(A) Lt, Increased miR-372 expression in CDDP resistance (CDDP-R) and taxol resistance (taxol-R) SAS cell subclones relative to the parental cells. Rt, ZBTB7A expression is slightly downregulated in these cell subclones. (B,C) Apoptosis assay. Cells with transient ZBTB7A knockdown (in B , Lt), as well as the stable knockdown cell subclone (in C ), were treated with CDDP or taxol to induce apoptosis. (B) Rt, quantification of the presence of apoptotic cells. Lt, ZBTB7A knockdown decreases the apoptosis induced by the above drugs. (D) Quantification of the apoptotic cells. CDDP-induced apoptosis is enhanced by 3MA treatment, but not by Ferrostatin-1 treatment. Taxol-induced apoptosis is slightly enhanced by 3MA treatment, but not by Ferrostatin-1 treatment. (E) Western blot analysis. Differential ZBTB7A expression in sh-ZBTB7A (7332) knockdown, ZBTB7A exogenous expression and both knockdown and expression subclones. (F–H) Cell viability assays.

CBL0137 inhibits B-NHL cell proliferation by inducing cell cycle arrest and promoting <t>apoptosis.</t> A Cell viability of B-NHL cells treated with various concentrations of CBL0137 for 24 h was measured by CCK-8 assay. B B-NHL cells were treated with 0.5 μM, 1.0 μM, 1.5 μM, 2.0 μM CBL0137, and 2.0 μM doxorubicin for 24 h, 48 h, and 72 h. The absorbance values at 450 nm were determined. C Cell proliferation was detected by colony formation assay after 24 h treatment with CBL0137 (1.0 μM). D The cell cycle was determined by flow cytometry. The percentages of cell cycle phases were shown in the bar chart. CBL0137 induced a significant increase in the proportion of B-NHL cells in S phase. E The expression of cyclins, CDKs, c-MYC, p21, and p53 was detected by western blotting in B-NHL cells treated with CBL0137. F Four B-NHL cells (SU-DHL-4, Farage, Raji, and Jeko-1) were treated with specified concentrations of CBL0137 for 24 h. Cell apoptosis was assessed by the Annexin <t>V-FITC</t> Apoptosis Detection Kit and flow cytometry. Representative results are shown on the left and statistical results are shown on the right. G B-NHL cells were treated with different concentrations of CBL0137 for 24 h and then were collected, and chromosomal DNA was isolated and purified using DNA Ladder Detection Kit according to manufacturer's instructions to explore the effect of CBL0137 on DNA fragmentation in B-NHL cells.

ZBTB7A expression is associated with the expression of death receptors and the phosphorylated isoforms of p53 in OSCC cells. (A,B,D) SAS cells. (A) Apoptosis array. A panel of 35 antibodies including various forms of phosphorylated p53 were measured in duplicate using this array. The ZBTB7A knockdown cell subclone and the control cells were treated with CDDP for 24 h, and then the array was used to identify changes in various apoptosis factors. Lt, a diagram of the array. White rectangles indicate duplicates exhibiting significant changes in signal following ZBTB7A knockdown. Rt, a heat-map demonstrating the changes in protein profile following ZBTB7A knockdown. The 3rd lane represents the average value of the duplicate signals in the upper two lanes. Vertical lines define the 20 proteins that are downregulated >30% (Lt region) or that are upregulated >12% (Rt region). (B) RNA sequencing. A heat-map showing the changes in transcript levels in the ZBTB7A subclone. The genes selected for analysis are TRAIL-R1, TRAIL-R2, Fas and the various phosphorylated isoforms of p53 and many of these were downregulated following knockdown of ZBTB7A; thus these are to be considered as ZBTB7A targets during apoptosis modulation.

Expression of TRAIL-R1, TRAIL-R2, Fas, and p53 phosphorylated at serine 15 is correlated with ZBTB7A expression (in C ), and is inversely correlated with ZBTB7A knockdown (in C ) and miR-372 expression (in D ) in OSCC cells. (E) qRT-PCR analysis. This shows the concordant changes in TRAIL-R1 and TRAIL-R2 mRNA expression in OSCC cells following ZBTB7A knockdown/expression. (F,G) Promoter activity assay.

Schematic summary of the role and mechanism of PDCD10 in acquired TMZ-resistance. Knockdown of PDCD10 (shPDCD10) in GBM cells significantly increased cell survival in response to TMZ treatment, and strongly promoted tumor cell regrowth in the post-treatment phase, which collectively accounted for acquired TMZ-resistance. Mechanism studies revealed that the loss of PDCD10 modulated the expression of DNA damage response genes (i.e., upregulating MGMT and downregulating MMR genes MSH2 , MSH6 , and PMS2 ), and altered the cell cycle process, as evidenced by the evasion of tumor cells from arrest at the G2/M phase, and the increase in tumor cells in the proliferating S phase. In addition, shPDCD10-GBM cells exhibited higher cell plasticity, as demonstrated by an increased capacity for colony formation and transformation of shPDCD10-GBM cells into GSC-like cells that expressed higher levels of the stem cell markers Nestin and KLF4. In support of these findings, overexpression of PDCD10 (oxPDCD10) induced contrary changes in the molecular and cell behaviors observed in shPDCD10-GBM cells, increasing the sensitivity of oxPDCD10-GBM cells to TMZ treatment and suppressing tumor cell regrowth after TMZ treatment. Our results indicate that PDCD10 plays a pivotal role in acquired TMZ-resistance and thus represents a promising target for perturbing TMZ-resistance and tumor recurrence.
