SARS-CoV-2 NSP14 induces potent inflammation via NF-κB pathways, finds study

SARS-CoV-2 has a single-stranded RNA genome encoding both structural and non-structural proteins. Of these, the latter is known to play a variety of roles in viral replication and the assembly of new viral particles, as well as in suppressing cellular immune responses. A new study reports the activity of one such protein, the non-structural protein 14 (NSP14), which activates the inflammatory mediator NF-κB to trigger intense inflammation.

Study shows that breast cancer can be prevented with better contraception choices

Hormonal contraceptives, e.g. the pill, the patch, and the vaginal ring, contain synthetic hormones that prevent pregnancy by either stopping ovulation, changing the cervical mucus to stop sperm from passing through the cervix and finding an egg, or changing the womb's lining to prevent a fertilized egg from being implanted in it.

Lengthy treatment with low-dose 6-mercaptopurine inhibits resistant triple-negative breast cancer cells

The cover for issue 7 of Oncotarget features Figure 5, "SUM149-MA cells surviving a 6-MP treatment are sensitive to chemotherapeutic drugs," published in "Inhibition of resistant triple-negative breast cancer cells with low-dose 6-mercaptopurine and 5-azacitidine" by Singh, et al. which reported that the authors have reported that a lengthy treatment with low-dose 6-mercaptopurine, a clinically useful anti-inflammatory drug, inhibits such resistant cells.

Study provides a better understanding of the complex interplay of ncRNAs with gene regulation

Researchers at the University of Eastern Finland have discovered previously unknown non-coding RNAs (ncRNAs) involved in regulating the gene expression of vascular endothelial growth factors (VEGF), the master regulators of angiogenesis.

Hopeaphenol inhibits entry of SARS-CoV-2 variants of concern into cells

A new study, released as a preprint on the bioRxiv* server, reports promising results with the natural product hopeaphenol, which successfully prevented the entry of the virus into host cells.

Novel integrative genetic screening platform offers insights into role of DNA accessibility in cancer

In a new resource for the scientific community, published today in Nature Biotechnology, researchers in the lab of Neville Sanjana, PhD, at the New York Genome Center (NYGC) and New York University (NYU) developed CRISPR-sciATAC, a novel integrative genetic screening platform that jointly captures CRISPR gene perturbations and single-cell chromatin accessibility genome-wide.

Research opens up the possibility of dietary therapy for cancer

A research group at the RIKEN Center for Biosystems Dynamics Research (BDR) has discovered molecular events that determine whether cancer cells live or die. With this knowledge, they found that reduced consumption of a specific protein building block prevents the growth of cells that become cancerous.

Drug cocktail can effectively activate and expand muscle stem cells

Skeletal muscle – the type of muscle that attaches to bones and enables movement – is the most abundant tissue in the human body.

Scientists decode activation mechanism of SHP2 protein that can trigger cancer

There are many different types of cancer, but they all have one thing in common: errors in the signals that control normal cell behavior can cause uncontrolled cell growth and cell division, leading to a tumor.

POT1 gene linked to glioma development mediates its effects in a sex-specific manner

Researchers at Baylor College of Medicine and collaborators at other institutions have discovered that POT1, a gene known to be associated with risk of glioma, the most common type of malignant brain tumor, mediates its effects in a sex-specific manner.

Scientists identify protein that operates closely with a genetic mutation to spur lung cancer growth

Scientists at VCU Massey Cancer Center have identified a protein that operates in tandem with a specific genetic mutation to spur lung cancer growth and could serve as a therapeutic target to treat the disease.

Researchers develop an effective strategy to fight against chronic myelomonocytic leukemia

Leukemias are debilitating cancers of the hematopoietic or blood-forming cells of the bone marrow. Now, researchers at Tokyo Medical and Dental University describe an ingenious strategy against chronic myelomonocytic leukemia (CMML) wherein an antibody-drug conjugate (ADC) comprising a cytotoxic drug payload linked to an antibody that selectively targets specific cell lines effectively blocks malignant cell proliferation at source.

DNA supercoiling is involved in the control of gene expression

The (when stretched) two-meter-long DNA molecule in each human cell is continuously being unpacked and packed again to enable the expression of genetic information.

Study shows how signaling pathways operate on molecular and cellular levels

Scientists have made a pivotal breakthrough in understanding the way in which cells communicate with each other.

Is non-severe SARS-CoV-2 infection characterized by early T cell proliferation?

To date, little evidence has been documented regarding the immune responses after the onset of the symptoms or virus detection. Further, no cross-sectional studies have been conducted that define the time of infection. Thereby, no report is available that explains the relationship between the earliest immune responses to COVID-19 and temporal kinetics. New research deals with this research gap using blood transcriptomics, multiparameter flow cytometry, and T cell receptor (TCR) sequencing methods.

New exosome-coated stent repairs damaged tissue, heals vascular injury

Researchers from North Carolina State University have developed an exosome-coated stent with a "smart-release" trigger that could both prevent reopened blood vessels from narrowing and deliver regenerative stem cell-derived therapy to blood-starved, or ischemic, tissue.

Combination of tumor cell vaccine and checkpoint therapy creates effective immune response

A personalized tumor cell vaccine strategy targeting Myc oncogenes combined with checkpoint therapy creates an effective immune response that bypasses antigen selection and immune privilege, according to a pre-clinical study for neuroblastoma and melanoma.

Scientists describe the mechanisms that regulate embryonic stem cells

Scientists at the Proteomics Core Unit of the Spanish National Cancer Research Centre (CNIO), headed by Javier Muñoz, have described the mechanisms, unknown to date, involved in maintaining embryonic stem cells in the best possible state for their use in regenerative medicine.

Stem cell therapy could help restore debilitating age-related muscle loss

As the name implies, induced pluripotent stem cells can become any type of cell in our body, and scientists have evidence that when they prompt them to become muscle progenitor cells they can help restore the sometimes debilitating muscle loss that happens with age.

YAP inhibitors could facilitate targeted treatment of basal-like breast cancer

Targeted treatment of basal-like breast cancer could be facilitated by YAP inhibitors in the future. As reported by an MDC team headed by Walter Birchmeier in the scientific journal Cancer Research, this type of cancer requires the support of the YAP protein to stimulate the growth of cancer stem cells.
