicly available transcriptome databases that avoids the problem—and in so doing, discovered four genes previously unknown to be associated with responding to low-oxygen stress.

An international team led by Professor Yilin Wu, Associate Professor of the Department of Physics at The Chinese University of Hong Kong (CUHK) has made a novel conceptual advance in the field of active matter science. The team discovered a new route in which the self-organisation of active fluids in space and time can be controlled by a single material property called viscoelasticity. This new finding may pave the way for fabricating a new class of self-driven devices and materials, such as the ability to control the rhythmic movement of soft robots without relying on electronic circuits, and for the study of microbial physiology. It has been published in the scientific journal Nature.

Tissue stem cells can self-renew and differentiate, supplying cells necessary for tissues at various developmental stages. However, detailed analysis in vivo is difficult, so the molecular mechanisms underlying the stemness of gastric tissue stem cells have remained a mystery. Here, by using organoids that mimic tissue structure and function in vivo and GeCKO screening to inactivate arbitrary genes, Alk, Bclaf3 and Prkra have been identified as genes regulating stemness.
