In August 1908, a white mob attacked Springfield, Illinois’s Black community, destroying homes and businesses and lynching two Black men. National outrage over the violence helped spur the movement that created the NAACP the following year.

Forkhead box protein K1 is a transcription factor of the forkhead box family that in humans is encoded by the FOXK1 gene.[5][6]
During starvation, in type 2 diabetes, in rapidly dividing cells during embryogenesis, in tumors (Warburg effect) and during T cell proliferation, aerobic glycolysis is induced to produce the building block to sustain growth. FOXK1 is one of the transcription factors managing the passage from the normal cellular respiration (complete glucose oxidation) to generating ATP and intermediaries for many other biochemical pathways.[7]
FOXK1 and its closely relate sibling FOXK2 induce aerobic glycolysis by upregulating the enzymatic machinery required for this (for example, hexokinase-2, phosphofructokinase, pyruvate kinase, and lactate dehydrogenase), while at the same time suppressing further oxidation of pyruvate in the mitochondria by increasing the activity of pyruvate dehydrogenase kinases 1 and 4. Together with suppression of the catalytic subunit of pyruvate dehydrogenase phosphatase 1 this leads to increased phosphorylation of the E1α regulatory subunit of the pyruvate dehydrogenase complex, which in turn inhibits further oxidation of pyruvate in the mitochondria—instead, pyruvate is reduced to lactate. Suppression of FOXK1 and FOXK2 induce the opposite phenotype. Both in vitro and in vivo experiments, including studies of primary human cells, show how FOXK1 and/or FOXK2 are likely to act as important regulators that reprogram cellular metabolism to induce aerobic glycolysis.[7]

FOX (forkhead box) proteins are a family of transcription factors that play important roles in regulating the expression of genes involved in cell growth, proliferation, differentiation, and longevity. Many FOX proteins are important to embryonic development. FOX proteins also have pioneering transcription activity by being able to bind condensed chromatin during cell differentiation processes. There are 50 different FOX genes encoding FOX proteins in humans that are further divided into 19 subdivisions based on conserved sequence similarity. The defining feature of FOX proteins is the forkhead box, a sequence of 80 to 100 amino acids forming a motif that binds to DNA. This forkhead motif is also called a winged helix, due to the butterfly-like appearance of the loops in the protein structure of the domain. FOX proteins are a subgroup of the helix-turn-helix class of proteins.
BRCA1 associated protein-1 (ubiquitin carboxy-terminal hydrolase) is a deubiquitinating enzyme that in humans is encoded by the BAP1 gene. BAP1 encodes an 80.4 kDa nuclear-localizing protein with a ubiquitin carboxy-terminal hydrolase (UCH) domain that gives BAP1 its deubiquitinase activity. Recent studies have shown that BAP1 and its fruit fly homolog, Calypso, are members of the polycomb-group proteins (PcG) of highly conserved transcriptional repressors required for long-term silencing of genes that regulate cell fate determination, stem cell pluripotency, and other developmental processes.
Zinc finger SWIM-type containing 9 is a protein encoded in humans by the ZSWIM9 gene. It is a member of zinc finger SWIM-type family. This gene is expressed in embryonic development and predicted to act in cell differentiation.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
