- Covalent modification of target proteins is a well-established mechanism of action for small molecule inhibitors. Cysteine residues in particular have been exploited for their reactivity toward electrophilic molecules. SAMT-247 is a mercaptobenzamide thioester that covalently acetylates cysteines in the zinc-coordinating domains of the HIV nucleocapsid protein. This SAMT-247-promoted reaction leads to loss of zinc binding by the protein, with concomitant loss of protein structure and function. Although it has low cytotoxicity in animal models, recent studies have indicated that it affects other protein targets in uninfected cells, for example leading to increased immune cell functions. In this study, global proteomics approaches have been used to better understand other protein targets of SAMT-247. Minimal effects are observed when unstimulated THP-1 monocyte cells were treated with SAMT-247. In contrast, thermal proteome profiling identified 170 proteins with altered thermal stability when THP-1 cells were stimulated with phorbol 12-myristate 13-acetate/Ionomycin (PMA/Iono) before SAMT-247 treatment. Among the affected proteins, 81 contain a zinc-coordinating domain and/or have been shown to have a reactive cysteine residue. Among these, several play a role in cellular metabolism, and Seahorse assays demonstrated that SAMT-247 significantly increased the anti-metabolic and pro-glycolytic effect of PMA/Iono in THP-1 cells. Two of the most-affected proteins were ZC3H7A, a microRNA-binding protein with four zinc finger domains, and MGMT, a DNA damage repair protein with a reactive cysteine. Both proteins were modified by SAMT-247 when tested alone or in the presence of THP-1 cell lysate, indicating that they are bona fide targets of the inhibitor. The low activity of SAMT-247 in unstimulated THP-1 cells is consistent with its low cytotoxicity. The increased effects of SAMT-247 in stimulated immune cells suggests that this molecule could be developed to target diseases other than HIV. - Source: PubMed

Rekhi BharatKavuncuoglu AltanDin Nasir UdRastogi SameerAbdelsatir AliStoehr RobertAgaimy AbbasKosemehmetoglu Kemal - BCOR-rearranged sarcomas constitute ultra-rare tumors. Among these, ZC3H7A/B::BCOR sarcomas are less common and are primarily reported as a subset of high-grade endometrial stromal sarcomas, as well as in the spectrum of malignant ossifying fibromyxoid tumors (OFMTs). Herein, we present the clinicopathological, immunohistochemical, and molecular profiles of seven soft tissue tumors exhibiting ZC3H7A/B::BCOR fusions. The patient's age ranged from 13 to 65 years (median = 38). Locations were neck (2) and one case each in the paraspinal region, scalp, gluteal region, chest wall, and thigh. Histologically, the tumors were composed of round to polygonal or spindle-shaped cells with a variable amount of fibromyxoid stroma, lacking bone shell or ossification, leading to a range of initial differential diagnoses. Immunohistochemically, the tumor cells were positive for S100 (5/6), cyclin D1 (2/3), SATB2 (2/3), BCOR (2/4), and TLE1 (1/3) while negative for MUC4 (0/6), keratin (0/5), EMA (0/4), desmin (0/6), CD34 (0/6), SMA (0/5), SOX10 (0/5), and melanoma cocktail (0/2). Targeted RNA sequencing revealed ZC3H7B::BCOR fusions in six tumors (four with ZC3H7Bex10::BCORex6 and one each ZC3H7Bex12::BCORex7 and ZC3H7Bex12::BCORex6). One tumor revealed a ZC3H7Aex10::BCORex6 fusion. All seven tumors were resected, mostly with clear margins (5/7), including two patients who received adjuvant therapy. Three of four patients with available follow-up (mean = 45 months) died of disease, while one patient was alive with multiple bone metastases. This series comprises seven additional ZC3H7A/B::BCOR soft tissue sarcomas associated with aggressive clinical outcomes. Whether this aggressive sarcoma represents a molecular subtype of malignant OFMT or a genetic variant of BCOR-rearranged sarcomas remains to be further verified. - Source: PubMed

Rekhi BharatKavuncuoglu AltanDin Nasir UdRastogi SameerAbdelsatir AliStoehr RobertAgaimy AbbasKosemehmetoglu Kemal - -kinase-activating gene rearrangements occur in approximately 1-2% of non-small-cell lung carcinomas (NSCLCs). Their reliable detection requires next-generation sequencing (NGS), while conventional methods, such as immunohistochemistry (IHC), fluorescence in situ hybridization (FISH) or variant-specific PCR, have significant limitations. We developed an assay that compares the level of RNA transcripts corresponding to 5'- and 3'-end portions of the gene; this test relies on the fact that translocations result in the upregulation of the kinase domain of the gene and, therefore, the 5'/3'-end expression imbalance. The present study included 16,106 consecutive NSCLC patients, 14,449 (89.7%) of whom passed cDNA quality control. The 5'/3'-end unbalanced expression was observed in 184 (1.3%) tumors, 169 of which had a sufficient amount of material for the identification of translocation variants. Variant-specific PCR revealed rearrangements in 155/169 (91.7%) tumors. RNA quality was sufficient for RNA-based NGS in 10 cases, 8 of which carried exceptionally rare or novel ( and ) translocations. We also applied variant-specific PCR for eight common rearrangements in 4680 tumors, which emerged negative upon the 5'/3'-end unbalanced expression test; 33 (0.7%) of these NSCLCs showed fusion. While the combination of the analysis of 5'/3'-end expression imbalance and variant-specific PCR allowed identification of translocations in approximately 2% of consecutive NSCLCs, this estimate approached 120/2361 (5.1%) in /////-negative carcinomas. -rearranged tumors obtained from females, but not males, had a decreased level of expression of thymidylate synthase ( < 0.00001), which is a known predictive marker of the efficacy of pemetrexed. The results of our study provide a viable alternative for testing in facilities that do not have access to NGS due to cost or technical limitations. - Source: PubMed
