I therapy is clinically unfeasible for anaplastic thyroid carcinoma (ATC), due to lack of active targets and ATC's resistance to radiation. Novel radionuclide-labeled targeted nano-drug delivery systems have exhibited the potential of prominent tumor imaging and remedy. Capitalizing on recent research achievements in nanotechnology and nuclear medicine, we sought to develop a radiolabeled nano-drug, which could specifically accumulate in ATCs via tumor-selective targeted delivery system and which could treat the tumors with both targeted and radionuclide therapeutics.

Article Synopsis
  • Cervical cancer (CC) is a serious health issue for women, and scientists want to understand how it spreads. This study looks at a molecule called SNHG3 to see how it might be linked to the spread of CC.
  • The researchers found that SNHG3 is more active in CC tissues and when it's turned off, the cancer cells don’t move as much or invade other areas.
  • They discovered that SNHG3 affects certain proteins that are involved in how cancer cells behave, which could help in finding new ways to treat or stop the spread of cervical cancer.

Background: Spatial chromatin structure is intricately linked with somatic aberrations, and somatic mutations of various cancer-related genes, termed co-mutations (CoMuts), occur in certain patterns during cancer initiation and progression. The functional mechanisms underlying these genetic events remain largely unclear in thyroid cancer (TC). With discrepant differentiation, papillary thyroid cancer (PTC) and anaplastic thyroid cancer (ATC) differ greatly in characteristics and prognosis.

Severe acute respiratory syndrome virus 2 (SARS-CoV-2) belongs to the single-stranded positive-sense RNA family. The virus contains a large genome that encodes four structural proteins, small envelope (E), matrix (M), nucleocapsid phosphoprotein (N), spike (S), and 16 nonstructural proteins (nsp1-16) that together, ensure replication of the virus in the host cell. Among these proteins, the interactions of N and Nsp3 are essential that links the viral genome for processing.

Platinum-based drugs such as cisplatin are widely used in combination chemotherapy for non-small cell lung cancer (NSCLC) owing to their high clinical response rate; however, acquired resistance to cisplatin is eventually inevitable. Circular RNAs (circRNAs) are involved in the development of diverse types of cancers, but their connection to cisplatin-resistance in NSCLC has not been studied. In the present study, two cisplatin-resistant NSCLC cell lines (A549/DDP and PC9/DDP) were established by gradually increasing concentrations of cisplatin in the media.

The immunosuppressive function of mesenchymal stem cells (MSCs) is well known. Aryl hydrocarbon receptor (AhR), a transcription factor of the bHLH/PAS family, is widely expressed in several cells and is involved in various physiological and pathological processes. Previously, we found that the expression of AhR was downregulated in MSCs isolated from mice with neutrophilic asthma and that the activation of AhR enhanced the function of MSCs to alleviate neutrophilic asthma.
