Background: To determine the prognostic value of thyroid suppression therapy in patients with thyroid carcinoma, we studied the effect of thyroid-stimulating hormone (TSH) on the morphology, proliferation rate, and the T3, T4 production rate of primary thyroid carcinoma cells in culture.
Methods: From August 1997 to February 1998 tissues were collected for immediate culture from 13 patients undergoing surgery for thyroid cancer. Cells were incubated for 48 h with TSH in different concentrations. T3 and T4 production was measured by radioimmunoassay; cell proliferation was measured in a radioactive counter. Morphology was determined by cytologic examination.
Results: Ten samples were eligible for analysis. Changes in TSH affected T3 and T4 levels. The proliferation rate was not influenced by TSH levels.
Conclusions: Thyroid papillary carcinoma cells grown in culture maintain their T3 and T4 synthesis ability. This ability is TSH-dependent and correlates with TSH concentration. The morphology of the cells is also maintained. However, their proliferation is not TSH-dependent, placing the current postthyroidectomy treatment policy in question.

The importance of SUMOylation in tumorigenesis has received increasing attention, and research on therapeutic agents targeting this pathway has progressed. However, the potential function of SUMOylation during hepatocellular carcinoma (HCC) progression and the underlying molecular mechanisms remain unclear. Here, we identified that SUMO-Specific Peptidase 3 (SENP3) was upregulated in HCC tissues and correlated with a poor prognosis.

Background: Siglec-E is an immune checkpoint inhibitory molecule. Expression of Siglec-E on the immune cells has been shown to promote tumor regression. This study aimed to develop an adenovirus (Ad) vaccine targeting Siglec-E and carbonic anhydrase IX (CAIX) (Ad-Siglec-E/CAIX) and to evaluate its potential antitumor effects in several preclinical renal cancer models.

Background: Clear cell renal cell carcinoma (ccRCC) is the most common histologic type of RCC. However, the spatial and functional heterogeneity of immunosuppressive cells and the mechanisms by which their interactions promote immunosuppression in the ccRCC have not been thoroughly investigated.
Methods: To further investigate the cellular and regional heterogeneity of ccRCC, we analyzed single-cell and spatial transcriptome RNA sequencing data from four patients, which were obtained from samples from multiple regions, including the tumor core, tumor-normal interface, and distal normal tissue.

Introduction: Parkin-mediated mitophagy is essential for the clearance of damaged mitochondria, and it inhibits tumour development. The role of mitophagy in modulating tumour immunity is becoming clearer, but the underlying mechanism is still poorly understood.
Objective: This study was designed to examine the role for Parkin in the immune microenvironment of liver tumors induced by carbon tetrachloride (CCl).

This study aimed to define the antitumor effect of ethanolic extract of Pistacia vera leaves (PEE) toward breast cancer both in vitro and in vivo using dimethyl-benz(a)anthracene (DMBA)-induced breast tumor in adult female rats. PEE showed a potent antioxidant effect toward both DPPH (1,1-diphenyl-2-picrylhydrazyl) and ABTS (2,2'-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid) radicals with IC values of 72.6 and 107.
